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. They command a large market share and are available in a range of capacities, bus interfaces (Microwire, I2C, SPI), operating voltages (1.8V to 5.5V, 2.5V to 5.5V) and package types, making them ideal for battery powered devices. In addition, the entire series utilizes unique double cell construction, significantly improving reliability, and are both lead-free and RoHS-compliant.
ROHM's serial EEPROMs are top shelf products featuring high reliability.
Unique double-cell construction and double reset functionality prevents data write errors, safeguarding your most important data. The highest quality is ensured through an integrated production process, from wafer to assembly.
