Overview

Description

The RA2E1 group is the RA Family’s entry-level single-chip microcontroller based on the 48MHz Arm® Cortex®-M23 core and up to 128KB code flash and 16KB SRAM memory. The optimized processing and Renesas’ low power process technology make it the industry's most energy-efficient ultra-low power MCU. The RA2E1 group supports a wide operating voltage range of 1.6V to 5.5V and a large selection of packages such as LQFP, QFN, LGA, BGA, and WLCSP. The RA2E1 provides pin and peripheral compatibility with the RA2L1 group and is ideal for battery-operated applications and other systems requiring high performance and low-energy consumption in space-constrained applications.
