RA2E2 Arm® Cortex®-M23 MCU

The RA2E2 group is the RA family’s entry line single-chip microcontroller based on the 48 MHz Arm Cortex-M23 core with Renesas' innovative on-chip peripheral functions. The RA2E2 group offers ultra-low power operation and high-speed serial communication with small 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 controls, and any battery-operated application that requires developers to cut power consumption, cost, and space.
