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.
