Freescale Semiconductor Data Sheet: Advance Information Document Number: MCF51EM256 Rev.2, 4/2010 www.DataSheet4U.com MCF51EM256 MCF51EM256 Series ColdFire Microcontroller Covers: MCF51EM256 MCF51EM128 The MCF51EM256/128 series microcontrollers are a member of the ColdFire® family of reduced instruction set computing (RISC) microprocessors. This document provides an overview of these 32-bit microcontrollers, focusing on their highly integrated and diverse feature set. These microcontrollers are systems-on-chips (SoCs) that are based on the V1 ColdFire core and the following features: Operating at processor core speeds up to 50.33 MHz (peripherals operate at half of this speed) at 3.6 V to 2.5 V and 20 MHz at 2.5 V to 1.8 V Up to 256 KB of flash memory Up to 16 KB of RAM Less than 1.3 μA of typical power consumption in battery mode, with MCU supply off Ultra-low power independent RTC with calendar features, separate time base, power domain, and 32 bytes of RAM A collection of communications peripherals, including UART, IIC and SPI Integrated 16-bit SAR analog-to-digital converter Programmable delay block (PDB) Two analog comparators with selectable interrupt (PRACMP) LCD driver Three serial communications interface modules (SCI) Three serial peripheral interfaces Inter-integrated circuit (IIC) Two 8-bit and one 16-bit modulo timers (MTIM) Two-channel timer/PWM module (TPM) 80 LQFP 14 mm × 14 mm 917A-03 100 LQFP 14 mm × 14 mm 983-02 This docume...
