BR93A46RF-WM
1KBit, MicroWire BUS, Serial EEPROM for Automotive (105℃ Operation)

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. The entire series are both lead-free and RoHS-compliant.
