ROHM Semiconductor 125°C I2C BUS EEPROMs for 2-Wire Automotive
ROHM Semiconductor 125°C I2C BUS EEPROMs for 2-Wire Automotive are AEC-Q100 qualified. The ROHM I2C BUS EEPROMs feature two ports of Serial Clock (SCL) and Serial Data (SDA) that all controls are available through. The EEPROMs operate from a wide limit of 1.7V to 5.5V, with a possible 1MHz operation.
The I2C BUS EEPROMs offer a low current consumption, a page write mode of 32Byte/64Byte, and a bit format of 8K x 8bit/16K x 8bit. The 125°C I2C BUS EEPROMs are available in SOP8, SOP-J8, TSSOP-B8, MSOP8, and VSON008X2030 packages with an ambient operating temperature of -40°C to +125°C.
