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 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 EIAJ SOIC, 8-lead JEDEC SOIC, 8-lead TSSOP, 8-lead
Leadless Array (LAP), and 8-lead SAP packages. In addition, the entire family is avail-
able in 2.7V (2.7V to 5.5V) and 1.8V (1.8V to 3.6V) versions.
