Small Array (SAP), and 8-ball dBGA2 Packages

Description

The AT24C1024B provides 1,048,576 bits of serial electrically erasable and program-

mable read only memory (EEPROM) organized as 131,072 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-lead PDIP, 8-lead JEDEC SOIC, 8-lead EIAJ SOIC, 8-lead TSSOP,

8-ball dBGA2 and 8-lead Ultra Thin SAP packages. In addition, the entire family is

available in 1.8V (1.8V to 3.6V) and 2.5V (2.5V to 5.5V) versions.
