EEPROM Emulation with ST10F2xx

STMicroelectronics 

AN2061

1 INTRODUCTION

Substituting external EEPROM with emulated EEPROM from the embedded-Flash of the Mi-

crocontroller is a complex development. This application note assumes that readers are al-

ready familiar with the techniques used to secure the content of evolutive information in

external EEPROM of embedded applications.

This application note is organized in 3 parts:

– description of the differences between external EEPROMs and embedded-Flash,

– general description of EEPROM emulation concept,

– introduction to embedded application aspects.

Although this application note is focused and applicable to ST10F269, ST10F280, ST10F276

(and its derivatives: ST10F275, ST10F273, ST10F272, ST10F271), ST10F252 and

ST10F296, most of its content is not dependent on the microcontroller.
