Automotive Series Serial EEPROMs

EEPROMs

A serial EEPROM(Electrically Erasable Programmable Read Only Memory) is non-volatile memory that can be overwritten electrically, in units of bytes, and is most suitable for data storage use.

ROHM's high reliability serial EEPROMs are among the top of their class.
