Description

The Atmel® AT24C01C/02C provides 1024/2048-bits of Serial Electrically Erasable and

Programmable Read-Only Memory (EEPROM) organized as 128/256 words of eight

bits each. Both devices include a cascading feature that allows up to eight devices to

share a common 2-wire bus. These devices are optimized for use in many industrial

and commercial applications where low power and low voltage operation are essential.

The AT24C01C/02C are available in space saving 8-lead PDIP, 8-lead JEDEC SOIC,

8-lead TSSOP, 8-lead UDFN, 5-lead SOT23, and 8-ball VFBGA packages. In addition,

the entire family operates from 1.7V to 5.5V VCC.
