ST92F124/F150/F250 - SINGLE VOLTAGE FLASH & E3 TM (EMULATED EEPROM)

3 SINGLE VOLTAGE FLASH & E3 TM (EMULATED EEPROM)

3.1 INTRODUCTION

The Flash circuitry contains one array divided in

two main parts that can each be read independ-

ently. The first part contains the main Flash array

for code storage, a reserved array (TestFlash) for

system routines and a 128-byte area available as

one time programmable memory (OTP). The sec-

ond part contains the two dedicated Flash sectors

used for EEPROM Hardware Emulation.

The write operations of the two parts are managed

embedded

Program/Erase

Controller.

Through a dedicated RAM buffer the Flash and the

E3 TM

can be written in blocks of 16 bytes.
