Using the ColdFire Flash Module with the MCF521x ColdFire Microcontroller

Using the ColdFire Flash Module with the MCF521x ColdFire Microcontroller

This document is a quick reference to get the FLASH module configured for the MCF521x microcontroller. It includes basic functional description and configuration options to give the user a better understanding of how the flash module works. This application note provides an example that demonstrates how to configure the flash module for the MCF521x microcontroller. The examples mentioned may be modified to suit the specific needs for any application.

The ColdFire FLASH module (CFM) is a nonvolatile memory (NVM) module for integration with a CPU. The CFM provides 256 Kbytes of 32-bit flash memory serving as electrically erasable and programmable, nonvolatile memory. The flash memory is ideal for programming and data storage for single-chip applications, allowing field reprogramming without requiring external programming voltage sources.
