EEPROM emulation driver for MCU

Posted: 17 Mar 2009     Print Version  Bookmark and Share

Keywords:MC9S08LG32  EEPROM  emulation 

The MC9S08LG32 is a member of the Freescale HCS08 family MCUs. It uses the S08 core and integrates peripherals, such as LCD, SPI, IIC, SCI, and ADC. This document is the note of the electrically erasable programmable read only memory (EEPROM) emulation driver for the MC9S08LG32 microcontroller family.

The electrically erasable programmable read only memory EEPROM can be byte, word programmed, or erased and is often used in automotive electronic control units. This flexibility for program and erase operations make it suitable for data storage of application variables that must be maintained when power is removed, and need to be updated individually during run-time. For devices without EEPROM memory, the page-erasable flash memory can be used to emulate EEPROM through EEPROM emulation software.
