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.
