It is a single-chip radio and baseband IC for Bluetooth 2.4GHz systems including EDR to 3Mbits/s and Bluetooth low energy. CSR8811 WLCSP's dual-mode radio enables it to connect to the billions of Bluetooth products already on the market, as well as a new generation of Bluetooth low energy devices. Consumer electronics devices, for example: ■ Portable navigation devices ■ Point of sale terminals ■ Personal media players CSR designed CSR8811 WLCSP to reduce PCB area and the number of external components: ■ The high-power Class 1 Bluetooth transmitter removes the requirement for external amplification. ■ The balun is integrated, which results in a singleended 50Ω port that does not require additional matching components. ■ Integrated LDOs, with minimum decoupling components required, allow the chip to be operated directly from a battery or regulated supply. ■ No requirement for external inductors. This ensures that production costs are minimised. The device incorporates auto-calibration and BIST routines to simplify development, type approval and production test. To improve the performance of both Bluetooth and IEEE 802.11b/g/n co-located systems a wide range of coexistence features are supported. When used with CSR Synergy® Software and a CSR UniFi ® wireless chip, CSR8811 WLCSP provides a system fully qualifiable to the Bluetooth v4.1 for faster file transfer. This family of Bluetooth products includes: ■ CSR8311 A12 for automotive applications Products requiring a standalone Bluetooth low energy radio should use products of the CSR101x™ family.
