Renesas RA0E2
RA0E2 - 32MHz Arm Cortex-M23 Entry-Level Ultra-Low Power General-Purpose Microcontroller with 128KB ROM
The RA0E2 group is a basic, simple microcontroller (MCU) in the entry line of the RA0 series, offering excellent cost-effectiveness and ultra-low power consumption. In addition, it is a ROM/PIN extension product of the RA0E1 group, with which it is highly compatible. It delivers up to 32MHz of CPU performance using an Arm® Cortex®-M23 core with up to 128KB of embedded flash memory, 16KB SRAM, and a wide operation temperature range from -40 to 125°C. 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.
