RA2E1

The RA2E1 group is RA Family’s entry line single-chip microcontroller based on the 48-MHz Arm^® Cortex^®-M23 core and up to 128-KB code flash and 16-KB SRAM memory. The optimized processing and Renesas’s low power process technology make it the industry's most energy-efficient Ultra-Low Power. 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 RA2L1 group, is ideal for battery-operated applications and other systems requiring high performance and low-energy consumption in space constrained applications.
