M35B32 32 Kbit, 256-byte page, fast program EEPROM memory accessed by SPI bus interface

The M35B32 is a 32-Kbit electrically erasable programmable memory (EEPROM) accessed through the SPI bus.

The M35B32 is able to save and store up to 256 bytes within a very short time with the help of the Event sector, this feature being convenient in cases of an unexpected power loss or if an urgent data storage is required. The fast storage is performed with a very low energy budget as the Program time lasts less than 1 ms and as the supply voltage can be as low as 2.5 V associated with a low Programming current (the M35B32 is based on EEPROM cells, energy-saving technology when compared to the Flash technology).
