Description

The Atmel® AT24C256C provides 262,144-bits of Serial Electrically Erasable and

Programmable Read-Only Memory (EEPROM) organized as 32,768 words of

8 bits each. The device’s cascading feature 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

TSSOP, 8-pad UDFN, and 8-ball VFBGA packages. In addition, this device

operates from 1.7V to 5.5V.
