Description

The RA2E2 Group is RA Family’s entry-line single-chip microcontroller based on the 48-MHz Arm® Cortex®-M23 core with Renesas' innovative on-chip peripheral functions. RA2E2 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 package, satisfying the needs of cost-sensitive and space-constrained applications. These RA2E2 Group 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.
