3 SINGLE VOLTAGE FLASH & 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-

ST92F120 - SINGLE VOLTAGE FLASH & EEPROM
ond part contains the two dedicated Flash sectors
used for EEPROM Hardware Emulation.
The write operations of the two parts are managed
by an embedded Program/Erase Controller, that
uses a dedicated ROM. Through a dedicated RAM
buffer the Flash and the EEPROM can be written
in blocks of 16 bytes.
