The MCF51AG128 is a member of the ColdFire family of

– Low-voltage detection with reset or interrupt

– Separate low voltage warning with selectable trip points

– Illegal opcode and illegal address detection with reset

– Flash block protection for each array to prevent

accidental write/erasure

32-bit variable-length reduced instruction set (RISC)

microcontroller. This document provides an overview of the

MCF51AG128 series MCUs, focusing on its highly

integrated and diverse feature set.

– Hardware CRC module to support fast cyclic

redundancy checks

• Debug Support

The MCF51AG128 derivative are low-cost, low-power, and

high-performance 32-bit ColdFire V1 microcontroller units

(MCUs) designed for industrial and appliance applications. It

is an ideal upgrade for designs based on the MC9S08AC128

series of 8-bit microcontrollers.

– Single-wire back ground debug interface

– Real-time debug support, with six hardware breakpoints

(4 PC, 1 address pair and 1 data) that can be configured

into a 1- or 2-level trigger

– On-chip trace buffer provides programmable start/stop

recording conditions

The MCF51AG128 features the following functional units:

• 32-bit Version 1 ColdFire central processor unit (CPU)

– Up to 50.33 MHz ColdFire CPU from 2.7 V to 5.5 V

– Provide 0.94 Dhrystone 2.1 DMIPS per MHz

performance when running from internal RAM (0.76

DMIPS per MHz when running from flash)

– Implements Coldfire Instruction Set Revision C

(ISA_C)

– Support for real-time program (and optional partial data)

trace using the debug visibility bus

• DMA Controller

– Four independently programmable DMA channels

provide the means to directly transfer data between

system memory and I/O peripherals

– DMA enabled peripherals include IIC, SCI, SPI, FTM,

HSCMP, ADC, RTC, and eGPIO, and the DMA request

from these peripherals can be configured as DMA

source or as an iEvent input

• On-chip memory

– Up to 128 KB flash memory read/program/erase over

full operating voltage and temperature

– Up to 16 KB random access memory (RAM)

– Security circuitry to prevent unauthorized access to

RAM and flash contents

• CF1_INTC

• Power-Saving Modes

– Support of 44 peripheral I/O interrupt requests and seven

software (one per level) interrupt requests

– Fixed association between interrupt request source, level

and priority, up to two requests can be remapped to the

highest maskable level and priority

– Unique vector number for each interrupt source

– Support for service routine interrupt acknowledge

(software IACK) read cycles for improved system

performance

– Three ultra-low power stop modes and reduced power

wait mode

– Peripheral clock enable register can disable clocks to

unused modules, thereby reducing currents

• System Protection

– Advanced independent clocked watchdog (WDOG)

with features like, robust refresh mechanism, windowed

mode, high granulation timeout, fast test of timeout, and

always forces a reset

– Additional external watchdog monitor (EWM) to help

reset external circuits

– Ability to mask any individual or all interrupt sources

Freescale reserves the right to change the detail specifications as may be required to permit

improvements in the design of its products.
