Renesas RA0E3
32MHz Arm Cortex-M23 entry-level ultra-low power general-purpose microcontroller with 16KB flash
Renesas RA0E3 MCUs are an entry-level general purpose MCU group in the low-end RA0 series.
The RA0E3 features an Arm® Cortex®-M23 core with low power and peripherals which are optimized for BOM cost reduction and simple design. RA0E3 MCUs also support 16KB code flash, 2KB SRAM memory, a wide operating voltage range of 1.6V to 5.5V, and a wide operating temperature range of -40°C to 125°C.
Ideal for applications requiring a low pin count, RA0E3 MCUs are pin-compatible with RA0E1 (64kB ROM) and RA0E2 (64kB ROM) MCUs, offering customers design scalability across the RA0 series.
