The RA2E3 group is an entry-line, single-chip microcontroller in the RA family based on the 48MHz Arm® Cortex®-M23 core with up to 64KB code flash and 16KB SRAM memory. RA2E3 MCUs provide an optimized feature set for cost-sensitive applications by supporting pin-to-pin and peripheral compatibility with RA2E1 MCUs. Ultra-low power consumption contributes to energy-efficient system design, required for IoT applications and battery-operated systems to achieve longer battery life.
