The devices cascadable feature allows up to four devices to share a common 2-wire bus. The device is optimized for use in many industrial and commercial applications where low power and low voltage operation are essential. The devices are available in space-saving 8-lead JEDEC SOIC, 8-lead EIAJ SOIC, 8-lead TSSOP, and 8-ball WLCSP. In addition, the entire family is available in 1.7V (1.7V to 5.5V) and 2.5V (2.5V to 5.5V) versions. Atmel-8812F-SEEPROM-AT24CM01-Datasheet 0120151.
