Nuvoton ML51 Low-Power 8051 MCU

Nuvoton NuMicro® M031/M032 series is 32-bit microcontrollers based on Arm® Cortex®-M0 core with 32-bit hardware multiplier/divider. It features 1.8V ~ 3.6V operating voltage, 5V I/O tolerant, running up to 48/72 MHz within -40~105°C.
M031 series provides a solution for the applications that need 1.8V low-voltage interface connection with enhanced fast 2 MSPS conversion rate 12-bit ADC, comparators and up-to 24-ch 96/144 MHz PWM control, providing a fast and precise data conversion for the voltage, current, and sensor data, then fast response control to the external device.

With low power technology, Nuvoton ML51 series is based on 1T 8051 core microcontroller to support power down current below 1 μA, power consumption is 80 μA/MHz in normal run mode. It provides operating frequency up to 24MHz, operating voltage from 1.8V to 5.5V and operating temperature -40°C ~ 105°C.
