Description

The Atmel^®AT24C128C/256C provides 131,072/262,144 bits of Serial Electrically

Erasable and Programmable Read-Only Memory (EEPROM) organized as

16,384/32,768 words of 8 bits each. The device is optimized for use in many

automotive applications where low-power and low-voltage operation are essential.

AT24C128C/256C is available in space-saving 8-lead JEDEC SOIC, 8-lead

TSSOP, and 8-pad UDFN packages and is accessed via a 2-wire serial interface.

This device operates from 2.5V to 5.5V for Grade 1 or 1.7V to 5.5V for Grades 2⁽¹⁾

and 3.
