32-bit Microcontrollers

MCF51EM

Smart metering made easy with V1 ColdFire

Target Applications

• Smart metering

• Sensor collection

• Phase measurement units

• Industrial energy measurement

• 1- and 3- phase electricity meters

Overview

MCF51EM 32-bit MCU is a highly-integrated

single-chip device with high-performance

peripherals.

Unique features of the MCF51EM family

include 4 x 16-bit SAR ADC with PDB for

precision sequencing of four simultaneous

conversions and four conversions with small

delay required for CT compensation, up to 288

segment LCD driver and two blocks of 128

KB flash (256 KB total), independent RTC with

tamper detection providing more than 15 years

from CR2032 coin cell and more than 30 years

when powered by MCU, 32-bit MAC and AMR

SPI for 5V AMR interface. These features are

ideal for smart metering applications.
