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
– 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
from 220000h to 2203FFh.

tion, see application note AN1152)
