NuMicro® M251/M252 Microcontrollers

Nuvoton NuMicro® M251/M252 Microcontrollers are a low-power platform based on the Arm® Cortex®-M23 core for Armv8-M architecture. The MCUs operate up to 48MHz with 32Kbytes to 256Kbytes embedded Flash memory, 8Kbytes to 32Kbytes embedded SRAM, and 4Kbytes Flash loader memory (LDROM) for InSystem Programming (ISP). The 32-bit microcontrollers provide a wide supply voltage from 1.75V to 5.5V and an operating temperature range from -40°C to +105°C.
