6222N-IMA IoT Module

 Introduction

6222N-IMA is a highly integrated IoT module with low power 802.11a/b/g/n Wireless LAN (WLAN) and Bluetooth Low Energy communication controller. It combines a high-performance KM4 MCU, a low power KM0 MCU, WLAN (802.11 a/b/g/n) MAC, a 1T1R capable WLAN baseband, RF, Bluetooth. 

High speed connectivity interfaces, SDIO and USB are provided. Also audio codec, key-scan and touch keys integrated. Flexible design configures GPIO to different functions. 

6222N-IMA integrates internal memories for complete Wi-Fi protocol functions.
