This document provides an overview of the features and characteristics of the MCF51JM128 series. The series is a member of the ColdFire family of 32-bit reduced instruction set computing (RISC) microprocessors and offers highly integrated and diverse functionality. It 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 is a 32‑bit ColdFire microcontroller based on the V1 core, running up to 50.33 MHz and offering up to 128 KB flash, 16 KB SRAM, and a rich set of peripherals such as USB On‑The‑Go, CAN, cryptographic and random‑number generators, ADC, and multiple timers. The document details the functional units, memory options, and core capabilities of the device.
Packaging options include 80‑pin, 64‑pin, and 44‑pin LQFP packages, and the datasheet provides block diagrams, pin assignments, electrical characteristics, and revision history for designers and system integrators.
