Serial EEPROM
ROHM's serial EEPROMs are available in a range of interfaces, package types, and storage capacities.
BR24G-5A (I2C), BR24H-5AC (Automotive, I2C), BR25H-5AC (Automotive, SPI) have high speed writing feature at 3.5ms which helps to improve production efficiency. The endurance of write cycle has achieved 4 million times, which makes it possible to design long-life sets. They are also suitable for keyless entry and battery-powered equipment by low voltage operation.
