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.
