1. General Description
1.1. Overview
The RTL8762CK (hereafter referred to as the RTL8762C except where differences exist) is an
ultra-low-power system on-chip solution for Bluetooth 5.0 low energy applications that combines
the excellent performance of a leading RF transceiver with a low-power ARM Cortex-M4F and
rich powerful supporting features and peripherals.
The RTL8762C supports an analog MIC interface that integrates a sigma-delta ADC,
programmable gain amplifier, 5-Band equalizer and microphone bias circuit for voice command
application. The RTL8762C embeds IR transceiver, hardware key-scan, and Quad-decoder on a
single IC, and is provided in a QFN package.
1.2. MCU Platform
The embedded ARM Cortex-M4F 32-bit CPU features a 16-bit instruction set with 32-bit
extensions (Thumb-2® technology) t hat delive rs high-dens ity code w ith a small memory footpr int.
By using a single-cycle 32-bit multiplier, a 3-stage pipeline, and a Nested Vector Interrupt
Controller (NVIC), the ARMCortex-M4F makes program execution simple and highly efficient.
Serial Wire Debug (SWD) interface provided as part of the Debug Access Port (DAP), in
conjunction with the Basic Branch Buffer (BBB). This offers a flexible and powerful mechanism
for non-intrusive program code debugging. Developers can easily add breakpoints in the code and
perform single-step debugging.
The RTL8762C memory architecture includes ROM, 160kByte RAM and 8MByte Flash Address
Space.
The 160kByte RAM consists of RAM1 (112kByte Data RAM), RAM2 (8kByte Cache Shared
RAM), RAM3 (8kByte Cache Shared RAM), an d RAM4 (32kByte Buffer RAM). All the RAM
regions can be used to execute code and hold data.
Flash Address Space is a virtual space which is mapped to external Flash to extend the code space
in XIP (eXecute In Place) mode.
