AT24C512B

with Three Device

Address Inputs

Description

The AT24C512B provides 524,288 bits of serial electrically erasable and programma-

ble read only memory (EEPROM) organized as 65,536 words of 8 bits each. The

device’s cascadable feature allows up to four devices to share a common two-wire

bus. The device is optimized for use in many industrial and commercial applications

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

space-saving 8-pin PDIP, 8-lead JEDEC SOIC, 8-lead TSSOP, 8-lead Leadless Array

(LAP), and 8-lead SAP packages. In addition, the entire family is available in a 1.8V

(1.8V to 3.6V) version.
