To maximize RF performance, the host layout should follow these recommendations:
1. Antenna Area Keepout: The host board directly below the antenna area of the Cypress module (see Figure 2 on page 5) must
contain no ground or signal traces. This keep out area requirement applies to all layers of the host board.
2. Module Placement: The ideal placement of the Cypress Bluetooth module is in a corner of the host board with the PCB trace
antenna located at the far corner. This placement minimizes the additional recommended keep out area stated in item 2. Please
refer to AN96841 for module placement best practices.
3. Optional Keepout: To maximize RF performance, the area immediately around the Cypress Bluetooth module chip antenna may
contain an additional keep out area, where there are no grounding or signal traces. The keep out area applies to all layers of the
host board. The recommended dimensions of the host PCB keep out area are shown in Figure 4 (dimensions are in mm).

CYBT-423028-02
Connections and Optional External Components
Power Connections (VDD)
The CYBT-423028-02 contains one power supply connection, VDD.
VDD accepts a supply input of 1.76 V to 3.63 V. Table 12 provides this specification. The maximum power supply ripple for this power
connection is 100 mV, as shown in Table 12.
Considerations and Optional Components for Brown Out (BO) Conditions
Power supply design must be completed to ensure that the CYBT-423028-02 module does not encounter a Brown Out condition,
which can lead to unexpected funcitonality, or module lock up. A Brown Out condition may be met if power supply provided to the
module during power up or reset is in the range shown below:
VIL
≤ VDD ≤ VIH
Refer to Table 17 for the VIL and VIH specifications.
System design should ensure that the condition above is not encountered when power is removed from the system. In the event that
this cannot be guaranteed (i.e. battery installation, high value power capacitors with slow discharge), it is recommended that an
external voltage detection device be used to prevent the Brown Out voltage range from occuring during power removal. Please refer
to Figure 8 for the recommended circuit design when using an external voltage detection IC.
Figure 8. Reference Circuit Block Diagram for External Voltage Detection IC
In the event that the module does encounter a Brown Out condition, and is operating erratically or not responsive, power cycling the
module will correct this issue and once reset, the module should operate correctly. Brown Out conditions can potentially cause issues
that cannot be corrected, but in general, a power-on-reset operation will correct a Brown Out condition.
External Reset (XRES)
The CYBT-423028-02 has an integrated power-on reset circuit which completely resets all circuits to a known power on state. This
action can also be envoked by an external reset signal, forcing it into a power-on reset state. The XRES signal is an active-low signal,
which is an input to the CYBT-423028-02 module (solder pad 11). The CYBT-423028-02 module does not require an external pull-up
resistor on the XRES input
During power on operation, the XRES connection to the CYBT-423028-02 is required to be held low 50 ms after the VDD power supply
input to the module is stable. This can be accomplished in the following ways:
The host device can connect a GPIO to the XRES of Cypress CYBT-423028-02 module and pull XRES low until VDD is stable.
XRES is recommended to be released 50 ms after VDD is stable.
If the XRES connection of the CYBT-423028-02 module is not used in the application, a 0.33 uF capacitor may be connected to the
XRES solder pad of the CYBT-423028-02 in order to delay the XRES release. The capacitor value for this recommended implementation is approximate, and the exact value may differ depending on the VDD power supply ramp time of the system. The capacitor
value should result in an XRES release timing of at least 50 ms after VDD stability.
The XRES release timing may be controlled by a external voltage detection IC. XRES should be released 50 ms after VDD is stable.
Refer to Figure 11 on page 18 for XRES operating and timing requirements during power on events.

HCI UART Connections
The recommendations in this section apply to the HCI UART (Solder Pads 3, 4, 5, and 6). For full UART functionality, all UART signals
must be connected to the Host device. If full UART functionality is not being used, and only UART RXD and TXD are desired or
capable, then the following connection considerations should be followed for UART RTS and CTS:
UART RTS: Can be left floating, pulled low, or pulled high. RTS is not critical for initial firmware uploading at power on.
UART CTS: Must be pulled low to bypass flow control and to ensure that continuous data transfers are made from the host to the
module.
External Component Recommendation
Power Supply Circuitry
It is not required to place any power supply decoupling or noise reduction circuitry on the host PCB. If desired, an external ferrite bead
between the supply and the module connection can be included. The ferrite bead should be positioned as close as possible to the
module pad connection.
If used, the recommended ferrite bead value is 330 Ω, 100 MHz. (Murata BLM21PG331SN1D).

Integrated Radio Transceiver
The CYBT-423028-02 has an integrated radio transceiver that has been designed to provide low power operation in the globally
available 2.4 GHz unlicensed ISM band. It is fully compliant with Bluetooth Radio Specification 3.0 and meets or exceeds the requirements to provide the highest communication link quality of service.
Transmitter Path
CYBT-423028-02 features a fully integrated transmitter. The baseband transmit data is GFSK modulated in the 2.4 GHz ISM band.
Digital Modulator
The digital modulator performs the data modulation and filtering required for the GFSK signal. The fully digital modulator minimizes
any frequency drift or anomalies in the modulation characteristics of the transmitted signal.
Power Amplifier
The CYBT-423028-02 has an integrated power amplifier (PA) that can transmit up to +4 dBm for class 2 operation.
Receiver Path
The receiver path uses a low IF scheme to downconvert the received signal for demodulation in the digital demodulator and bit
synchronizer. The receiver path provides a high degree of linearity, and an extended dynamic range to ensure reliable operation in
the noisy 2.4 GHz ISM band. The front-end topology, which has built-in out-of-band attenuation, enables the CYBT-423028-02 to be
used in most applications without off-chip filtering.
Digital Demodulator and Bit Synchronizer
The digital demodulator and bit synchronizer take the low-IF received signal and perform an optimal frequency tracking and bit
synchronization algorithm.
Receiver Signal Strength Indicator
The radio portion of the CYBT-423028-02 provides a receiver signal strength indicator (RSSI) to the baseband. This enables the
controller to take part in a Bluetooth power-controlled link by providing a metric of its own receiver signal strength to determine whether
the transmitter should increase or decrease its output power.
Local Oscillator
The local oscillator (LO) provides fast frequency hopping (1600 hops/second) across the 79 maximum available channels. The
CYBT-423028-02 uses an internal loop filter.

Peripheral and Communication Interfaces
I 2C
The CYBT-423028-02 provides a 2-pin I2C compatible master interface to communicate with I2C compatible peripherals. The following
transfer clock rates are supported are:
100 kHz
400 kHz
800 kHz (Not a standard I2C-compatible speed)
1 MHz (Compatibility with high-speed I2C-compatible devices is not guaranteed)
The clock pin (SCL) and data pin (SDA) are both open-drain I/O pins. Pull-up resistors external to the CYBT-423028-02 are required
on both the SCL and SDA pins configured for I2C operation. Cypress BSC does not support multimaster capability or flexible wait-state
insertion by either master or slave devices.
UART (HCI UART) Interface
The CYBT-423028-02 includes a UART interface for factory programming as well as when operating as a BT HCI device in a system
with an external host. The UART physical interface is a standard, 4-wire interface (RX, TX, RTS, and CTS) with adjustable baud rates
from 115200 bps to 3 Mbps typical rates are 115200, 921600, 1500000, and 3,000,000 bps although intermediate speeds are also
available. Support for changing the baud rate during normal HCI UART operation is included through a vendor-specific command.
The CYBT-423028-02 UART operates correctly with the host UART as long as the combined baud rate error of the two devices is
within ±5%. The CYBT-423028-02 has a 1040-byte receive FIFO and a 1040-byte transmit FIFO to support enhanced data rates. The
interface supports the Bluetooth UART HCI (H4) specification. The default baud rate for H4 is 115.2 kbaud.
The CYBT-423028-02 can wake up the host as needed or allow the host to sleep via the HOST_WAKE signal (Pad 2). HOST_WAKE
signals can be enabled via a vendor specific command.
The FW UART driver allows applications to select different baud rates.

Peripheral UART Interface
The CYBT-423028-02 has a second UART that may be used to interface to peripherals. This peripheral UART is accessed through
the optional I/O ports, which can be configured individually and separately for each functional pin. The CYBT-423028-02 can map the
peripheral UART to any GPIO. The Peripheral UART functions the same as the HCI UART, but with a 256-byte transmit and receive
FIFO.
Serial Peripheral Interface
The CYBT-423028-02 has two independent SPI interfaces. Both interfaces support Single, Dual, and Quad mode SPI operations as
well as MIPI DBI-C Interface. Either interface can be a master or a slave. SPI2 can support only one slave. SPI1 has a 1024 byte
transmit and receive buffer which is shared with the host UART interface. SPI2 has a dedicated 256 byte transmit and recieve buffer.
To support more flexibility for user applications, the CYBT-423028-02 has optional I/O ports that can be configured individually for
each functional pin.
SPI IO voltage depends on VDD.

GPIO Ports
The CYBT-423028-02 has a maximum of 17 general-purpose I/Os (GPIOs). All GPIOs support programmable pull-ups and pull-downs
with an internal pull-up/pull-down resistor value of ~45 Kohm. All GPIOs are capable of sourcing or sinking up to 8 mA at 3.3V or 4
mA at 1.8V. Pad 14 (P26) and Pad 19 (P29) are capable of driving up to 16 mA at 3.3V or 8 mA at 1.8V and include PWM functionality
for LED dimming.
The following GPIOs are available on the CYBT-423028-02 module:
p P0-P2, P4, P6, P7, P16, P17, P25, P26, P29, P33, and P38
p P10/P11 (Double bonded connection on the CYBT-423028-02 module, only one of two is available)
p P13/P23/P28 (Triple bonded connection on the CYBT-423028-02 module, only one of three is available)

PDM Microphone
The CYBT-423028-02 accepts a ΣΔ-based one-bit pulse density modulation (PDM) input stream and outputs filtered samples at either
8 kHz or 16 kHz sampling rates. The PDM signal derives from an external kit that can process analog microphone signals and generate
digital signals. The digital signal passes through the chip IO and MUX inputs using an auxADC signal. The PDM shares the filter path
with the auxADC. Two types of data rates can be supported:
8 kHz
16 kHz
The external digital microphone takes in a 2.4 MHz clock generated by the CYBT-423028-02 and outputs a PDM signal which is
registered by the PDM interface with either the rising or falling edge of the 2.4 MHz clock selectable through a programmable control
bit. The design can accommodate two simultaneous PDM input channels, so stereo voice is possible.
I2S Interface
The CYBT-423028-02 supports a single I2S digital audio port. with both master and slave modes. The I2S signals are:
I2S Clock: I2S SCK
I2S Word Select: I2S WS
I2S Data Out: I2S DO
nI S
Data In: I2S DI
I S SCK and I2S WS become outputs in master mode and inputs in slave mode, while I2S DO always stays as an output. The channel
word length is 16 bits and the data is justified so that the MSN of the left-channel data is aligned with the MSB of the I2S bus, per I2S
Specifications. The MSB of each data word is transmitted one bit clock cycle after the I2S WS transition, synchronous with the falling
edge of bit clock. Left Channel data is transmitted when I2S WS is low, and right-channel data is transmitted when I2S WS is high.
Data bits sent by the CYBT-423028-02 are synchronized with the falling edge of I2S SCK and should be sampled by the receiver on
the rising edge of the I2S SCK.
NOTE: The PCM interface shares HW with the I2S interface and only one can be used at a given time.

CYBT-423028-02
PCM Interface
The CYBT-423028-02 includes a PCM interface that can connect to linear PCM codec devices in master or slave mode. In master
mode, the CYBT-423028-02 generates the PCM_CLK and PCM_SYNC signals. In slave mode, these signals are provided by another
master on the PCM interface and are inputs to the CYBT-423028-02.The configuration of the PCM interface may be adjusted by the
host through the use of vendor-specific HCI commands.
NOTE: The PCM interface shares HW with the I2S interface and only one can be used at a given time.
Slot Mapping
The CYBT-423028-02 supports up to three simultaneous full-duplex SCO or eSCO channels through the PCM Interface. These three
channels are time-multiplexed onto the single PCM interface by using a time-slotting scheme where the 8 kHz or 16 kHz audio sample
interval is divided into as many as 16 slots. The number of slots is dependent on the selected interface rate (128 kHz, 512 kHz, or
1024 kHz). The corresponding number of slots for these interface rate is 1, 2, 4, 8, and 16, respectively. Transmit and receive PCM
data from an SCO channel is always mapped to the same slot. The PCM data output driver tristates its output on unused slots to allow
other devices to share the same PCM interface signals. The data output driver tristates its output after the falling edge of the PCM
clock during the last bit of the slot.
Frame Synchronization
The CYBT-423028-02 supports both short- and long-frame synchronization in both master and slave modes. In short frame synchronization mode, the frame synchronization signal is an active-high pulse at the audio frame rate that is a single-bit period in width and
is synchronized to the rising edge of the bit clock. The PCGM slave looks for a high on the falling edge of the bit clock and expects
the first bit of the first slot to start at the next rising edge of the clock. In long-frame synchronization mode, the frame synchronization
signal is again an active-high pulse at the audio frame rate; however, the duration is three bit periods and the pulse starts coincident
with the first bit of the first slot.
Data Formatting
The CYBT-423028-02 may be configured to generate and accept several different data formats. For conventional narrow band speech
mode, the CYBT-423028-02 uses 13 of the 16 bits in each PCM frame. The location and order of these 13 bits can be configured to
support various data formats on the PCM interface. The remaining three bits are ignored on the input and may be filled with 0s, 1s, a
sign bit, or a programmed value on the output. The default format is 13-bit 2’s complement data, left justified, and clocked MSB first.
Burst PCM Mode
In this mode of operation, the PCM bus runs at a significantly higher rate of operation to allow the host to duty cycle its operation and
save current. In this mode of operation, the PCM bus can operate at a rate of up to 24 MHz. This mode of operation is initiated with
an HCI command from the host.
Security Engine
The CYBT-423028-02 includes a hardware security accelerator which greatly decreases the time required to perform typical security
operations. Access to the hardware block is provided via a firmware interface (see firmware documentation for details).Thie security
engine includes:
Public key acceleration (PKA) cryptography
AES-CTR/CBC-MAC/CCM acceleration
SHA2 message hash and HMAC acceleration
RSA encryption and decryption of modulus sizes up to 2048 bits
Elliptic curve Diffie-Hellman in prime field GF(p)
Random Number Generator
This hardware block is used for key generation for Bluetooth.
Note: Availability for use by the application is subject to the support in WICED Studio.
Note: The Random Number Generator block must be warmed up prior to use. A delay of 500 ms from cold boot is necessary prior to
using the Random Number Generator.

Power Modes
The CYBT-423028-02 support the following HW power modes are supported:
Active mode: Normal operating mode in which all peripherals are available and the CPU is active.
Idle mode: In this mode, the CPU is in Wait for Interrupt (WFI) and the HCLK, which is the high frequency clock derived from the
main crystal oscillator, is running at a lower clock speed. Other clocks are active and the state of the entire chip is retained.
PDS mode: PDS mode is an extension of the PMU Sleep wherein most of the peripherals such as UART, and SPI are turned off.
The entire memory is retained, and on wakeup the execution resumes from where it was paused.
Shut Down Sleep (SDS): Everything is turned off except IO Power Domain, RTC, and the LPO. The device can come out of this
mode either due to BT activity or an external interrupt. Before going into this mode, the application can store some bytes of data
into the Always On RAM (AON). When the device comes out of this mode, the data from AON is restored. After waking from SDS,
the application will start from the beginning (warmboot) and has to restore its state based on information stored in AON. In the SDS
mode, a single BT task with no data activity, such as an ACL connection, BLE connection, or BLE advertisement can be performed.
HIDOFF (Timed-Wake) mode: The device can enter this mode asynchronously. That is, the application can force the device into
this mode at any time. IO Power Domain, RTC, and the LPO are the only active blocks. A timer that runs off the LPO is used to
wake the device up after a predetermined fixed time. This mode requires the use of an external XTAL oscillator.
HID-OFF (External Interrupt Waked) mode: This mode is similar to Timed-Wake, but in HID-OFF mode, the LPO and RTC are
turned off. The only wakeup source in HID-OFF mode is an external interrupt.
Firmware
The CYBT-423028-02 ROM firmware runs on a real time operating system and handles the programming and configuration of all
on-chip hardware functions. This include the BT/LE baseband, LM, HCI, GATT, ATT, L2CAP and SDP layers. The ROM includes
drivers for on-chip peripherals. In addition, the ROM also handles on-chip power management functions including transitions between
different power modes.
The CYBT-423028-02 is supported by the Cypress WICED Studio platform. WICED releases provide the latest ROM patches, drivers,
and sample applications allowing customized applications using the CYBT-423028-02 to be built quickly and efficiently.

Transmitter
Receiver
1. The system clock period T must be greater than Ttr and Tr because both the transmitter and receiver have to be able to handle the data transfer
rate.
2. At all data rates in master mode, the transmitter or receiver generates a clock signal with a fixed mark/space ratio. For this reason, tHC and
tLC are specified with respect to T.
3. In slave mode, the transmitter and receiver need a clock signal with minimum HIGH and LOW periods so that they can detect the signal. So
long as the minimum periods are greater than 0.35Tr, any clock that meets the requirements can be used.
4. Because the delay (tdtr) and the maximum transmitter speed (defined by Ttr) are related, a fast transmitter driven by a slow clock edge can
result in tdtr not exceeding tRC which means thtr becomes zero or negative. Therefore, the transmitter has to guarantee that thtr is greater than
or equal to zero, so long as the clock rise-time tRC is not more than tRCmax, where tRCmax is not less than 0.15Ttr.
5. To allow data to be clocked out on a falling edge, the delay is specified with respect to the rising edge of the clock signal and T, always giving
the receiver sufficient setup time.
6. The data setup and hold time must not be less than the specified receiver setup and hold time.

ESD and EMI Protection
Exposed components require special attention to ESD and electromagnetic interference (EMI).
A grounded conductive layer inside the device enclosure is suggested for EMI and ESD performance. Any openings in the enclosure
near the module should be surrounded by a grounded conductive layer to provide ESD protection and a low-impedance path to ground.
Device Handling: Proper ESD protocol must be followed in manufacturing to ensure component reliability.
