High Reliability Series Serial EEPROMs

A serial EEPROM (Electrically Erasable Programmable Read Only Memory) is non-volatile memory that can be overwritten electrically, in units of bytes. It is used in computers and other electronic devices to store small amounts of data. ROHM offers top-class high reliability serial EEPROMs.

I2C BUS BR24□□□□Family Compatible with I2C BUS, utilizing 2-wire communication: SCL (Serial Clock), SDA (Serial Data) Devices other than EEPROMs can connect to the same port, minimizing the number of ports required. Single power source: 1.7V to 5.5V (BR24S□□□series); compatible with low voltage Fast Mode operation	SPI BUS BR25□□□□Family High 5MHz (max.) clock frequency Wait function via Hold terminal Part of or the entire memory array can be set to prevent write operations (ROM)
