Description

The RA0E1 group is a basic, simple MCU in the entry line of the RA0 series, offering excellent cost effectiveness and ultra-low power consumption. It delivers up to 32MHz of CPU performance using an Arm® Cortex®-M23 core with up to 64KB of embedded flash memory and a wide supply voltage range from 1.6V to 5.5V. The RA0 series is ideal for cost-sensitive applications such as low power and lower cost for consumer electronics, system control for small appliances, industrial system control, and building automation.
