AT24C512

Description

The AT24C512 provides 524,288 bits of serial electrically erasable and programmable

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

cascadable feature allows up to 4 devices to share a common 2-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, 20-pin JEDEC SOIC, 8-pin Leadless Array (LAP), and 8-ball dBGA pack-

ages. In addition, the entire family is available in 5.0V (4.5V to 5.5V), 2.7V (2.7V to

5.5V) and 1.8V (1.8V to 3.6V) versions.
