Recently, Renesas Electronics released a low-cost 32-bit microcontroller based on the Cortex-M23 core, with a clock frequency of up to 32M in the RA0 series low-power MCU:
The new RA0 series of the Renesas RA MCU family introduces the RA0E1 product group, which is an entry-level easy-to-use MCU with excellent cost-effectiveness and ultra-low power consumption. It integrates the Arm® Cortex®-M23 core, with up to 64KB of flash memory, and a wide operating voltage range of 1.6V to 5.5V, providing CPU performance of up to 32MHz. The RA0 series is very suitable for cost-sensitive applications, such as low-power, low-cost consumer electronics, small appliance system control, industrial system control, and building automation.
