The MCF51AC256 is a member of the ColdFire family of

32-bit variable-length reduced instruction set (RISC)

microcontroller. This document provides an overview of the

MCF51AC256 series, focusing on its highly integrated and

diverse feature set.

The MCF51AC256 series is based on the V1 ColdFire core

and operates at processor core speeds up to 50.33 MHz. As

part of Freescale’s Controller Continuum , it is an ideal

upgrade for designs based on the MC9S08AC128 series of

8-bit microcontrollers.

The MCF51AC256 features the following functional units:

•

V1 ColdFire core with background debug module

Up to 256 KBytes of flash memory

Up to 32 Kbytes of static RAM (SRAM)

Up to two analog comparators (ACMP)

Analog-to-digital converter (ADC) with up to 24

channels

•

Controller-area network (CAN)

Cyclic redundancy check (CRC)

Inter-integrated circuit (IIC)

Keyboard interrupt (KBI)

Multipurpose clock generator (MCG)

Rapid general-purpose input/output (RGPIO)

Two serial communications interfaces (SCI)

Up to two serial parallel interfaces (SPI)

Two flexible timer modules (FTM)

Timer pulse-width modulator (TPM)
