ST7FLITE0 QUICK REFERENCE NOTE

The ST7FLITE09 contains an Electrically Erasable Programmable Read-Only Memory which

can be used as a non volatile back-up for storing data. It allows up to 300K Write/Erase cycles

at 25°C.

Main Features

- Up to 32 Bytes programmed in the same cycle

- mono-voltage EEPROM (charge pump)

- Chained erase and programming cycles

- Internal control of the global programming cycle duration

- WAIT mode management

- Read-out protection against piracy

read-out piracy. This is managed by the option bit “Read-out protection”. Removing this option

by erasing the option byte will cause the whole memory to be erased first.

Flash program memory can also be protected against re-write operation by option bit “Flash

Write protection”. When this option is selected, the program memory can never be erased or

programmed again.
