Overview

Description

The RA2A2 group is a low-power microcontroller that combines a 48MHz Arm® Cortex®-M23 core and a rich set of peripheral functions. The RA2A2 MCU provides an optimized feature set suitable for a wide range of applications by supporting segment LCD and high-precision analog sensing functionalities while reducing power consumption, system cost, and overall footprint. Furthermore, the RA2A2's dual bank flash and security features make firmware updates easy and increase system reliability.
