1. Introduction
TEA685X (‘Tiger-2’) is a series of low cost single-chip car radio devices. The devices are
consumer qualified and primarily intended for aftersales (‘non-OEM’) market use.
The Tiger-2 series consists of four variants with increasing functionality; TEA6850,
TEA6851, TEA6852 and TEA6853.
All Tiger-2 variants offer worldwide standard FM band reception as well as AM LW and
MW band reception. In addition to the TEA6850 feature set the TEA6851, TEA6852 and
TEA6853 offer FM-OIRT band reception and FM enhanced multipath suppression
(‘EMS’) for improved field performance. On top of that the TEA6852 and TEA6853
include RDS/RBDS data reception and the TEA6853 additionally offers connectivity and
support for digital radio operation as well as AM SW band reception up to 27 MHz.
This user manual describes the TEA685X series control interface or API (Application
Programming Interface). The document describes the available write and read
commands with parameter and data definitions.
This document version contains limited background information regarding the feature
functionality and the offered control options so some general knowledge of car radio
functions is required.
This user manual describes the functionality and control of the TEA685X device version
V102 specifically (TEA685X/V102).
2. Control interface
2.1 Overview
The TEA685X devices are equipped with an I²C bus interface for control of the device.
Full control of the device functions and features is available using this single interface.
The I²C bus supports bit rates of up to 400 kbit/s in accordance with the ‘fast mode’ I²C
bus specification.
The control interface is described in this document on an abstract ‘application’ level as
well as on I²C protocol level.
The TEA685X interface definition is compatible with the TEF668X (Lithio), the TEF665X
(Atomic-2) and the TEF701X (Sabre) series of devices, although differing in available
commands reflecting the available functionality.
Future NXP car radio devices will employ the same interface allowing compatible control
between device types, versions and variants.
Via the I²C bus commands and parameters can be written to the device and information
can be read from the device.
TEA685X control is organized in modules. Modules are independent functional blocks
that can be regarded sub-devices within the device.

The TEA685X consists of four modules:
module 32 : FM = FM radio reception
module 33 : AM = LW, MW and SW radio reception
module 48 : AUDIO = Audio processing
module 64 : APPL = System and application control
Different modules can be controlled independently even when the addressed module
itself is inactive at the time of control. This means modules can be prepared and
initialized before use.
Compatible command definitions have been used for the modules of FM and AM radio
where applicable. Defaults and range definitions may differ in some cases to fit the
different band properties.
Module commands have one or more parameters for control of the module behavior and
option selections.
The control is organized in such a way that future devices may support writing of a single
parameter up to writing of all parameters available for a given command.
Device version V102 however does not offer this flexibility and requires all command
parameters described in this document to be transmitted.

TEA685X device variants are fully control compatible, although differing in available
features. Future derivatives of these devices will remain compatible also but possibly with
a different variation and extension in supported functions and features.
The API template of TEA685X and compatible devices will be used in future NXP carradio developments also, offering compatible control with additional variation in
supported functions and features.
The parameter ranges as depicted in this document are the guaranteed ranges for
operation. Control outside of these ranges is not allowed for application.
The command parameters in general allow for a higher range and granularity than what
is available from TEA685X. Parameters can be set to any value within the documented
range even where the actual number of available settings is less than offered by the
parameter. In these cases the TEA685X will realize the nearest available setting.
Information regarding the actual available granularity is limited in this document but will
be extended in future user manual updates.
2.2 History
The control interface of the TEA685X has been improved over previous product
generations in order to ensure and offer:
Extendibility: Extension of modules, commands and parameters allowing addition
and extension of control options, features and functionality for future car radio
devices from low-end to high-end.
Granularity and range: The parameter definition allows for extremely detailed
parameter setting and range extension where needed in the future.
Reduced control effort: Although not supported for device version V102 the
interface definition allows for single parameter manipulation simplifying user
control software.
Although no direct compatibility is present it should be noted that the TEA685X command
interface shares most of its API functionality with previous products. A translation from
previous generation style control to the TEA685X control can therefore be made with little
effort. Description semantics and description units have been maintained between
generations to support easy transfer of settings.

3. Write commands
Write commands allow control or setting of specific features. Writing consists of a
module, a command and an index value generally followed by one or more parameter
values.
The module value defines the processing part that is addressed. Modules are integral
functional parts of the device that can be regarded sub-devices. Available modules in the
TEA685X are 32 ‘FM’ for FM radio’, 33 ‘AM’ for AM radio, 48 ‘AUDIO’ for audio
processing and 64 ‘APPL’ for application and system settings.
The command value defines a control function, a feature setting or a set of feature
settings.
The index value is present for future use to allow writing of certain specific parameter
parts out of the available command parameters.
Device version V102 requires index = 1 to be used and requires all command parameters
described in this user manual to be transmitted.
The first parameter starts from index = 1.
Write commands are only available in the device ‘active state’ operation modes with the
exception of certain APPL commands available during ‘idle state’.
Independent from the selected ‘active state’ operation mode (‘radio standby’, ‘FM’ or
‘AM’) the write commands of every module are available for writing so full device
initialization is possible in any of the ‘active state’ operation modes.
Note: FM radio and AM radio are never available together. Enabling of one radio module
(by a tuning action command on that module) will disable the other radio module but
control to the disabled radio module remains available for initialization purposes.
For detailed information on the I²C protocol for write commands see 5.2 Write control.

TEA685X tuning. The set of tuning actions offered by TEA685X is an NXP standard and
found in car radio devices for many generations.
The set of tuning actions frees the controlling C from all non-essential timing and control
complexity, however control flexibility is not limited in any way because the full ‘decision
intelligence’ remains at the C side. The tuning actions can be regarded building blocks
for creating the desired radio tuning control. Tuning actions can be chained together to
build complete tuning routines or realize a single basic routine by themselves.
A total of six mode tuning actions are defined for different types of tuning.
mode = 1 ; Preset
mode = 1 performs a complete ‘Preset-change’ tuning for tuning to a new program or
possibly to a new band. For a Preset-change it is desired to start the new program
immediately with the best quality possible, therefore time constants of the weak signal
handling and AM demodulator AGC are controlled for fast settling to the new signal
conditions within a small preset mute time of approx. 32 ms for FM and 60 ms for AM
bands.
mode = 2 ; Search:
mode = 2 performs a tuning action to create a search to a new program (previous / next
search) or searching for several programs (auto-store).
Search is equal in function to a Preset action however the mute is not released
automatically. This allows signal conditions to be checked while muted and when
insufficient reception quality is found a new Search action can be activated again and
again for a new frequency until a valid search stop condition is found.
Mute can then be released by an End action (mode = 7).
Also a Preset may be used as the last ‘search’ tuning action to release mute.
Preset and Search employ a 10 ms mute and de-mute slope timing for gentle program
switching, so actual tuning is delayed by 10 ms. In case mute is already active (like from
a previous Search action) no mute delay is present and tuning is started instantly.
A Preset and Search tuning action also allows for band switching between FM and AM.
An AM Preset or AM Search will disable ‘radio standby’ or ‘FM’ operation and enable AM
module operation. Equally an FM Preset or FM Search will enable FM module operation.
Note the 10 ms mute delay time should also be taken into account when switching
between FM and AM module operation.
mode = 3 ; AF_Update:
mode = 3 performs a complete ‘alternative frequency update’ tuning cycle for inaudible
testing of the quality of alternative frequencies in the background. AF_Update tunes to an
alternative frequency, gathers signal quality information and returns to the original
frequency within a very short time.

Inaudible mute is employed and the measured AF quality information is stored for easy
read-out by I²C. Time constants of the weak signal handling and DC decoupling are
controlled so they are not disturbed by the AF signal conditions.
A default AF_Update cycle finishes within 6 ms for the complete action including mute
enabling and disabling.
For AF_Update options like the bandwidth used during AF_Update tuning see 3.2 FM
cmd 2 Set_Tune_Options.
mode = 4 ; Jump:
mode = 4 performs a complete tuning action for switching to a ‘known’ alternative
frequency. Jump performs a tuning with a minimum mute time, only intended to suppress
PLL tuning disturbances. Starting from the control setting of the previous frequency the
weak signal handling will change gradually to the new signal conditions using the
standard weak signal timings, as desired for an inaudible switching to an alternative
frequency with the same program.
Since Jump releases mute automatically it must be assumed that the new frequency
indeed contains the same program. Should it later be found this is not the case (e.g. by
reading the RDS PI code) a new Jump is the designated tuning action for a fast return to
the original frequency.
mode = 5 ; Check:
mode = 5 performs a tuning action for switching to an ‘unknown’ alternative frequency.
Check is equal in function to a Jump action however the mute is not released
automatically. During the Check mute an RDS PI code can be searched for and verified
and if a valid program is found mute can be released by an End action (mode = 7).
During mute the weak signal handling is not disturbed by the new signal conditions and
after mute release the weak signal handling will gradually change to the new conditions
using the standard weak signal timings. In case an invalid program is found a Jump is the
designated tuning action for a fast return to the original frequency.
It is possible to string several Check transmissions together to create an AF_Update like
routine for checking several AF signal conditions in a row. Such a string of Check
transmissions may be finished by mode = End or Jump or, alternatively, by mode =
AF_Update in which case a ‘standard’ AF_Update is executed with quality data hold
while returning to the original frequency as present before the string of Check tunings.
Note: AF_Update, Jump and Check employ a 1 ms mute and de-mute slope timing for
fast inaudible switching, so actual tuning is delayed by 1 ms. In case mute is already
active (presumably by a previous Check action) no mute delay is present and tuning is
started instantly.
mode = 7 ; End:
mode = 7 ends a currently active tuning action. End releases the sustained mute of a
Search (mode = 2) or Check (mode = 5) tuning action.

Timing and quality sensitivity settings for the FM Stereo weak signal handling.
‘Set_Stereo_Time’ defines the weak signal handling response times active for the level
detector and noise and multipath detectors. Fast and slow response times are available
for dual timer functionality, with enable options at the level, noise and mph commands.’
‘Set_Stereo_Level’ sets the level sensitivity and enables slow and fast timing.
‘Set_Stereo_Noise’ and ‘Set_Stereo_Mph’ set the noise and multipath sensitivity and
enables slow and fast timing.
‘Set_Stereo_Max’ allows disabling the dynamic stereo control for evaluation purposes.

4. Read commands
Read commands make certain information available for read. Reading consists of writing
a module, a command and an index value (i.e. similar to a write command) followed by a
read of the requested data.
The module defines the processing part that is addressed. Modules are integral
functional parts of the device that can be regarded sub-devices. Modules in the TEA685X
offering read data are 32 ‘FM’ for FM radio, 33 ‘AM’ for AM radio and 64 ‘APPL’ for
application and system information.
The command value defines the set of read data of interest.
The index value is present for future use to allow reading of certain specific data parts
out of the available command read data.
Device version V102 requires index = 1 to be used.
For evaluation purposes also index = 0 is supported.
The first actual read data starts from index = 1.
For evaluation purposes reading may also start from index = 0 in which case the first
data word contains a confirmation of the data following (see 5.7.1).
Read commands are only available in the device ‘active state’ operation modes (with the
exception of certain APPL read commands) and only available for enabled modules.
idle state:
valid read data from ‘APPL’ read of operation status,
device identification and I²C write checking.
active state = radio standby:
valid read data from ‘AUDIO’ and ‘APPL’ module.
active state = FM:
valid read data from ‘AM’, ‘AUDIO’ and ‘APPL’.
active state = AM:
valid read data from ‘FM’, ‘AUDIO’ and ‘APPL’.
For detailed information on the I²C protocol for read commands see 5.3 Read control.

Get_RDS_Data returns status and data. The status and stored data (when complete
data is available) will be released allowing data updating. Get_RDS_Data is intended for
data reading including status information.
4.2.1 RDS read modes
The radio data system feature of FM RDS and RBDS data reception can operate in two
distinctive modes as defined by the FM cmd 81 Set_RDS mode parameter.
The mode setting defines the type of data available from the Get_RDS_Status and
Get_RDS_Data commands and the timing associated with ‘data-available’ signaling.
Decoder mode is the default mode (mode = 1) where the received RDS data is
additionally decoded and output in RDS group format as defined by the RDS standard.
Error correction is executed and error detection allows for discriminating between data
results judged reliable, less reliable and not reliable by the RDS error detection scheme.
The optional demodulator mode (mode = 2) allows for output of ‘raw’ RDS bit data
taken directly after demodulation. The data is output in 32 bit chunks for easy read-out.
Additional data processing is required in the connected C for RDS synchronization,
decoding and error handling.
In both modes RDS data is output through an internal data buffer capable of storing
multiple sets of output data for relaxed requirements on read timing.

The availability of RDS decoder data is signaled by the status bit 15.
If new and complete information is available this is signaled by status[15] = 1 and RDS
group status and data is stored for C read. RDS status and data can be read from
commands Get_RDS_Status and Get_RDS_Data equally but only the command
Get_RDS_Data clears the information from the internal storage buffer.
Optional an interrupt (‘DAVN’) can be generated at the occurrence of RDS data
available, see 3.17 FM cmd 81 Set_RDS to enable this option (interface = 2) and 3.31
APPL cmd 3 Set_GPIO for output pin selection of the data available interrupt signal.
The interrupt is set and released at the same conditions as the status[15] bit.

The RDS system includes an RDS data buffer capable of storing up to 22 RDS data sets
of group data allowing for a delayed read action on the data available signaling.
RDS data can be read from the device using Get_RDS_Data repeatedly with the data
available signal remaining active until the RDS data storage buffer is empty.
In the unlikely case that available data was not read in time causing the RDS data buffer
to become full and new group data is available then the oldest data will be overwritten by
new data. This loss of buffered data is indicated by the status bit 14 = 1.
Depending on the desired setup of the C control software three ways of operation are
suggested for the reading of RDS decoder data.
1. Non synchronized operation (data polling):
Repeated Get_RDS_Data read of RDS status and data.
When status[15] = 1 then the RDS data is used, otherwise the data is ignored.
To avoid data loss a single Get_RDS_Data read should be executed at least
every 87 ms. or a burst of up to 22 Get_RDS_Data reads should be executed at
least every 1.90 sec. taking advantage of the RDS data buffer.
2. Status synchronized operation (status polling):
Repeated Get_RDS_Status read of status[15].
When status[15] = 1 (i.e. data available) is found perform a Get_RDS_Data read
of RDS status and data.
To avoid data loss Get_RDS_Status the polling should be executed at least
every 87 ms. allowing for inclusion of a single Get_RDS_Data read or at least
every 1.90 sec. allowing for inclusion of up to 22 Get_RDS_Data reads taking
advantage of the RDS data buffer.

Setting of ‘DAVN’ interrupt output option and GPIO pin connected to C.
When interrupt active is found (pin low) perform a Get_RDS_Data read of RDS
status and data.
To avoid data loss a single Get_RDS_Data read should be performed within
87 ms. after interrupt or a burst of up to 22 Get_RDS_Data reads should be
executed within 1.92 sec. after interrupt taking advantage of the RDS data buffer.

4.2.5 RDS read for demodulator mode operation
Except for the different data content and associated timings the read operation for
demodulator mode equals the operation for decoder mode.
The availability of 32 bit of RDS demodulator data is signaled by the status bit.
If new and complete information is available this is signaled by status[15] = 1 and 32 bit
of raw RDS data is stored for C read. RDS status and data can be read from commands
Get_RDS_Status and Get_RDS_Data equally but only the command Get_RDS_Data
clears the information from the internal storage buffer.
Optional an interrupt (‘DAVN’) can be generated at the occurrence of RDS data
available, see 3.17 FM cmd 81 Set_RDS to enable this option (interface = 2) and 3.31
APPL cmd 3 Set_GPIO for output pin selection of the data available interrupt signal.
The interrupt is set and released at the same conditions as the status[15] bit.
The RDS system includes an RDS data buffer capable of storing up to 50 RDS data sets
of 32 bit raw data allowing for a delayed read action on the data available signaling.
RDS data can be read from the device using Get_RDS_Data repeatedly with the data
available signal remaining active until the RDS data storage buffer is empty.
In the unlikely case that the controlling C has not read the available data in time causing
the RDS data buffer to become full and again 32 bits of new data are available then the

oldest data will be overwritten by the new data. This loss of buffered data is indicated by
the status bit 14 = 1.
Depending on the desired setup of the C control software three ways of operation are
suggested for the reading of RDS demodulator data.
1. Non synchronized operation (data polling):
Repeated Get_RDS_Data read of RDS status and data.
If status[15] = 1 then the RDS data is used, otherwise the data is ignored.
To avoid data loss a single Get_RDS_Data read should be executed at least
every 26 ms. or a burst of up to 50 Get_RDS_Data reads should be executed at
least every 1.34 sec. taking advantage of the RDS data buffer.
2. Status synchronized operation (status polling):
Repeated Get_RDS_Status read of status[15].
When status[15] = 1 (i.e. data available) is found perform a Get_RDS_Data read
of RDS status and data.
To avoid data loss Get_RDS_Status the polling should be executed at least
every 26 ms. allowing for inclusion of a single Get_RDS_Data read or at least
every 1.34 sec. allowing for inclusion of up to 50 Get_RDS_Data reads taking
advantage of the RDS data buffer.
3. Interrupt synchronized operation (interrupt pin):
Setting of ‘DAVN’ interrupt output option and GPIO pin connected to C.
When interrupt active is found (pin low) perform a Get_RDS_Data read of RDS

5. I²C bus protocol
5.1 I²C protocol
TEA685X control parameters are 16 bit wide. The I²C bus native unit is the byte, multibyte values like 16 bit parameters are transmitted MSB byte first.
With external application of a pull down resistor at GPIO_2 (10 kto ground) the I²C
device address for TEA685X is C8h for write and C9h for read operations.
Alternatively application of a pull-up resistor (10 kto Vdd) at pin GPIO_2 allows for use
of device address CAh for write and CBh for read instead.
Note: GPIO_1 must be pulled low (10 kto ground) during power-on to ensure proper
operation.
Note: GPIO_2 must be pulled low or high (10 k) during power-on and activation for a
2
defined I C address. Pin open is not a defined state.
5.2 Write control
Standard write transmissions to the TEA685X consist of an I²C start condition and an 8
bit hardware device address for write as depicted by the I²C standard.
Next an 8 bit module identifier is transmitted that can be regarded as a kind of internal
device address for function blocks like FM radio, AM radio, audio and system.
Control is then indicated by an 8 bit command identifier and an 8 bit parameter index
allows for sub-addressing within the command parameter space, followed by one or
more 16 bit parameters for actual control.
The end of transmission is indicated by an I²C standard stop condition. Because the I²C
bus format includes this implicit stop condition no ‘size’ indication is needed as may be
required by certain other bus formats.
Note: Device version V102 only supports the use of index = 1 and all parameters
described in this user manual need to be transmitted.
In Fig 4 examples of these transmissions are shown.

TEA685X uses only a fraction of the possible number of modules, commands and
parameters. The choice for a 24 bit wide parameter address space is for future
extendibility.
Writing to disabled modules is supported and will store the data for later use. Enabling of
modules (where applicable) is supported by specific module commands which may imply
automatic disabling of other module(s) as e.g. is the case when switching between FM
and AM radio module operation.
5.3 Read control
Standard reading from the TEA685X consists of a write transmission for definition of the
requested data followed by the actual read transmission for obtaining the data.
Note: this is normal practice because the I²C specification does not support read
addressing within a read transmission.
Read data is 16 bit wide (or multiples of 16 bit) transmitted with the MSB byte first.
For reading of received data or status information special ‘get’ commands are defined.
For future extendibility and reading of data parts within larger data blocks an index
setting is included similar to the write definition.
Index = 1 is the standard case with read data starting from the first data word.
Note: Device version V102 only supports the use of index = 1, it is allowed however to
read less than the number of data words described in this user manual.
For evaluation purposes index = 0 is supported also (see 5.7.1).

5.4 I²C repeated start
The I²C specification allows the joining of multiple I²C transmissions by use of I²C
‘repeated start’. This way of operation ensures the set of I²C transmissions will not be
interrupted by another transmission from a second microcontroller on the bus (multimaster setup).
TEA685X supports the use of I²C ‘repeated start’ without restriction. This means
TEA685X handles I²C transmissions separated by an I²C stop and start condition in
exactly the same way as I²C transmissions ‘joined’ by an I²C repeated start condition.

Checking for presence of the device on the I²C bus without any data transfer is possible
by only writing of the device write address. The I²C standard acknowledge will signal
device presence.

Example of testing device presence.
5.6 I²C read timing requirements
The TEA685X supports I²C clock speeds up to 400 kHz in accordance with the I²C ‘fast
mode’ specification. TEA685X write operations require no special attention, read
operations however require a minimum of 50 us time to guarantee read data setup.
The 50 us timing requirement is measured from the write transmission finish to the first
read data; i.e. from the I²C ‘stop’ or ‘repeated start’ condition ( = SDA edge) to the end of
th
the device address ‘acknowledge’ ( = falling edge of the 9 SCL clock pulse)

For 400 kHz bus operation the special control option of index = 0 offers a simple solution
to meet this read timing requirement:
A setting of index = 0 will add an additional read word in front of the standard read data.
This read word allows for special transmission evaluation options (see chapter 5.7
Special control ) but can be ignored for normal operation. For 400 kHz operation the
special index 0 read word ensures a proper setup timing for the required read data of
index = 1 and higher. The special index 0 word itself however must be ignored.

Example of I²C read control with guaranteed 400 kHz operation; get command index = 0
Use of index = 0 is probably the most convenient way to ensure proper read data settling
2
for I C fast mode bus operation.
Three alternative operation means are depicted below that may be of use, e.g. when
reliable index = 0 read data is desired at high speed:
Alternative 1 : Maximum I²C bus speed limit.
A bus speed setting of 184 kHz or lower will guarantee the required data setup time.
Microcontrollers generally do not employ the ‘fast mode’ worst-case timing for the full
device address transmission meaning a microcontroller ‘200 kHz’ bus speed setting will
ensure safe read operation in many cases.
Alternative 2 : 400 kHz I²C bus speed with microcontroller delay.
Use of separate transmissions and a timed delay of 27 us or higher between the write
transmission ‘stop’ condition and the read transmission ‘start’ will guarantee the required
read data setup time.
Alternative 3 : 400 kHz I²C bus speed with dual ‘repeated-start’.
In case use of ‘repeated-start’ is desired as well as 400 kHz bus operation a ‘dummy’
write address transmission can be inserted between the functional write and read
transmission.

5.7 Special control
To support evaluation and debugging of the device control special control options are
available.
5.7.1 Set command confirmation; special evaluation read control
For standard operation data reading is limited to status and information read data
requested by a preceding ‘get’ command.
To this purpose TEA685X puts the requested data in its output registers after reception
and evaluation of a valid ‘get’ command. TEA685X however also places a data word in
its output registers after reception of a ‘set’ command, either offering confirmation of the
command reception by returning the module and cmd value or delivering an error code in
case of an invalid control. This data field is not intended for generic use but can be read
during control software development for debugging purposes.

5.7.2 Get command confirmation; special evaluation read control
For standard operation read command data reading is limited to application status and
information data.
However similar to write commands also read commands can optionally deliver
confirmation of the read command reception or an error in case of invalid control.
To this purpose use of index = 0 with a ‘get’ command has a special meaning where as
the first data word the module and cmd value are returned or an error code in case of
invalid control.
Condition :
Read data word :
Get command data available

FF FDh (currently only 0 and 1 are allowed)
FF FAh (command exists but not supported now)
* All TEA685X read commands show ‘instant’ data delivery, therefore error value FF F8h
shall never be found as long as the read timing requirement of 50 us is met (see 5.6).
In case of not meeting the read timing requirement also error value 00 00h may be found
occasionally.

6. Device start-up
6.1 Introduction
The TEA685X is powered by a single supply voltage. No supply power-up requirements
are known to exist.
After power-on the device is found in a pre-defined reset state (boot state). A sequence
of control transmissions will bring the device into idle state followed by active state to
realize the desired user operation mode, function and performance.

Boot state and idle state have no function other than offering the minimum set of controls
required for proper active state operation.
State transitions take a small amount of time and care should be taken to ensure a
certain state is entered before any of the belonging control transmissions is started. After
transmission of a ‘Start’ or ‘Activate’ state transition command it is advised to check the
2
operation status by I C read until the new state is found.
TEA685X state transition times will fall within the following limits:

Power-on Boot state
: power supply voltage settling + 5 ms.
(or clock active + 5 ms in case of external clock application)
Boot state Idle state
: 50 ms.
Idle state Active state
: 100 ms.

6.2.1 Required initialization I2C transmission – I2C example
2
The following I C transmissions (version p2.15) are a required part of the V102 boot state
device initialization.
2
Use of these I C transmissions is required for proper and full function and performance
as described in this user manual. Version p2.15 replaces previous versions and is a
critical update for AM shortwave use.
Note: The transmission example below shows a data content of 12 words for every ‘1B’
data transmission. The data stream can be split in any desired length on (2-byte) word
boundaries with every data transmission starting with hex value 1B.

6.3 Operation state description
6.3.1 Boot state
After power-on the device is found in ‘boot state’, controlled by the integrated power-onreset detection.
Parallel to the supply power detection a clock signal detector is present which ensures
boot state is entered only when a clock signal is present in order to safeguard the
external clock application case.
In case of a harmful disruption of the power supply voltage (power dip) or reference clock
signal the present operation state will be reset and boot state will be available after
power supply voltage and reference signal are re-established.
In boot state the device functionality is reduced to the bare minimum defined by
hardware only.
Required additions to the built-in firmware can be loaded up from the host C to the
internal RAM of the device.
‘Boot state’ is identified by
The I²C bus is active; I²C transmissions are acknowledged by the device.
(Note: the I²C device address has been determined during power-on).
The device is in full power-down.
GPIO and digital output pins are ‘open’.
No API commands are available; only hardware support.
API commands are ignored and do not harm the boot state operation.
Reading APPL_Get_Operation_Status returns ‘boot state’ (0).
Note: This API read operation is defined by the fact that any API read will return ‘0’ here.
This property can be used by the radio system C to detect an unforeseen power dip
occurrence or unforeseen disruption of the (external) clock reference signal.
The device can receive certain dedicated hardware commands and data;
Device version V102 requires an initialization at this point for function and
performance.
Command ‘Start’ will bring the device into ‘idle state’.
2
Note: The ‘Start’ command is made up of I C data byte values “14h 00h 01h”.
In API definition style this equals a transmission of module = 20, cmd = 0, index = 1 and
no parameters.
6.3.2 Idle state
Changing ‘boot state’ to ‘idle state’ takes a time of less than 50 ms.
Presence of ‘idle state’ can be verified by APPL_Get_Operation_Status returning ‘idle
state’ (status = 1).
In ‘idle state’ very limited control functionality is available, only specific API commands
required for system definition are available here.
‘Idle state’ is identified by

TEA6850, TEA6851, TEA6852 and TEA6853, /V102
The device is in power-down.
GPIO and digital output pins are ‘open’.
Reading APPL_Get_Operation_Status will return ‘idle state’ (1).
The device can receive certain API commands for application definition purposes
(APPL_Set_ReferenceClock).
The device can return certain API status information (APPL_Get_Identification,
APPL_Get_Last_Write).
Command APPL_Activate will bring the device into ‘active state’ = radio standby.
6.3.3 Active state
Changing ‘idle state’ to ‘active state’ takes a time of less than 100 ms.
Presence of ‘active state’ can be verified by APPL_Get_Operation_Status returning the
radio standby ‘active state’ (2).
On first activation pin states do not change and the device enters the reduced power
state of ‘radio standby’.
The full set of API commands is available now allowing initialization of the different
modules including the disabled modules of ‘FM’ and ‘AM’. The operation mode can be
completed now by enabling either FM or AM radio operation and releasing the audio
mute.
‘Active state’ is identified by
doc
User Manual
The I²C bus is active; I²C transmissions are acknowledged by the device.
The device is in operation (initial operation mode is ‘radio standby’)
At initial ‘radio standby’ operation the DR and GPIO pins are ‘open’.
In FM / AM operation the DR and GPIO pins are in their selected FM / AM state
(and default state ‘open’ when not initialized).
In ‘radio standby’ operation, after FM or AM, the DR pins remain in their previous
radio state (with invalid data) and GPIO radio features are disconnected (i.e.
GPIO pins are ‘open’).
Reading APPL_Get_Operation_Status will return one of the ‘active’ states; radio
standby (2), FM (3) or AM (4).
The device can handle API commands for all modules for additional initialization
and control including disabled modules like FM and/or AM.
API get commands result in valid read data for enabled modules only.
