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
â–  Up to 32 Bytes programmed in the same cycle
â–  EEPROM mono-voltage (charge pump)
â–  Chained erase and programming cycles
â–  Internal control of the global programming cycle
duration
â–  WAIT mode management
â–  Readout protection
