Description

The AT24C128/256 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’s cascadable feature allows up to 4 devices to share a common

Two-wire bus. The device is optimized for use in many automotive applications where

low power and low voltage operation are essential. The devices are available in space-

saving 8-lead JEDEC SOIC and 8-lead TSSOP packages. In addition, the entire family

is available in 2.7V (2.7V to 5.5V) version.
