8/16-BIT SINGLE VOLTAGE FLASH MCU FAMILY WITH RAM, E³ ™ (EMULATED EEPROM), CAN 2.0B AND J1850 BLPD

STMicroelectronics 

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

3.2 FUNCTIONAL DESCRIPTION

3.2.1 Structure

The memory is composed of three parts:

– a sector wih the system routines (TestFlash) and

the user OTP area

– 4 main sectors for code

– an emulated EEPROM

124 bytes are available to the user as an OTP ar-

ea. The user can program these bytes, but cannot

erase them.

3.2.2 EEPROM Emulation

A hardware EEPROM emulation is implemented

using special flash sectors to emulate an EEP-

ROM memory. This E3 TM is directly addressed

from 220000h to 2203FFh.

(For more details on hardware EEPROM emula-

tion, see application note AN1152)
