概述

Description

NUC442VI8AE is a 32‑bit microcontroller from Nuvoton’s NuMicro NUC4xx family. It uses an ARM Cortex‑M4F core (with FPU) and integrates flash and RAM on the chip. It targets embedded control and IO‑rich applications and offers a broad peripheral set, including USB 2.0 full‑speed, multiple UARTs, SPI, I2C, PWM and general‑purpose timers, and an ADC. It supports low‑power modes and comes in various package options to fit space and cost requirements. The VI8AE suffix denotes a specific package/temperature variant of the NUC442 family.
For exact specs—flash/RAM size, max CPU frequency, peripheral counts, electrical characteristics, and development tools—consult the official datasheet and user manual on Nuvoton’s website.
