MCF51JM128 ColdFire
Microcontroller
The MCF51JM128 is a member of the ColdFire
®
family of
32-bit reduced instruction set computing (RISC)
microprocessors. This document provides an overview of the
MCF51JM128 series, focusing on its highly integrated and
diverse feature set.
The MCF51JM128 series is based on the V1 ColdFire core
and operates at processor core speeds up to 50.33 MHz. As
part of Freescale’s Controller Continuum
®
, it is an ideal
upgrade for designs based on the MC9S08JM60 series of 8-bit
microcontrollers.
The MCF51JM128 features the following functional units:
