Overview
Bluetooth BR/EDR BLE Dual Mode
SOC.A highly integrated SOC for
Bluetooth data stream process and
audio player, BR8041A01 integrates a
low power MCU, RF transceiver,
Baseband, Modem, USB OTG, SARADC
and up to 24 GPIOs in a single chip.
BR8041A01 offers low cost, low power
consumption, flexible and more
powerful Bluetooth application.
BR8041A01 operates with a widely power supply range from 3.3V to 4.7V and has very low power consumption in both TX and RX modes, enabling long lifetimes in battery-operated systems while maintaining excellent RF performance. The device can enter an ultra-low power sleep mode in sniff mode.
BR8041A01 uses CMOS process with a compact 4*4mm 32-pin QFN package.
