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.
