Freescale Semiconductor Document Number: MCF51AC256 Rev.7, 9/2011 Data Sheet: Technical Data MCF51AC256 MCF51AC256 Series 80 LQFP 64 LQFP ColdFire Microcontroller 14 mm 14 mm 10 mm 10 mm Covers:MCF51AC256A 44 LQFP 64 QFP MCF51AC256B 10 mm 10 mm 14 mm 14 mm MCF51AC128A MCF51AC128C Two serial communications interfaces (SCI) The MCF51AC256 series are members of the ColdFire family of 32-bit variable-length reduced Up to two serial peripheral interfaces (SPI) instruction set (RISC) microcontroller. This Two flexible timer modules (FTM) document provides an overview of the Timer pulse-width modulator (TPM) MCF51AC256 series, focusing on its highly integrated and diverse feature set. The MCF51AC256 series are based on the V1 ColdFire core and operates at processor core speeds up to 50.33 MHz. As part of Freescales 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 KB of flash memory Up to 32 KB 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) This document contains information on a product under development.
