UM0401 RTL872xD Datasheet
■RTL872xD is a highly integrated single-chip low power dual bands (2.4GHz and 5GHz) Wireless LAN (WLAN) and Bluetooth Low Energy (v5.0) communication controller. It consists of a high-performance MCU (ARM v8m, Cortex-M4F instruction compatible) named KM4, a low power MCU(v8m, Cortex-M0 instruction compatible) named KM0, WLAN (802.11a/b/g/n) MAC, an 1T1R capable WLAN baseband, RF, Bluetooth and peripherals.
■High speed connectivity interfaces, SDIO and USB are provided.There are also audio codec, Key-Scan and touch keys integrated into this IC. Besides, flexible design configures GPIO to different functions according to applications.
■RTL872xD also integrates memories (ROM/SRAM/PSRAM) for IoT (Internet of Things) Wi-Fi protocol functions and applications. The user-friendly development kits (SDK and HDK) are supported to customers for developing IoT applications.
■The KM4 MCU is a 32-bit core that offers system enhancements such as low power consumption, enhanced debug features, floating point computation, DSP instructions and a high level of support block integration. The KM4 MCU incorporates a 3-stage pipeline. The KM0 coprocessor is an energy-efficient and easy-to-use 32-bit core which is code-and tool-compatible with the KM4 core.
■The KM0 coprocessor offers up to 20MHz performance with a simple instruction set and reduced code size.
