Overview
Description
M251ZC2AE is a member of Nuvoton’s M251 family of 8‑bit, 8051‑compatible microcontrollers. It targets general-purpose embedded control tasks in consumer and industrial applications.
- Core and memory: 8-bit MCS-51 core with on-chip flash and RAM (sizes vary by specific part).
- Peripherals: multiple serial interfaces (UARTs), SPI, I2C, timers, PWM outputs, and analog peripherals (such as ADC); broader I/O options are supported depending on the variant. Some variants may include USB or touch features.
- Power and clock: supports multiple clock sources and low-power modes to suit energy-sensitive designs.
- Development: supported by Nuvoton’s NuMicro ecosystem, with libraries, SDKs, and example code; consult the datasheet for exact pinout, electrical specs, and timing.
Note: M251ZC2AE denotes a specific package/option code; exact memory size, peripherals, and packaging are variant-specific—check the official datasheet for precise details.
