MCF51EM256 Series

ColdFire Microcontroller

Covers: MCF51EM256

MCF51EM128

The MCF51EM256/128 series microcontrollers are

a member of the ColdFire family of reduced

•

Three serial communications interface

modules (SCI)

instruction set computing (RISC) microprocessors.

•

Three serial peripheral interfaces

Inter-integrated circuit (IIC)

Two 8-bit and one 16-bit modulo timers

(MTIM)

This document provides an overview of these

32-bit microcontrollers, focusing on their highly

integrated and diverse feature set.

•

Two-channel timer/PWM module (TPM)

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

3.6 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
