Renesas RA0E1

The RA0E1 group is the product which aims to Low-end Arm® MCU market. This product implements the Arm® Cortex®-M23 core with low power and peripherals which are optimized for BOM cost reduction and simple design for the low-end MCU market. The RA0E1 group supports up to 64-KB code flash, 12-KB SRAM memory and a wide operating voltage range of 1.6V to 5.5V.

The RA0E1 package lineup starts with 16-pin up to 32-pin and Flash memory size starting from 32KB up to 64KB, including some of small package option line QFN (3mm x 3mm). Also, provides pin and peripheral compatibility with RA2E1, the most popular Arm MCU in the Renesas portfolio. This wide range of scalability manifests itself in optimum flexibility for the MCU SW and HW designers when needing extra I/O lines or additional peripheral functions. Designers only need to migrate to the next pin count size to gain extra I/O lines and functionality.   

RA0E1 is the first MCU group in the brand new RA0 series and stands out for its lowest power consumption, optimized peripherals, and cost-effectiveness, making it well-suited for cost-sensitive applications.
