Overview

Description

MCF51AC256ACFUE is an 8051-based microcontroller from Freescale/NXP, part of the MCF51AC family. It integrates 256 KB of on-chip flash for program memory, on-chip RAM, and a broad set of peripherals (serial communications: UART/SPI/I2C; timers; PWM; analog peripherals: ADC/DAC; with optional USB/CAN depending on variant). It targets embedded control tasks requiring moderate performance, flexible I/O, low-power modes, and in-system programming support. The suffix ACFUE denotes the exact package and temperature-grade variant for this device; check the datasheet for precise packaging and electrical characteristics. Development tools commonly include CodeWarrior, IAR, and similar IDEs. Typical applications cover small-to-mid-size control systems, data acquisition, USB peripherals, and automotive/industrial controllers. For exact specs, consult the MCF51AC256ACFUE datasheet and user guide.

Features

Key features of MCF51AC256ACFUE (typical for this ColdFire-based MCU):
