Renesas RA2E2 Series MCUs

48MHz Arm® Cortex®-M23 Ultra-Low Power General Purpose Microcontroller

The Renesas RA2E2 Group of MCUs, the RA Family’s entry line single-chip microcontroller, is based on the 48-MHz Arm® Cortex®-M23 core.

Coupled with Renesas' innovative on-chip peripheral functions, the RA2E2 MCU Group offers ultra-low power operation and high speed serial communication with the smallest package options of 20-pin and 24-pin QFN and 16-pin wafer-level CSP. This satisfies the needs of cost-sensitive and space-constrained applications.

The Renesas RA2E2 Group of microcontrollers enable extremely cost-effective designs for IoT sensor nodes, portable devices, industrial control, and any battery-operated application that requires developers to cut power consumption, cost and space.
