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 chip antenna
located at the far corner. This placement minimizes the additional recommended keep out area stated in item 3 below. 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).

Connections and Optional External Components
Power Connections (VDD) The CYBT-4230xx-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 Brownout (BO) Conditions Power supply design must be completed to ensure that the CYBT-4230xx-02 module does not encounter a Brownout condition, which can lead to unexpected functionality, or module lock up. A Brownout condition may be met if power supply provided to the module during power up or reset is in the range shown below: VILVDD 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 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 Brownout voltage range from occurring during power removal. 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 Brownout condition, and is operating erratically or not responsive, power cycling the module will correct this issue and once reset, the module should operate correctly. Brownout conditions can potentially cause issues that cannot be corrected, but in general, a power-on reset (POR) operation will correct a Brownout condition.

CYBT-423054-02/CYBT-423060-02
External Reset (XRES) The CYBT-4230xx-02 has an integrated POR circuit which completely resets all circuits to a known power on state. This action can also be invoked by an external reset signal, forcing it into a POR state. The XRES signal is an active-low signal, which is an input to the CYBT-4230xx-02 module (solder pad 11). The CYBT-4230xx-02 module does not require an external pull-up resistor on the XRES input. During power on operation, the XRES connection to the CYBT-4230xx-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-4230xx-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-4230xx-02 module is not used in the application, a 0.33 µF capacitor may be connected to the
XRES solder pad of the CYBT-4230xx-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 , 100 MHz. (Murata BLM21PG331SN1D).

Bluetooth Baseband Core

The Bluetooth Baseband Core (BBC) implements all time-critical functions required for high-performance Bluetooth operation. The BBC manages the buffering, segmentation, and routing of data for all connections. It prioritizes and schedules all RX/TX activities including adv, paging, scanning, and servicing of connections. In addition to these functions, it independently handles the host controller interface (HCI) including all commands, events, and data flowing over HCI. The core also handles symbol timing, forward error correction (FEC), header error control (HEC), cyclic redundancy check (CRC), authentication, data encryption/decryption, and data whitening/dewhitening.

Integrated Radio Transceiver
The CYBT-4230xx-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-4230xx-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-4230xx-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-4230xx-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-4230xx-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-4230xx-02 uses an internal loop filter.

Microcontroller Unit
The CYBT-4230xx-02 includes a Arm Cortex-M4 processor with 2 MB of ROM, 448 KB of data RAM, 64 KB of patch RAM, and 1 MB of on-chip flash. The CM4 has a maximum speed of 96 MHz. CYBT-4230xx-02 supports execution from on-chip flash (OCF). The CM4 also includes a single precision IEEE 754 compliant floating point unit (FPU). The CM4 runs all the BT layers as well as application code. The ROM includes LM, HCI, L2CAP, GATT, as well as other stack layers freeing up the flash for application usage. A standard serial wire debug (SWD) interface provides debugging support. External Reset An external active-low reset signal, XRES, can be used to put the CYBT-4230xx-02 in the reset state. An external voltage detector reset IC with 50 ms delay is recommended on the XRES connection. The XRES must only be released after the VDDO supply voltage level has been stabilized for 50 ms.

Peripheral and Communication Interfaces
I2C The CYBT-4230xx-02 provides a 2-pin I2C compatible master interface to communicate with I2C compatible peripherals. The following transfer clock rates are supported:  100 kHz  400 kHz  800 kHz (Not a standard I2C-compatible speed)  1 MHz (Compatibility with high-speed I2C-compatible devices is not guaranteed) SCL and SDA lines can be routed to any of the P0-P39 GPIOs allowing for flexible system configuration. When used as SCL/SDA, the GPIOs go into open drain mode and require an external pull-up for proper operation. I2C block does not support multi master capability by either master or slave devices. I2C is Master Only. HCI UART Interface The CYBT-4230xx-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 1.5 Mbps. Typical rates are 115200, 921600, 1500000 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-4230xx-02 UART operates correctly with the host UART as long as the combined baud rate error of the two devices is within ±5%. The UART interface 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-4230xx-02 can wake up the host as needed or allow the host to sleep via the HOST_WAKE signal (solder pad 2). Signal allows the CYBT-4230xx-02 to optimize system power consumption by allowing a host device to remain in low power modes as long as possible. The HOST_WAKE signal can be enabled via a vendor specific command. Peripheral UART Interface The CYBT-4230xx-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-4230xx-02 can map the peripheral UART to any GPIO. The Peripheral UART functionality is the same as the HCI UART, but with a 256-byte transmit and receive FIFO. Serial Peripheral Interface The CYBT-4230xx-02 has two independent SPI interfaces. Both interfaces support Single, Dual, and Quad mode SPI operations as well as MIPI DBI-C Interface. Either of the interface can be a master or a slave. SPI2 can support only one slave. SPI1 has a 1024 byte transmit and receive buffers which is shared with the host UART interface. SPI2 has a dedicated 256 byte transmit and receive buffers. To support more flexibility for user applications, the CYBT-4230xx-02 has optional I/O ports that can be configured individually and separately for each functional pin. SPI IO voltage depends on VDDO. MIPI Interface There are three options in DBI type-C corresponding to 9-bit, 16-bit, and 8-bit modes. The CYBT-4230xx-02 plays the role of host, and only the 9-bit and 8-bit modes (option 1 and option 3 in DBI-C spec) are supported. In the 9-bit mode, the SCL, CS, MOSI, and MISO pins are used. In the 8-bit mode, an additional pin (DCX) is required. The DCX pin indicates if the current outgoing bit stream is a command or data byte.

32 kHz Crystal Oscillator The CYBT-4230xx-02 utilizes the built-in Local Oscillator (LO) on the CYW20719/21 silicon device for 32 kHz timing. The accuracy of the LO is +/- 500 ppm. The use of an external XTAL oscillator is optional. CYBT-4230xx-02 includes external XTAL oscillator connections for applications requiring higher timing accuracy. Figure 12 shows an external 32 kHz XTAL oscillator with external components and Table 9 lists the recommended external oscillator's characteristics. This oscillator input can be operated with a 32 kHz or 32.768 kHz crystal oscillator or be driven with a clock input at similar frequency. The default component values are: R1 = 10 M and C1 = C2 = ~6 pF. The values of C1 and C2 are used to fine-tune the oscillator.

PDM Microphone The CYBT-4230xx-02 accepts a -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 PDM input 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-4230xx-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. Note Subject to the driver support in WICED Studio. I2S Interface The CYBT-4230xx-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  I2S Data In: I2S DI I2S 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-4230xx-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.
PCM Interface The CYBT-4230xx-02 includes a PCM interface that can connect to linear PCM codec devices in master or slave mode. In master mode, the CYBT-4230xx-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-4230xx-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-4230xx-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-4230xx-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-4230xx-02 may be configured to generate and accept several different data formats. For conventional narrow band speech mode, the CYBT-4230xx-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-4230xx-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. This 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) Note Security Engine is used only by the Bluetooth stack to reduce CPU overhead. It is not available for application use. 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.

The CYBT-4230xx-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.  Sleep mode - In this mode, CPU is in WFI and the HCLK is not running. The PMU determines if the other clocks can be turned off
and does accordingly. State of the entire chip is retained, the internal LDOs run at a lower voltage (voltage is managed by the PMU), and SRAM is retained.  PDS mode - This 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 paused.  Shut Down Sleep (SDS) - Everything is turned off except the IO Power Domain, RTC, and LPO. The device can come out of this mode either due to BT activity or by an external interrupt. Before going into this mode, the application can store some bytes of data into "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, Bluetooth LE connection, or Bluetooth LE 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 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.  HIDOFF (External Interrupt-Waked) mode - This mode is similar to Timed-Wake, but in HID-off mode even the LPO and RTC are turned off. So, the only wakeup source is an external interrupt. Transition between power modes is handled by the on-chip firmware with host/application involvement. See the Firmware Section for details.
Firmware
The CYBT-4230xx-02 ROM firmware runs on a real time operating system and handles the programming and configuration of all on-chip hardware functions as well as the BT/LE baseband, LM, HCI, GATT, ATT, L2CAP and SDP layers. The ROM also includes drivers for on-chip peripherals as well as handling on-chip power management functions including transitions between different power modes. The CYBT-4230xx-02 is fully supported by the Cypress WICED Studio platform. WICED releases provide latest ROM patches, drivers, and sample applications allowing customized applications using the CYBT-4230xx-02 to be built quickly and efficiently. Refer to WICED Technical Brief and CYBT-4230xx-02 Product Guide for details on the firmware architecture, driver documentation, power modes and how to write applications/profiles using the CYBT-4230xx-02.
