3 SINGLE VOLTAGE FLASH & E
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-

(EMULATED 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.
Through a dedicated RAM buffer the Flash and the
