Functional Description 1.1 Integrated Radio Transceiver The CYW20733 has an integrated radio transceiver that has been optimized for use in 2.4 GHz Bluetooth wireless systems. It has been designed to provide low power, low cost, robust communications for applications operating in the globally available 2.4 GHz unlicensed ISM band. It is fully compliant with Bluetooth Radio Specification 3.0 + EDR and meets or exceeds the requirements to provide the highest communication link quality of service. 1.1.1 Transmitter Path The CYW20733 features a fully integrated zero IF transmitter. The baseband transmit data is GFSK modulated in the modem block and upconverted to the 2.4 GHz ISM band. The transmit path consists of signal filtering, I/Q upconversion, output power amplification, and RF filtering. It also incorporates the /4-DQPSK and 8-DPSK modulation schemes, which support the 2 Mbps and 3 Mbps enhanced data rates, respectively. Digital Modulator The digital modulator performs the data modulation and filtering required for the GFSK, /4-DQPSK, and 8-DPSK signals. The fully digital modulator minimizes any frequency drift or anomalies in the modulation characteristics of the transmitted signal and is much more stable than direct VCO modulation schemes. Power Amplifier The integrated power amplifier (PA) for the CYW20733 can transmit at a maximum power of +4 dBm for class 2 operation. The transmit power levels are for basic rate and EDR. Due to the linear nature of the PA, combined with some integrated filtering, no external filters are required for meeting Bluetooth and regulatory harmonic and spurious requirements. The CYW20733 internal PA can deliver a maximum output power of +10 dBm for basic rate and +8 dBm for EDR with a flexible supply range of 2.5V to 3.0V. 1.1.2 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, an extended dynamic range, and high-order on-chip channel filtering to ensure reliable operation in the noisy 2.4 GHz ISM band. The front-end topology with built-in out-of-band attenuation enables the CYW20733 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 CYW20733 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. 1.1.3 Local Oscillator The local oscillator (LO) provides fast frequency hopping (1600 hops/second) across the 79 maximum available channels. The LO subblock employs an architecture for high immunity to LO pulling during PA operation. The CYW20733 uses an internal RF and IF loop filter. 1.1.4 Calibration The CYW20733 radio transceiver features an automated calibration scheme that is self-contained in the radio. No user interaction is required during normal operation or during manufacturing to provide the optimal performance. Calibration will optimize the gain and phase performance of all the major blocks within the radio to within 2% of optimal conditions. Calibrated blocks include filters, the matching networks between key components, and key gain blocks. The calibration process corrects for both process and temperature variations. It occurs transparently during normal operation and the setting time of the hops and will calibrate for temperature variations as the device cools and heats during normal operation in its environment. 1.1.5 Internal LDO Regulator To reduce the external BOM, the CYW20733 has an integrated 1.2V LDO regulator to provide power to the digital and RF circuits and system components. The 1.2V LDO regulator operates from a 1.62V to 3.63V input supply with a 60 mA maximum load current. In noisy environments, a ferrite bead may be needed between the digital and RF supply pins to isolate noise coupling and suppress noise into the RF circuits. Note: Always place the decoupling capacitors near the pins as close together as possible.

The microprocessor is based on an ARM7™ 32-bit RISC processor with embedded ICE-RT debug and JTAG interface units. The µPU has 320 KB of ROM for program storage and boot-up, 80 KB of RAM for scratch-pad data, and patch RAM code. The internal boot ROM allows for flexibility during power-on reset to enable the same device to be used in various configurations, including UART, and with an external serial EEPROM or with an external flash memory. At power-up, the lower layer protocol stack is executed from the internal ROM memory. External patches may be applied to the ROM-based firmware to provide flexibility for bug fixes and feature additions. The device can also support the integration of user applications. 1.2.1 EEPROM Interface The CYW20733 provides the BSC (Broadcom Serial Control) master interface; the BSC is programmed by the CPU to generate four different types of BSC transfers on the bus: read-only, write-only, combined read/write, and combined write/read. BSC supports both low-speed and fast mode devices. The BSC is compatible with a Philips® I2C slave device, except that master arbitration (multiple I2C masters contending for the bus) is not supported. Native support for Microchip® 24LC128, Microchip 24AA128, and STMicroelectronics® M24128-BR is included. The EEPROM can contain customer application configuration information, including: application code, configuration data, patches, pairing information, BD_ADDR, baud rate, SDP service record, and file system information used for code. 1.2.2 Serial Flash Interface The CYW20733 includes an SPI master controller that can be used to access serial flash memory. The SPI master contains an AHB slave interface, transmit and receive FIFOs, and the SPI core PHY logic. Devices natively supported include the following: ■ Atmel® AT25BCM512B ■ MXIC MX25V512ZUI-20G 1.2.3 Internal Reset The CYW20733 has an integrated power-on reset circuit that resets all circuits to a known power-on state.

The RESET_N pin has an internal pull-up resistor and, in most applications, it does not require that anything be connected to it. RESET_N should only be released after the VDDO supply voltage level has been stabilized. Figure 2.

Crystal Enable 1.3 Bluetooth Baseband Core The Bluetooth Baseband Core (BBC) implements all of the time-critical functions required for high-performance Bluetooth operation. The BBC manages the buffering, segmentation, and routing of data for all connections. It also buffers data that passes through it, handles data flow control, schedules ACL TX/RX transactions, monitors Bluetooth slot usage, optimally segments and packages data into baseband packets, manages connection status indicators, and composes and decodes HCI packets. In addition to these functions, it independently handles HCI event types and HCI command types. The following transmit and receive functions are also implemented in the BBC hardware to increase reliability and security of the TX/ RX data before sending over the air: ■ Receive Functions: Symbol timing recovery, data deframing, forward error correction (FEC), header error control (HEC), cyclic redundancy check (CRC), data decryption, and data de-whitening. ■ Transmit Functions: Data framing, FEC generation, HEC generation, CRC generation, link key generation, data encryption, and data whitening. 1.3.1 Frequency Hopping Generator The frequency hopping sequence generator selects the correct hopping channel number depending on the link controller state, Bluetooth clock, and the device address. 1.3.2 E0 Encryption The encryption key and the encryption engine are implemented using dedicated hardware to reduce software complexity and provide minimal intervention. 1.3.3 Link Control Layer The Link Control layer is part of the Bluetooth link control functions that are implemented in dedicated logic in the Link Control Unit (LCU). This layer consists of the command controller, which takes commands from the software, and other controllers that are activated or configured by the command controller to perform the link control tasks. Each task performs in a different state in the Bluetooth link controller. STANDBY and CONNECTION are the two major states. In addition, there are five substates: page, page scan, inquiry, inquiry scan, and sniff. 1.3.4 Adaptive Frequency Hopping The CYW20733 gathers link quality statistics on a channel-by-channel basis to facilitate channel assessment and channel map selection. The link quality is determined using both RF and baseband signal processing to provide a more accurate frequency-hop map. 1.3.5 Bluetooth Version 3.0 Features The CYW20733 is fully compliant with the Bluetooth 3.0 standard, including the following options: Document No. 002-14859 Rev. *S Page 6 of 67 CYW20733 ■ Enhanced power control ■ HCI read, encryption key size command The CYW20733 supports all of the new Bluetooth version 2.1 features: ■ Extended inquiry response ■ Sniff subrating ■ Encryption pause and resume ■ Secure simple pairing ■ Link supervision timeout changed event ■ Erroneous data reporting ■ Non-automatically flushable packet boundary flag ■ Security Mode 4 1.3.6 Test Mode Support The CYW20733 fully supports Bluetooth Test Mode, as described in Part 1 of the Bluetooth System Version 2.1 specification. This includes the transmitter tests, normal and delayed loopback tests, and reduced hopping sequence. In addition to the standard Bluetooth test mode, the device supports enhanced testing features to simplify RF debugging and qualification and type approval testing. These features include: ■ Fixed frequency carrier wave (unmodulated) transmission ■ Simplified type approval measurements (Japan) ■ Aid in transmitter performance analysis ■ Fixed frequency constant receiver mode ■ Receiver output directed to I/O pin ■ Direct BER measurements using standard RF test equipment ■ Facilitated spurious emissions testing for receive mode ■ Fixed frequency constant transmission ■ 8-bit fixed pattern or PRBS-9 ■ Modulated signal measurements with standard RF test equipment ■ Connectionless transmitter test ■ Hopping or fixed frequency ■ Multiple packet types ■ Multiple data patterns ■ Connectionless receiver test 1.4 Peripheral Transport Unit (PTU) 1.4.1 Broadcom Serial Control Interface The CYW20733 provides a 2-pin master BSC interface that can be used to retrieve configuration information from an external EEPROM or to communicate with peripherals such as track-ball or touch-pad modules, and motion tracking ICs used in mouse devices. The BSC interface is compatible with I2C slave devices. The BSC does not support multimaster capability or flexible waitstate insertion by either master or slave devices. Listed below are the transfer clock rates supported by the BSC: ■ 100 kHz ■ 400 kHz ■ 800 kHz (Not a standard I2C-compatible speed.) Document No. 002-14859 Rev. *S Page 7 of 67 CYW20733 ■ 4 MHz maximum (Compatibility with high-speed I2C-compatible devices is not guaranteed.) The following transfer types are supported by the BSC: ■ Read (up to 127 bytes can be read) ■ Write (up to 127 bytes can be written) ■ Read-then-Write (Up to 127 bytes can be read, and up to 127 bytes can be written.) ■ Write-then-Read (Up to 127 bytes can be written, and up to 127 bytes can be read.) Hardware controls the transfers, requiring minimal firmware setup and supervision. The clock pin (SCL) and data pin (SDA) are both open-drain I/O pins. Pull-up resistors external to the CYW20733 are required on both SCL and SDA for proper operation. 1.4.2 UART Interface The UART physical interface is a standard, 4-wire interface (RX, TX, RTS, and CTS) with adjustable baud rates from 9600 bps to 1.5 Mbps. During initial boot, UART speeds may be limited to 750 kbps. The baud rate may be selected via a vendor-specific UART HCI command. The CYW20733 has a 1040-byte receive FIFO and a 1040-byte transmit FIFO to support enhanced data rates. The interface supports the Bluetooth 3.0 UART HCI (H4) specification. The default baud rate for H4 is 115.2 kbaud. The UART clock is 24 MHz. The baud rate of the CYW20733 UART is controlled by two values. The first is a UART clock divisor (also called the DLBR register) that divides the UART clock by an integer multiple of 16. The second is a baud rate adjustment (also called the DHBR register) that is used to specify a number of UART clock cycles to stuff in the first or second half of each bit time. Up to eight UART cycles can be inserted into the first half of each bit time, and up to eight UART clock cycles can be inserted into the end of each bit time. When setting the baud rate manually, the UART clock divisor is an 8-bit value that is stored as 256 minus the chosen divisor. For example, a divisor of 13 is stored as 256 – 13 = 243 = 0xF3. The baud rate adjustment is also an 8-bit value, of which the four MSBs are the number of additional clock cycles to insert in the first half of each bit time, and the four LSBs are the number of clock cycles to insert in the second half of each bit time. If either of these two values is over eight, it is rounded to eight. To compute the baud rate, the calculation is expressed as: 24 MHz ÷ ((16 × UART clock divisor) + total inserted 24-MHz clock cycles) Table 2 contains example values to generate common baud rates.

Support for changing the baud rate during normal HCI UART operation is included through a vendor-specific command that allows the host to adjust the contents of the baud rate registers. The CYW20733 UART operates correctly with the host UART as long as the combined baud rate error of the two devices is within ±5%. Peripheral UART Interface The CYW20733 has a second UART that may be used to interface to other peripherals. This peripheral UART is accessed through the optional I/O ports, which can be configured individually and separately for each functional pin as shown in Table 3.

In master mode, the device generates the PCM_BCLK and PCM_SYNC signals. In slave mode, these signals are provided by another master on the PCM interface as inputs to the device. The channels can be configured to either transmit or receive, but they must be assigned to different time slots. The two half-duplex channels cannot be combined to form a single full-duplex channel. 1.5.1 System Diagram Figure 3 shows options for connecting the device to a PCM codec device as a master or a slave.

PCM Interface Time-Slotting Scheme Audio Sample Rate Time-Slotting Scheme 8 kHz The number of slots depends on the selected interface rate, as follows: Interface rate Slot 1281 2562 5124 10248 204816 16 kHz The number of slots depends on the selected interface rate, as follows: Interface rate Slot 2561 5122 10244 20488 The PCM data output driver tri-states 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. 1.5.3 Frame Synchronization The device supports both short and long frame synchronization types in both master and slave configurations. In short frame synchronization mode, the frame synchronization signal is an active-high pulse at the 8 kHz audio frame rate (which is a single bit period in width) and synchronized to the rising edge of the bit clock. The PCM slave expects PCM_SYNC to be high on the falling edge of the bit clock and the first bit of the first slot to start at the next rising edge of the clock. In the long frame synchronization mode, the frame synchronization signal is an active-high pulse at the 8 kHz audio frame rate. However, the duration is 3-bit periods, and the pulse starts coincident with the first bit of the first slot. 1.5.4 Data Formatting The device can be configured to generate and accept several different data formats. The device uses 13 of the 16 bits in each PCM frame. The location and order of these 13 bits is configurable to support various data formats on the PCM interface. The remaining three bits are ignored on the input and may be filled with zeros, ones, a sign bit, or a programmed value on the output. The default format is 13-bit two’s complement data, left justified, and clocked most significant bit first. 1.6 I2S Interface The I2S interface supports up to two half-duplex channels. The channels can be configured to either transmit or receive, but they must be assigned to different time slots (left or right). The two half-duplex channels cannot be combined to form a single full-duplex channel. The I2S interface is capable of operating in either slave or master mode. The device supports a 16-bit data width with 8-kHz and 16kHz frame rates. 1.7 Clock Frequencies The CYW20733 is set with a crystal frequency of 24 MHz. 1.7.1 Crystal Oscillator The crystal oscillator requires a crystal with an accuracy of ±20 ppm as defined by the Bluetooth specification. Two external load capacitors in the 5 pF to 30 pF range are required to work with the crystal oscillator. The selection of the load capacitors is crystal dependent. Table 5 shows the recommended crystal specification. Document No. 002-14859 Rev. *S Page 10 of 67 CYW20733 Figure 4. Recommended Oscillator Configuration—12 pF Load Crystal Table 5.

The oscillator can be turned on at the request of any of the peripherals. If a peripheral is not enabled, it shall not assert its clock request line. The keyboard scanner is a special case in that it may drop its clock request line even when enabled and then reassert the clock request line if a key-press is detected. Real-Time Clock and 32 kHz Crystal Oscillator The CYW20733 has a 48-bit counter that can be configured to be clocked directly from a 32.768 kHz or 32.000 kHz crystal oscillator. The real-time clock counter value is accessible via firmware. Figure 5 shows the 32 kHz crystal (XTAL) oscillator with external components, and Table 6 lists the oscillator’s characteristics. It is a standard Pierce oscillator using a comparator with hysteresis on the output to create a single-ended digital output. The hysteresis was added to eliminate any chatter when the input is around the threshold of the comparator and is ~100 mV. This circuit can be operated with a 32 kHz or 32.768 kHz crystal oscillator or be driven with a clock input at a similar frequency. The default component values are: R1 = 10 M, C1 = C2 = ~10 pF. The values of C1 and C2 are used to fine-tune the oscillator. Document No. 002-14859 Rev. *S Page 11 of 67 CYW20733 Figure 5. 32-kHz Oscillator Block Diagram C2 32.768 kHz XTAL R1 C1 Table 6.

All GPIOs support programmable pull-ups and are capable of driving up to 8 mA at 3.3V or 4 mA at 1.8V, except P26, P27, P28, and P29, which are capable of driving up to 16 mA at 3.3V or 8 mA at 1.8V. GPIO P57 is capable of sinking 100 mA for VDDIO = 3.0V and 60 mA for VDDIO = 1.62V. Port 0–Port 1, Port 8–Port 18, Port 20–Port 23, and Port 28–Port 38 All of these pins can be programmed as ADC inputs. Port 26–Port 29 P[26:29] consist of four pins. All pins are capable of sinking up to 16 mA for LEDs. These pins also have the PWM function, which can be used for LED dimming. 1.9 Keyboard Scanner The keyboard scanner is designed to autonomously sample keys and store them into buffer registers without the need for the host microcontroller to intervene. The scanner has the following features: ■ Ability to turn off its clock if no keys are pressed. ■ Sequential scanning of up to 160 keys in an 8 × 20 matrix. ■ Programmable number of columns from 1 to 20. ■ Programmable number of rows from 1 to 8. ■ 16-byte key-code buffer (can be augmented by firmware). ■ 128 kHz clock—allows scanning of full 160-key matrix in about 1.2 ms. ■ N-key rollover with selective 2-key lockout if ghost is detected. ■ Keys are buffered until host microcontroller has a chance to read it, or until overflow occurs. Document No. 002-14859 Rev. *S Page 12 of 67 CYW20733 ■ Hardware debouncing and noise/glitch filtering. ■ Low-power consumption. Single-digit µA-level sleep current. 1.9.1 Theory of Operation The key scan block is controlled by a state machine with the following states: Idle The state machine begins in the idle state. In this state, all column outputs are driven high. If any key is pressed, a transition occurs on one of the row inputs. This transition causes the 128 kHz clock to be enabled (if it is not already enabled by another peripheral) and the state machine to enter the scan state. Also in this state, an 8-bit row-hit register and an 8-bit key-index counter is reset to 0. Scan In the scan state, a row counter counts from 0 up to a programmable number of rows minus 1. After the last row is reached, the row counter is reset and the column counter is incremented. This cycle repeats until the row and column counters are both at their respective terminal count values. At that point, the state machine moves into the Scan-End state. As the keys are being scanned, the key-index counter is incremented. This counter is the value compared to the modifier key codes stored, or in the key-code buffer if the key is not a modifier key. It can be used by the microprocessor as an index into a lookup table of usage codes. Also, as the nth row is scanned, the row-hit register is ORed with the current 8-bit row input values if the current column contains two or more row hits. During the scan of any column, if a key is detected at the current row, and the row-hit register indicates that a hit was detected in that same row on a previous column, then a ghost condition may have occurred, and a bit in the status register is set to indicate this. Scan End This state determines whether any keys were detected while in the scan state. If yes, the state machine returns to the scan state. If no, the state machine returns to the idle state, and the 128 kHz clock request signal is made inactive. The microcontroller can poll the key status register. 1.10 Mouse Quadrature Signal Decoder The mouse signal decoder is designed to autonomously sample two quadrature signals commonly generated by an optomechanical mouse. The decoder has the following features: ■ Three pairs of inputs for X, Y, and Z (typical scroll wheel) axis signals. Each axis has two options: For the X axis, choose P2 or P32 as X0 and P3 or P33 as X1. ❐ For the Y axis, choose P4 or P34 as Y0 and P5 or P35 as Y1. ❐ For the Z axis, choose P6 or P36 as Z0 and P7 or P37 as Z1. ❐ ■ Control of up to four external high-current GPIOs to power external optoelectronics: Turn-on and turn-off time can be staggered for each HC-GPIO to avoid simultaneous switching of high currents and having multiple high-current devices on at the same time. ❐ Sample time can be staggered for each axis. ❐ Sense of the control signal can be active high or active low. ❐ Control signal can be tristated for off condition or driven high or low, as appropriate. ❐ 1.10.1 Theory of Operation The mouse decoder block has four 10-bit PWMs for controlling external quadrature devices and sampling the quadrature inputs at its core. The GPIO signals may be used to control such items as LEDs, external ICs that may emulate quadrature signals, photodiodes, and photodetectors. 1.11 ADC Port The CYW20733 contains a 16-bit ADC. Additionally: ■ There are 28 analog input channels. All channels are multiplexed on various GPIOs. ■ There is a built-in reference with bandgap-based reference modes. ■ The maximum conversion rate is 187 kHz. ■ There is a rail-to-rail input swing. Document No. 002-14859 Rev. *S Page 13 of 67 CYW20733 The ADC consists of an analog ADC core that performs the actual analog-to-digital conversion and digital hardware that processes the output of the ADC core into valid ADC output samples. Directed by the firmware, the digital hardware also controls the input multiplexers that select the ADC input signal (Vinp) and the ADC reference signals (Vref). Table 7.

One is a master-only interface (SPI_1) and the other (SPI_2) can be either a master or a slave. Each interface has a 64-byte transmit buffer and a 64-byte receive buffer. To support more flexibility for user applications, the CYW20733 has optional I/O ports that can be configured individually and separately for each functional pin, as shown in Table 8. The CYW20733 acts as an SPI master device that supports 1.8V or 3.3V SPI slaves. The CYW20733 can also act as an SPI slave device that supports a 1.8V or 3.3V SPI master. Note: SPI voltage depends on VDDO/VDDM; therefore, it defines the type of devices that can be supported. Table 8.

The hardware can transmit both modulated and unmodulated waveforms. For modulated waveforms, hardware inserts the desired carrier frequency into all IR transmissions. IR TX can be sourced from firmware-supplied descriptors, a programmable bit, or the peripheral UART transmitter. If descriptors are used, they include IR on/off state and the duration between 1–32767 µsec. The CYW20733 IR TX firmware driver inserts this information in a hardware FIFO and makes sure that all descriptors are played out without an underrun glitch. See Figure 7. Document No. 002-14859 Rev. *S Page 18 of 67 CYW20733 Figure 7. Infrared TX VCC R1 Infrared‐LD D1 U1 CYW20733 R2 Q1 IR TX 1.15 Infrared Learning The CYW20733 includes hardware support for infrared learning. The hardware can detect both modulated and unmodulated signals. For modulated signals, the CYW20733 can detect carrier frequencies between 10–500 kHz and the duration that the signal is present or absent. The CYW20733 firmware driver supports further analysis and compression of a learned signal. A learned signal can then be played back through the CYW20733 IR TX subsystem. See Figure 8. Figure 8. Infrared RX VCC U3 CYW20733 D2 Photodiode IR RX 1.16 Shutter Control for 3D Glasses The CYW20733, combined with the CYW20702, provides full system support for 3D glasses on televisions. The CYW20702 gets frame synchronization signals from the TV, converts them into proprietary timing control messages, then passes the messages to the CYW20733. The CYW20733 uses these messages to synchronize the shutter control for the 3D glasses with the television frames. Document No. 002-14859 Rev. *S Page 19 of 67 CYW20733 The CYW20733 can provide up to four synchronized control signals for left and right eye shutter control. These four lines can output pulses with microsecond resolution for on and off timing. The total cycle time can be set for any period up to 65535 msec. The pulses are synchronized to each other for left and right eye shutters. The CYW20733 seamlessly adjusts the timing of the control signals based on control messages from the CYW20702, ensuring that the 3D glasses remain synchronized to the TV display frame. 3D hardware control on the CYW20733 works independently of the rest of the system. The CYW20733 negotiates sniff with the CYW20702 and, except for sniff resynchronization periods, most of the CYW20733 circuitry remains in a low power state while the 3D glasses subsystem continues to provide shutter timing and control pulses. This significantly reduces total system power consumption. 1.17 Triac Control The CYW20733 includes hardware support for zero-crossing detection and trigger control for up to four triacs. The CYW20733 detects zero-crossing on the AC zero detection line and uses that to provide a pulse that is offset from the zero crossing. This allows the CYW20733 to be used in dimmer applications, as well as any other applications that require a control signal that is offset from an input event. The zero-crossing hardware includes an option to suppress glitches. See Figure . Figure 9. Triac Control (TBD) 1.18 Cypress Proprietary Control Signalling and Triggered Broadcom Fast Connect Cypress Proprietary Control Signaling (BPCS) and Triggered Broadcom Fast Connect (TBFC) are Cypress-proprietary baseband (ACL) suspension and low-latency reconnection mechanisms that reestablish the baseband connection with the peer controller that also supports BPCS/TBFC. The CYW20733 uses BPCS primitives to allow a Human Interface Device (HID) to suspend all RF traffic after a configurable idle period with no reportable activity. To conserve power, it can then enter one of its low power states while still logically remaining connected at the L2CAP and HID layers with the peer device. When an event requires the HID to deliver a report to the peer device, the CYW20733 uses the TBFC and BPCS mechanisms to reestablish the baseband connection and immediately resume L2CAP traffic, greatly reducing latency between the event and delivery of the report to the peer device. To achieve power savings and low latencies that cannot be achieved using long sniff intervals, certain applications may make use of the CYW20733 Broadcom Fast Connect (BFC) mechanism, which will eliminate the need to maintain an RF link, while still being able to establish ACL and L2CAP connections much faster than regular methods. 1.19 Integrated Filterless Class-D Audio Amplifier The CYW20733 has an integrated speaker driver that includes both the digital path and an internal audio amplifier. The digital audio path includes a FIFO, LPF, rate adapter, and PWM modulator. The output of the PWM modulator drives an on-chip class-D high efficiency audio amplifier as shown in the figure below.

M = 160 or 320 AP Interface 3 The on-chip Class-D audio amplifier is designed to drive up to 200 mW into an 8 load and has a range of 20 Hz to 20 kHz, covering the entire audio spectrum. The amplifier is designed to deliver maximum dynamic range and power efficiency while minimizing quiescent current. The amplifier has two nonoverlapping switch drivers and a pair of MOSFET power switches for bridge-tie load. The digital Class-D modulator converts the audio input to a PWM signal that drives the switch driver. The modulator bitstream is retimed by a low-jitter 24/48 MHz clock at the input of the nonoverlapping switch drivers, used to prevent large crowbar currents during switching. A large W/L aspect ratio of the power transistor is used to minimize the on-resistance of the devices for improved efficiency. The integrated audio amplifier requires a 3.0V regulated power supply. The required LDO characteristic is shown in Table 11. Table 11.

For VDDIO = 1.62V, GPIO P57 is limited to sinking up to 60 mA. This pin can be used for LEDs, motors, or other high current devices. This pin can also be used as a GPIO if high current sink capability is not required. An example usage for driving a motor/vibrator is shown in Figure 11.

As a power-saving task, the firmware controls the disabling of the on-chip regulator when in Deep-sleep mode. 1.21.3 BBC Power Management There are several low-power operations for the BBC: ■ Physical layer packet handling turns RF on and off dynamically within packet TX and RX. ■ Bluetooth-specified low-power connection sniff mode. While in these low-power connection modes, the CYW20733 runs on the Low-Power Oscillator (LPO) and wakes up after a predefined time period. The CYW20733 automatically adjusts its power dissipation based on user activity. The following power modes are supported: ■ Active mode ■ Idle mode ■ Suspend mode ■ Power-down mode ■ HIDOFF mode The CYW20733 transitions to the next lower state after a programmable period of user inactivity. Busy mode is immediately entered when user activity resumes. HIDOFF mode is one of the power modes in which the core is powered down and only supervisory circuits running directly from the battery retain power.
