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 industrial and commercial appli-

cations where low power and low voltage operation are essential. The devices are

available in space-saving 8-lead JEDEC PDIP, 8-lead JEDEC SOIC, 8-lead EIAJ

SOIC, 8-lead MAP (24C128), 8-lead TSSOP, 8-lead SOIC Array Package and 8-ball

dBGA2 packages. In addition, the entire family is available in 2.7V (2.7V to 5.5V) and

1.8V (1.8V to 3.6V) versions.
