RTL8763B Series

Bluetooth 5

Datasheet Preliminary

1. General Description

The RT8763B series are single-chip Bluetooth ROM audio solutions for mono (RTL8763BM) and stereo
(RTL8763BF/BFR, RTL8763BS, RTL8763BA) applications. The RT8763B is composed of an ARM
core and an ultra-low power DSP core with high efficiency computing power, high performance audio
codec, power management unit, ADC, ultra-low current RF transceiver, and smart I/O distribution
controller.

The parameter configuration tools, the EVB kits, and the MP kits, including controller hardware and
software, provide a simple and flexible procedure for customers to quickly design and proceed to mass
production with Realtek’s new generation of audio solutions. These complete total solutions provide a
fast and highly reliable development path with a very competitive R-BOM.
