Description
The Atmel® AT24C512C provides 524,288 bits of Serial Electrically Erasable and Programmable Read-Only Memory (EEPROM) organized as 65,536 words of 8 bits each. The cascadable feature of the device allows up to eight 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, 8-pad UDFN, 8-ball WLCSP, and 8-ball VFBGA packages. In addition, the entire family is available in 1.7V to 3.6V and 2.5V to 5.5V versions.
