1.2 Description Summary
The SieMo-S50037 is a Class2 Bluetooth Module which can be integrated into various
electronic devices to give them Bluetooth functionality.
The connections to the enviroment consist of a single positive power supply, a 50 Ω Antenna
connector, UART, SPI, BCSP USB and PCM Interface, 6 PIO lines, control signals for an
external Power Amplifier and one Pin which allows to switch beetween two different firmware
versions. SieMo is shipped as an HCI Module, which means that the lower Bluetooth stack
up to HCI is included in the Firmware and it can be changed into a stand-allone Module with
the complete BT-stack and some simple applications running on the module via a firmware
upgrade.
The module supports synchronous voice transmission as well as asynchronous data transfer.

audio channels to be multiplexed onto a
single physical connection.
4.1 PCM Interface
4.1.3 Generic PCM Interface
4.1.1 Overview
PCM Pulse Code Modulation is a
standard method used to digitise
human voice
Four-wire, full duplex serial interface
used to transfer a single voice channel
to an external audio codec
Maximum of one SCO connection is
possible using the PCM interface
Further SCO channels must use the
HCI protocol layer
Data format is 13 bit linear PCM
4.1.2 Description
Pulse Code Modulation (PCM) is the
standard method used to digitise human
voice patterns for transmission over digital
communication channels. Through its
PCM interface, SieMo provides hardware
support for continual transmission and
reception of PCM data, thus reducing
processor overhead for wireless headset
applications.
SieMo offers a bi-directional digital audio
interface that routes directly into the
baseband layer of the on-chip firmware (it
does not pass through the HCI
protocollayer). Hardware on SieMo allows
the data to be sent to and received from a
SCO connection. Only one SCO
connection can be supported by the PCM
interface at any one time. Any additional
SCO connections must receive and
transmit their data over the HCI protocol
layer. The data format is 13-bit linear
PCM. SieMo can operate either as a
master (with an output clock of 256kHz) or
as a slave (with the input clock varying
between 128kHz and 512kHz). When in
slave mode and using higher clock rates
SieMo can support Motorola's
Synchronous Serial Interface (SSI)
standard that allows multiple bi-directional
For a generic PCM interface there is one
master and one slave device. The master
generates the clock and synchronisation
signals. The sync signal identifies the start
of the sample data and has an 8kHz
period. There are two types of frame sync:
long andshort. In long frame sync mode
PCM_SYNC going high indicates the first
(and most significant) bit of the sample. It
must remain high for at least two clock
cycles, but this can be longer. In short
frame sync MSB start is signalled by sync
going low (normally it only goes high for
one clock cycle).
The clock runs at a higher rate than sync:
at least 8 x bits_per_sample MHz,
although higher rates are common. The
sample resolution is 13 bits/sample,
uncompressed. Several Motorola
CODECs allow their output gain to be
controlled via the addition of three extra
data bits after the audio data. SieMo
supports this feature, effectively raising the
bits per sample to 16. Data from both the
master and slave is clocked out on the
rising clock edge and sampled on the
falling edge. Master mode is the default
setting. In master mode SieMo generates
a 256kHz clock signal (PCM_CLK) and the
8kHz, long format synchronisation signal
(PCM_SYNC). Short frame sync is not
supported. See PCM Timing Diagrams for
more information.
Slave mode is selected by setting a
Persistent Store value. In slave mode
SieMo clocks output data on the rising
edge of the received clock signal and
samples incoming data on the falling edge.
The incoming clock frequency should be
between 128kHz and 512kHz. (Note that
128kHz is 8 x 16 kHz, therefore the
absolute minimum possible frequency for
the 8ksamples/sec and 16bits/sample (13
audio data plus three gain data). The
frame sync must be long format. Short
format is not supported (see SSI Mode
and Timing Diagrams in this section for
moreinformation).

4.4 USB Interface
4.4.1 Overview
12Mbits/s bit rate
BC01 operates as a peripheral USB
device
Two modes, bus powered and self
powered
Careful product design is required for
product to remain USB1.1 compliant
4 USB lines are required
Minimum voltage on all VCC terminals
is 3.0V for USB operation
The SieMo contains its own full-speed
(12Mbits/s) USB interface. To get a
product USB 1.1 certified, please visit
www.usb.org for further information. The
voltage on Vcc-IO must be between 3.0
and 3.4 V for USB operation. It is possible
to connect the Vcc-IO to the Vreg output of
the module, which priveds a regulated
voltage of 3.15V.
Although SieMo is capable of meeting the
USB 1.1 specification, Siemens cannot
guarantee that an application circuit
designed around the IC is USB compliant.
The choice of application circuit,
component choice and PCB layout all
affect USB signal quality and electrical
characteristics. The information in this
document is intended as a guide and
should be read in association with the
USB 1.1 specification, with particular
attention being given to Chapter 7.
Independent USB qualification must be
sought before an application is deemed
USB compliant and can bear the USB
logo. Such qualification can be obtained
from a USB plugfest or from an
independent USB test house.
4.4.2 Disconnect and Resum e
Signalling
SieMo provides some signalling lines for
USB operation. These functions are
disabled by default but can be activated
via firmware settings.
The USB_DETACH and USB_WAKE_UP
terminals provide extra signalling
alongside the normal USB data lines. They
are not part of the USB specification and
full USB functionality can be attained
without their use. The Disconnect
message may be useful on its own, but it
is hard to see an application for
USB_RESUME in isolation.
USB_DETACH (Disconnect Signalling)
USB_DETACH is an input, when asserted
high, causes SieMo to put
USB_PULL_UP, USB_D- and USB_D+ in
a high-impedance state. This detaches the
device from the bus and is logically
equivalent to unplugging the module.
When USB_DETACH is taken low, SieMo
will connect back to USB and await
enumeration by the USB host.
USB_RESUME
USB_WAKE_UP is an active high output
used only when USB_DETACH is active to
wake-up the host and allow USB
communication to recommence. It
replaces the function of the USB Resume
message, which cannot be sent while
SieMo is effectively disconnected from the
bus.
4.4.3 Power Modes
SieMo is by default set to be powered from
the Bus. It can be set to a self powered
Device by changing firmware settings. In
this case the USB_ON must be connected
to the Vbus line via a 47k/22k

SieMo always acts in slave mode
SPI_CLK is always generated by the host
SieMo uses 16-bit addresses and 16-bit data during serial peripheral interface transactions.
Such transactions will operate regardless of whether the internal processor is running or is
stopped. This section details the considerations required when interfacing to SieMo via the
four dedicated Serial peripheral interface terminals.
4.5.2 Instruction Cycle
Before SieMo can be addressed, SPI_CSB must be taken low (SPI_CSB = 0). Data on
SPI_MOSI is then clocked into the SieMo on the rising edge of the clockline SPI_CLK. When
reading, SieMo will reply to the master on MISO, the data being valid on the falling edge of
the SPI_CLK. The master provides the clocking.

Technical Description
4.5.3 Single-Cycle Operation
After a serial peripheral interface transaction finishes, the master toggles SPI_CLK with
SPI_CSB high to initiate a new transaction. SPI_CSB must be high for at least two SPI_CLK
cycles.
4.5.4 Multi-Slave Operation
SieMo should not be connected in a multi-slave arrangement by simple parallel connection of
slave MISO lines. When SieMo is deselected (SPI_CSB = 1), the SPI_MISO line does not
float. Instead, SieMo outputs 0 if the processor is running or 1 if it is stopped.
4.5.5 Writing to SieMo
To write to the SieMo, the 8-bit write command (00000010) is sent first (C[7:0] followed by a
16-bit address (A[15:0]). 16 bits of data (D:[15:0]) are sent.

4.5.7 Reading from SieMo
Reading is similar to writing, in that an 8-bit read command (00000011) is sent first, followed
by the address of the location to be read. The SieMo then outputs the 16-bit contents of the
location on MISO during bits D[15:0] and a check-word during T[15:0].The check-word is
composed of {command, address [15:8]}. The check-word may be used to 'sanity-check' a
read operation to a memory location. This overcomes the problem encountered with typical
serial peripheral interface slaves, whereby it is impossible to determine whether the data
returned by a read operation is valid data, or the result ofthe slave device not responding.

4.5.8 Auto-Increment Operati on
Sending a command word and the address of a register every time it is to be read or written
can be a significant overhead, especially when large amounts of data are to be transferred.
SieMo offers increased data transfer efficiency via its auto-increment operation. During
operation, SieMo increments the address automatically. Only the data is transmitted or
received over the serial peripheral interface bus. SieMo keeps the previous command word.
