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.
