BlueCore® CSR8311 QFN Automotive Features ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ Bluetooth® v4.1 Specification Bluetooth Smart Ready CSR8311A12 Production Information Issue 1 General Description Applications CSR8311 QFN is a product from CSR's Connectivity Centre. It is a single-chip radio and baseband IC for Bluetooth 2.4GHz systems including EDR to 3Mbps and Bluetooth Smart. Dedicated signal and baseband processing is included for full Bluetooth operation. When used with CSR's Synergy host software suite, CSR8311 QFN provides a system fully qualified to the Bluetooth v4.1 specification for data and voice communications. Automotive USB Bluetooth dongles CSR designed CSR8311 QFN to reduce PCB area and the number of external components, including no requirement for an external balun. This ensures that production costs are minimised. The device incorporates auto-calibration and BIST routines to simplify development, type approval and production test. ■ ■ RAM USB ROM BT RF 2.4GHz Radio MMU MCU Kalimba DSP Core UART I/O PIO PCM/SPI/I 2S XTAL Production Information © Cambridge Silicon Radio Limited 2015 Confidential Information - This Material is Subject to CSR's Non-Disclosure Agreement Page 1 of 3 CS-324217-TOP1 www.csr.com CSR8311 QFN Automotive A12 Technical Overview ■ ■ ■ ■ ■ Fully qualified Bluetooth® v4.1 system Full-speed Bluetooth operation with full piconet and scatternet support Class 1 Bluetooth power level supported High-sensitivity Bluetooth receiver Wideband speech On-chip SBC encoding On-chip balun Low-power selectable 1.2 to 3.6V I/O No external regulators required for USB supply operation Full-speed USB 2.0 interface Integrated I/O and core regulators High-speed UART port (up to 4Mbps) 2 x PCM/I²S digital audio interfaces Support for IEEE 802 ®.11 coexistence Optimised for use on low-cost PCBs 40-lead 6 x 6 x 0.9mm, 0.5mm pitch QFN Green (RoHS compliant and no antimony or halogenated flame retardants) Device Details Bluetooth Stack CSR's Bluetooth Protocol Stack runs up to HCI on the on-chip MCU Synthesiser ■ Fully integrated synthesiser requires no external VCO varactor diode, resonator or loop filter ■ Compatible with external clock 16MHz to 40MHz and crystal oscillator 16MHz to 32MHz Physical Interfaces ■ Full-speed (12Mbps) USB 2.0 interface ■ Synchronous serial interface up to 4Mbps for system debugging ■ UART interface with programmable baud rate up to 4Mbps ■ BCSP, H4, H4DS and H5 support ■ 2 x PCM interface/I²S interface Auxiliary Features ■ Power management includes digital shutdown and wake up commands with an integrated low power oscillator ■ Auto Baud Rate setting, depending on host interface ■ Integrated linear regulators: ■ USB: USB bus supply to 3.3V ■ High-voltage: 2.3V to 4.8V input to 1.85V ■ Low-voltage: VDD_DIG, VDD_ANA and VDD_AUX regulators ■ Arbitrary sequencing of power supplies is permitted Package ■ 40-lead 6 x 6 x 0.9mm, 0.5mm pitch QFN ■ Low-cost PCB with no laser via needed ■ Production Information © Cambridge Silicon Radio Limited 2015 Confidential Information - This Material is Subject to CSR's Non-Disclosure Agreement Page 2 of 3 CS-324217-TOP1 www.csr.com CSR8311 QFN Automotive A12 Technical Overview Bluetooth Smart ■ Dual-mode Bluetooth Smart radio ■ Support for Bluetooth basic rate/EDR and Bluetooth Smart connections ■ 3 Bluetooth Smart connections at the same time as basic rate A2DP Bluetooth Radio ■ Integrated balun (50Ω impedance in TX and RX modes) ■ No external trimming is required in production ■ Bluetooth v4.1 specification compliant Bluetooth Transmitter ■ 9.5dBm (typical) RF transmit power (basic rate) with level control from on-chip 6-bit DAC ■ Class 1, Class 2 and Class 3 support without need for external power amplifier or TX/RX switch ■ DQPSK and 8DPSK Bluetooth Receiver ■ -92.5dBm (typical) π/4 DQPSK sensitivity ■ Integrated channel filters ■ Digital demodulator for improved sensitivity and cochannel rejection ■ Real time digitised RSSI available on HCI interface ■ Fast AGC for enhanced dynamic range ■ Channel classification for AFH ■ 2Mbps and 3Mbps EDR support Baseband and Software ■ Internal RAM enables full-speed data transfer, mixed voice and data, and full piconet operation, including all medium rate packet types ■ Logic for forward error correction, header error control, access code correlation, CRC, demodulation, encryption bit stream generation, whitening and transmit pulse shaping.
