Functional Description 1.1 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 SCO/ACL and 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: Symbol timing recovery, data deframing, forward error correction (FEC), header error control (HEC), cyclic redundancy check (CRC), data decryption, and data dewhitening in the receiver. Data framing, FEC generation, HEC generation, CRC generation, key generation, data encryption, and data whitening in the transmitter. 1.1.1 Bluetooth 4.2 Features Both the CYW20706 36-pin WLBGA package and the 49-pin FBGA package support all Bluetooth 4.2 and legacy features, with the following benefits: Dual-mode Bluetooth low energy (BT and BLE operation) Extended inquiry response (EIR): Shortens the time to retrieve the device name, specific profile, and operating mode. Encryption pause resume (EPR): Enables the use of Bluetooth technology in a much more secure environment. Sniff subrating (SSR): Optimizes power consumption for low duty cycle asymmetric data flow, which subsequently extends battery life. Secure simple pairing (SSP): Reduces the number of steps for connecting two devices, with minimal or no user interaction required. Link supervision time out (LSTO): Additional commands added to HCI and Link Management Protocol (LMP) for improved link timeout supervision. Quality of service (QoS) enhancements: Changes to data traffic control, which results in better link performance. Audio, human interface device (HID), bulk traffic, SCO, and enhanced SCO (eSCO) are improved with the erroneous data (ED) and packet boundary flag (PBF) enhancements.

This layer consists of the command controller that 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 is performed in a different state in the Bluetooth Link Controller. States: Standby Connection Page Page Scan Inquiry Inquiry Scan Sniff Advertising Scanning 1.1.3 Test Mode Support The CYW20706 fully supports Bluetooth Test mode as described in Part I:1 of the Specification of the Bluetooth System Version 3.0. This includes the transmitter tests, normal and delayed loopback tests, and reduced hopping sequence. In addition to the standard Bluetooth Test Mode, the CYW20706 also supports enhanced testing features to simplify RF debugging and qualification and type-approval testing. These features include: Fixed frequency carrier wave (unmodulated) transmission Fixed frequency constant receiver mode Simplifies some type-approval measurements (Japan) Aids in transmitter performance analysis Receiver output directed to I/O pin Allows for direct BER measurements using standard RF test equipment Facilitates spurious emissions testing for receive mode Fixed frequency constant transmission 8-bit fixed pattern or PRBS-9 Enables modulated signal measurements with standard RF test equipment 1.1.4 Frequency Hopping Generator The frequency hopping sequence generator selects the correct hopping channel number based on the link controller state, Bluetooth clock, and device address. Document Number: 002-19479 Rev. ** Page 5 of 47 PRELIMINARY CYW20706 1.2 Microprocessor Unit The CYW20706 microprocessor unit runs software from the link control (LC) layer up to the host controller interface (HCI). The microprocessor is based on the Cortex-M3 32-bit RISC processor with embedded ICE-RT debug and JTAG interface units. The microprocessor also includes 848 KB of ROM memory for program storage and boot ROM, 352 KB of RAM for data scratch-pad, and patch RAM code. The internal boot ROM provides flexibility during power-on reset to enable the same device to be used in various configurations. At power-up, the lower layer protocol stack is executed from the internal ROM. External patches can be applied to the ROM-based firmware to provide flexibility for bug fixes and features additions. These patches can be downloaded using external NVRAM. The device can also support the integration of user applications and profiles using an external serial flash memory. 1.2.1 NVRAM Configuration Data and Storage NVRAM contains configuration information about the customer application, including the following: Fractional-N information BD_ADDR UART baud rate SDP service record File system information used for code, code patches, or data. The CYW20706 can use SPI Flash or I2C EEPROM/serial flash for NVRAM storage. 1.2.2 One-Time Programmable Memory The CYW20706 includes 2 Kbytes of one-time programmable (OTP) memory allow manufacturing customization and to avoid the need for an on-board NVRAM. If customization is not required, then the OTP does not need to be programmed. Whether the OTP is programmed or not, to save power it is disabled when the boot process is complete. The OTP is designed to store a minimal amount of information. Aside from OTP data, most user configuration information will be downloaded to RAM after the CYW20707 boots and is ready for host transport communication. The OTP contents are limited to: Parameters required prior to downloading the user configuration to RAM. Parameters unique to each part and each customer (for example, the Bluetooth device address and/or the software license key). Document Number: 002-19479 Rev. ** Page 6 of 47 PRELIMINARY CYW20706 1.2.3 External Reset An external active-low reset signal, RESET_N, can be used to put the CYW20706 in the reset state. An external voltage detector reset IC with 50 ms delay is needed on the RESET_N. The RESET_N should be released only after the VDDO supply voltage level has been stabilized for 50 ms. Figure 2. Reset Timing Low threshold 50 ms Reset (External) VDDO ~2.4 ms VDDO POR 0.5 ms VDDC ~2.4 ms VDDC Reset (Internal) 10 LPO cycles XTAL_RESET 8 LPO cycles XTAL_BUF_PU Note: The Reset signal should remain below this threshold 50 ms after VDDO is stable. Note that the representation of this signaling diagram is extended and not drawn to scale. Document Number: 002-19479 Rev. ** Page 7 of 47 PRELIMINARY CYW20706 1.3 Integrated Radio Transceiver The CYW20706 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. The CYW20706 is fully compliant with the Bluetooth Radio Specification and enhanced data rate (EDR) specification and meets or exceeds the requirements to provide the highest communication link quality of service. 1.3.1 Transmit The CYW20706 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 in the transmitter path. The transmitter path consists of signal filtering, I/Q upconversion, output power amplifier, and RF filtering. The transmitter path also incorporates /4-DQPSK for 2 Mbps and 8-DPSK for 3 Mbps to support EDR. The transmitter section is compatible with the BLE specification. The transmitter PA bias can also be adjusted to provide Bluetooth class 1 or class 2 operation. Digital Modulator The digital modulator performs the data modulation and filtering required for the GFSK, /4-DQPSK, and 8-DPSK signal. 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. 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. Power Amplifier The fully integrated PA supports Class 1 or Class 2 output using a highly linearized, temperature-compensated design. This provides greater flexibility in front-end matching and filtering. Due to the linear nature of the PA combined with some integrated filtering, external filtering is required to meet the Bluetooth and regulatory harmonic and spurious requirements. For integrated mobile handset applications in which Bluetooth is integrated next to the cellular radio, external filtering can be applied to achieve near thermal noise levels for spurious and radiated noise emissions. The transmitter features a sophisticated on-chip transmit signal strength indicator (TSSI) block to keep the absolute output power variation within a tight range across process, voltage, and temperature. 1.3.2 Receiver 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 CYW20706 to be used in most applications with minimal off-chip filtering. For integrated handset operation, in which the Bluetooth function is integrated close to the cellular transmitter, external filtering is required to eliminate the desensitization of the receiver by the cellular transmit signal. 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 CYW20706 provides a receiver signal strength indicator (RSSI) signal to the baseband, so that the controller can 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. 1.3.3 Local Oscillator Generation A local oscillator (LO) generation provides fast frequency hopping (1600 hops/second) across the 79 maximum available channels. The LO generation subblock employs an architecture for high immunity to LO pulling during PA operation. The CYW20706 uses an internal RF and IF loop filter. Document Number: 002-19479 Rev. ** Page 8 of 47 PRELIMINARY CYW20706 1.3.4 Calibration The CYW20706 radio transceiver features an automated calibration scheme that is fully self-contained in the radio. No user interaction is required during normal operation or during manufacturing to provide optimal performance. Calibration tunes the performance of all the major blocks within the radio to within 2% of optimal conditions, including gain and phase characteristics of filters, matching between key components, and key gain blocks. This takes into account process variation and temperature variation. Calibration occurs transparently during normal operation during the settling time of the hops, and calibrates for temperature variations as the device cools and heats during normal operation in its environment. 1.3.5 Internal LDO The CYW20706 uses two LDOs - one for 1.2V and the other for 2.5V. The 1.2V LDO provides power to the baseband and radio and the 2.5V LDO powers the PA. Figure 3.

Collaborative coexistence enables WLAN and Bluetooth to operate simultaneously in a single device. The device supports industry-standard coexistence signaling, including 802.15.2, and supports Cypress and third-party WLAN solutions. 1.5 Global Coexistence Interface The CYW20706 supports the proprietary Cypress Global Coexistence Interface (GCI) which is a 2-wire interface. The following key features are associated with the interface: Enhanced coexistence data can be exchanged over GCI_SECI_IN and GCI_SECI_OUT a two-wire interface, one serial input (GCI_SECI_IN), and one serial output (GCI_SECI_OUT). The pad configuration registers must be programmed to choose the digital I/O pins that serve the GCI_SECI_IN and GCI_SECI_OUT function. It supports generic UART communication between WLAN and Bluetooth devices. To conserve power, it is disabled when inactive. It supports automatic resynchronization upon waking from sleep mode. It supports a baud rate of up to 4 Mbps. 1.5.1 SECI I/O The CYW20706 devices have dedicated GCI_SECI_IN and GCI_SECI_OUT pins. The two pin functions can be mapped to any of the Cypress Global Coexistence Interface (GCI) GPIO. Pin function mapping is controlled by the configuration file that is stored in either NVRAM or downloaded directly into on-chip RAM from the host. Document Number: 002-19479 Rev. ** Page 9 of 47 PRELIMINARY CYW20706 1.6 Peripheral Transport Unit 1.6.1 Broadcom Serial Communications Interface The CYW20706 provides a 2-pin master BSC interface, which can be used to retrieve configuration information from an external EEPROM or to communicate with peripherals such as trackball or touch-pad modules, and motion tracking ICs used in mouse devices. The BSC interface is compatible with I2C slave devices. BSC does not support multimaster capability or flexible wait-state insertion by either master or slave devices. The following transfer clock rates are supported by BSC: 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 following transfer types are supported by 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 CYW20706 are required on both the SCL and SDA pins for proper operation. 1.6.2 UART Interface The UART physical interface is a standard, 4-wire interface (RX, TX, RTS, and CTS) with adjustable baud rates from 38400 bps to 6 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 CYW20706 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 UART clock default setting is 24 MHz, and can be configured to run as high as 48 MHz to support up to 6 Mbps. The baud rate of the CYW20706 UART is controlled by two values. The first is a UART clock divisor (set in the DLBR register) that divides the UART clock by an integer multiple of 16. The second is a baud rate adjustment (set in 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. Table 2 contains example values to generate common baud rates with a 24 MHz UART clock. Document Number: 002-19479 Rev. ** Page 10 of 47 PRELIMINARY CYW20706 Table 2.

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 CYW20706 UART operates correctly with the host UART as long as the combined baud rate error of the two devices is within 2%. Document Number: 002-19479 Rev. ** Page 11 of 47 PRELIMINARY CYW20706 Peripheral UART Interface The CYW20706 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 4. Table 4. CYW20706 Peripheral UART Pin Name Configured pin name pUART_TX pUART_RX pUART_CTS_N pUART_RTS_N P0 P2 P3 P6 P31 P33 - P30 1.7 PCM Interface The CYW20706 includes a PCM interface that shares pins with the I2S interface. The PCM Interface on the CYW20706 can connect to linear PCM codec devices in master or slave mode. In master mode, the CYW20706 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 CYW20706. 1.7.1 Slot Mapping The CYW20706 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. 1.7.2 Frame Synchronization The CYW20706 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 PCM 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. 1.7.3 Data Formatting The CYW20706 may be configured to generate and accept several different data formats. For conventional narrowband speech mode, the CYW20706 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. 1.7.4 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.

Other frequencies also supported by firmware configuration. Table 5 lists the strapping options. Table 5.

Two external load capacitors in the range of 5 pF to 30 pF are required to work with the crystal oscillator. The selection of the load capacitors is XTAL-dependent (see Figure 4). Figure 4.

The oscillator can be turned on at the request of any of the peripherals. If the 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 keypress is detected. 1.9 GPIO Ports 1.9.1 49-Pin FBGA Package The CYW20706 49-pin FBGA package has 24 general-purpose I/Os (GPIOs). 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.

Document Number: 002-19479 Rev. ** Page 14 of 47 PRELIMINARY CYW20706 1.10 PWM The CYW20706 has four internal PWMs. The PWM module consists of the following: PWM1-4 Each of the four PWM channels, PWM1-4, contains the following registers: 10-bit initial value register (read/write) 10-bit toggle register (read/write) 10-bit PWM counter value register (read) PWM configuration register shared among PWM1-4 (read/write). This 12-bit register is used: To configure each PWM channel To select the clock of each PWM channel To change the phase of each PWM channel Figure 5 shows the structure of one PWM. Figure 5.

The CYW20706 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 CYW20706 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. 1.12 Serial Peripheral Interface The CYW20706 has two independent SPI interfaces. One is a master-only interface (SPI_2) and the other (SPI_1) 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 CYW20706 has optional I/O ports that can be configured individually and separately for each functional pin. The CYW20706 acts as an SPI master device that supports 1.8V or 3.3V SPI slaves. The CYW20706 can also act as an SPI slave device that supports a 1.8V or 3.3V SPI master. Note: SPI voltage depends on VDDO; therefore, it defines the type of devices that can be supported. 1.13 Infrared Modulator The CYW20706 includes hardware support for infrared TX. 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 sec. The CYW20706 IR TX firmware driver inserts this information in a hardware FIFO and makes sure that all descriptors are played out without a glitch due to underrun (see Figure 6). Figure 6. Infrared TX VCC R1 62 D1 InfraredLD R2 CYW 20706 IR TX 2.4K Q1 M M BTA42 1.14 Infrared Learning The CYW20706 includes hardware support for infrared learning. The hardware can detect both modulated and unmodulated signals. For modulated signals, the CYW20706 can detect carrier frequencies between 10 kHz and 500 kHz, and the duration that the signal is present or absent. The CYW20706 firmware driver supports further analysis and compression of the learned signal. The learned signal can then be played back through the CYW20706 IR TX subsystem (see Figure 7). Figure 7.

As a power-saving task, the firmware controls the disabling of the on-chip regulator when in HIDOFF (deep sleep) mode. 1.15.3 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 mode. While in these low-power connection modes, the CYW20706 runs on the Low Power Oscillator and wakes up after a predefined time period. The CYW20706 automatically adjusts its power dissipation based on user activity. The following power modes are supported: Active mode Idle mode Sleep mode HIDOFF (deep sleep) mode The CYW20706 transitions to the next lower state after a programmable period of user inactivity. When user activity resumes, the CYW20706 immediately enters Active mode. In HIDOFF mode, the CYW20706 baseband and core are powered off by disabling power to VDDC_OUT and PAVDD. The VDDO domain remains powered up and will turn the remainder of the chip on when it detects user events. This mode minimizes chip power consumption and is intended for long periods of inactivity.

The I2S interface supports both master and slave modes. The I2S signals are: I2S clock: I2S SCK I2S Word Select: I2S WS I2S Data Out: I2S SDO I2S Data In: I2S SDI I2S SCK and I2S WS become outputs in master mode and inputs in slave mode, while I2S SDO always stays as an output. The channel word length is 16 bits and the data is justified so that the MSB of the left-channel data is aligned with the MSB of the I2S bus, per the I2S specification. 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 CYW20706 are synchronized with the falling edge of I2S_SCK and should be sampled by the receiver on the rising edge of I2S_SSCK. Document Number: 002-19479 Rev. ** Page 38 of 47 PRELIMINARY CYW20706 The clock rate in master mode is either of the following: 48 kHz x 32 bits per frame = 1.536 MHz 48 kHz x 50 bits per frame = 2.400 MHz The master clock is generated from the input reference clock using a N/M clock divider. In the slave mode, any clock rate is supported to a maximum of 3.072 MHz. Note: Timing values specified in Table 26 are relative to high and low threshold levels. Table 26. Timing for I2S Transmitters and Receivers Transmitter Lower Limit Clock Period T Receiver Upper Limit Lower Limit Upper Limit Min Max Min Max Min Max Min Max Notes Ttr - - - Tr - - - 1 Master Mode: Clock generated by transmitter or receiver HIGH tHC 0.35Ttr - - - 0.35Ttr - - - 2 LOWtLC 0.35Ttr - - - 0.35Ttr - - - 2 Slave Mode: Clock accepted by transmitter or receiver HIGH tHC - 0.35Ttr - - - 0.35Ttr - - 3 LOW tLC - 0.35Ttr - - - 0.35Ttr - - 3 Rise time tRC - - 0.15Ttr - - - - 4 Transmitter Delay tdtr - - - 0.8T - - - - 5 Hold time thtr 0 - - - - - - - 4 Receiver Setup time tsr - - - - - 0.2Tr - - 6 Hold time thr - - - - - 0 - - 6 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. Note: The time periods specified in Figure 17 and Figure 18 are defined by the transmitter speed. The receiver specifications must match transmitter performance. Document Number: 002-19479 Rev. ** Page 39 of 47 PRELIMINARY CYW20706 Figure 17.
