BC870FNA is a Bluetooth Class2 (max 4dBm) module. It is based on the most advanced
CSR BC8670
chip set and the latest ADK standard. The new RISC MCU
core and 80MIPS Kalimba DSP Co-Processor enable not the existing Bluetooth multi-media function
such as stereo audio (A2DP audio) communications but also extended features for future. The highly
integrated hardware includes high quality stereo DAC, high current (200/500mA) battery charger, thus
saving costs of external components. The host Interfaces include USB, I2S, SPI and UART, that are
programmable for data communication, module control or firmware upgrade.
The powerful and flexible design allows the module to support HSP/HFP/A2DP/AVRCP SPP, PBAP
and most Bluetooth Classic profiles, at the same handling LE profiles for applications like battery
reporting, remote control and HID. Furthermore, the APTX, AAC, MP3 HIFI audio streaming are also
supported.
The complete module design relieves host system developers from handling complex Bluetooth
operations and compatibility issues. Furthermore, BC870FPA has built-in PCB antenna. It eliminates
the need of antenna design, matching and testing in host system development, also reduces the RF
test requirements of end-product production.
