AB1120 is a single-chip IC for HID applications, which supports Bluetooth system version
3.0 features including AFH function. It supports sniff sub-rating for longer battery life &
faster re-connect. Bluetooth 3.0 simple-pairing mechanism is also implemented. AB1120’s
scatternet can join up to 3 piconets. It complies with RF transceiver, baseband processor,
PMU, switching regulator, Boost regulator and Li-ion battery charger. Several Serial
Communication Interfaces including USB, UART, I2C and SPI are supported.
