The RA0L1 group is the first product with capacitive touch functionality in the RA0 MCU series. This product implements an Arm® Cortex®-M23 core with low power and peripherals that are optimized for BOM cost reduction and simple design for the low-end MCU market. The RA0L1 group supports up to 64KB code flash, 16KB 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. 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.
