Built around the RTL8721 SoC from Realtek, the CMP4020 offers single-stream 24.GHz + 5 GHz 802.11n + BLE v5.0. This dual-core device features a KM4 MCU, designed by ARM and Realtek specifically for battery-powered WiFi devices, and a M0 core to manage BLE and power modes. The combination of 16 Mbit FLASH and 4.5 Mbit SRAM, combined with execute-in-place (XIP) functionality, allow room for user application code such that an external mcu is not required for most applications.
Designed for low-power requirements, SoC shutdown modes and mcu deep-sleep modes minimize current consumption to achieve maximum battery life.
