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 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.  
Note: Not recommended for new  
design; please refer to
