EEPROM emulation with Qorivva MCUs
Electrically Erasable and Programmable Read Only Memory (EEPROM) is typically used in applications where runtime-modifiable data needs to be retained after the power has been removed. Although the Qorivva MPC55xx, MPC56xx, and MPC57xx family of microcontrollers do not include EEPROM, the functionality of this memory type can be emulated with the flash memory that is available. This document describes the basic principles behind using Qorivva flash memory for EEPROM emulation, and provides some insight on the functionality of Freescale EEPROM emulation drivers.
