5 DATA EEPROM
5.1 INTRODUCTION
The Electrically Erasable Programmable Read
Only Memory can be used as a non volatile back-
up for storing data. Using the EEPROM requires a
basic access protocol described in this chapter.
5.2 MAIN FEATURES

s
EEPROM mono-voltage (charge pump)
s
Chained erase and programming cycles
s
Internal control of the global programming cycle
duration
s
WAIT mode management
