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 V CC .
