Appendix Acronyms and Abbreviations 32 Document History 33 Page 3 of 35 CYW20732A0 Functional Description 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 data routing 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 TX/RX data reliability and security 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 dewhitening. • Transmit Functions data framing, FEC generation, HEC generation, CRC generation, link key generation, data encryption, and data whitening. Frequency Hopping Generator The frequency hopping sequence generator selects the correct hopping channel number depending on the link controller state, Bluetooth clock, and device address. E0 Encryption The encryption key and the encryption engine are implemented using dedicated hardware to reduce software complexity and provide minimal processor intervention. 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 software commands, and other controllers that are activated or configured by the Command Controller to perform the link control tasks. Each task performs a different Bluetooth link controller state. STANDBY and CONNECTION are the two major states. In addition, there are five substates page, page scan, inquiry, and inquiry scan. Adaptive Frequency Hopping The CYW20732 gathers link quality statistics on a channel-by-channel basis to facilitate channel assessment and channel map selection. The link quality is determined by using both RF and baseband signal processing to provide a more accurate frequency hop map. Bluetooth Low Energy Profiles The CYW20732 supports Bluetooth low-energy, including the following profiles that are supported1 in ROM • Battery status • Blood pressure monitor • Find me • Heart rate monitor • Proximity • Thermometer • Weight scale • Time The following additional profiles can be supported1 from RAM • Blood glucose monitor • Temperature alarm • Location • Custom profile Full qualification and use of these profiles may require firmware updates from Cypress. Some of these profiles are under development/approval at the Bluetooth SIG and conformity with the final approved version is pending. Contact your supplier for updates and the latest list of profiles. Page 4 of 35 CYW20732A0 Test Mode Support The CYW20732 fully supports Bluetooth Test mode, as described in the Bluetooth low energy specification. Infrared Modulator The CYW20732 includes hardware support for infrared TX. The hardware can transmit both modulated and un-modulated 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 and 32,767 µsec. The CYW20732 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 under run see Figure 2 on page Figure Infrared TX Infrared Learning The CYW20732 includes hardware support for infrared learning. The hardware can detect both modulated and unmodulated signals. For modulated signals, the CYW20732 can detect carrier frequencies between 10 500 kHz and the duration that the signal is present or absent. The CYW20732 firmware driver supports further analysis and compression of learned signal. The learned signal can then be played back through the CYW20732 IR TX subsystem see Figure Figure Infrared RX Page 5 of 35 CYW20732A0 ADC Port The CYW20732 contains a 16-bit ADC effective number of bits is Additionally: • There are nine analog input channels in the 32-pin package • The following GPIOs can be used as ADC inputs P0 P1 P8/P33 select only one P11 P12 P13/P28 select only one P14/P38 select only one P15 P32 • The conversion time is 10 us. • There is a built-in reference with supply- or bandgap-based reference modes. • The maximum conversion rate is 187 kHz. • There is a rail-to-rail input swing. 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. The ADC input range is selectable by firmware control: • When an input range of is used, the input impedance is 3 • When an input range of is used, the input impedance is • When an input range of is used, the input impedance is 680 ADC modes are defined in Table Table ADC Modes Mode ENOB Typical Maximum Sampling Rate kHz 187 Latencya us 171 85 21 11 5 a.Settling time after switching channels. Serial Peripheral Interface The CYW20732 has two independent SPI interfaces. One is a master-only interface and the other can be either a master or a slave. Each interface has a 16-byte transmit buffer and a 16-byte receive buffer. To support more flexibility for user applications, the CYW20732 has optional I/O ports that can be configured individually and separately for each functional pin as shown in Table 3, Table 4, and Table The CYW20732 acts as a SPI master device that supports 1.8V or 3.3V SPI slaves. The CYW20732 can also act as an SPI slave device that supports a 1.8V or 3.3V SPI master.
