Description  
The Atmel® AT25512 provides 524,288 bits of Serial Electrically Erasable  
Programmable Read-Only Memory (EEPROM) organized as 65,536 words of  
8 bits each. 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 JEDEC SOIC, 8-lead TSSOP, and  
8-pad UDFN packages. In addition, the device operates from 1.8V to 5.5V.  
The AT25512 is enabled through the Chip Select pin (CS) and accessed via a  
3-wire interface consisting of Serial Data Input (SI), Serial Data Output (SO), and  
Serial Clock (SCK). All programming cycles are completely self-timed, and no  
separate erase cycle is required before write.  
Block Write Protection is enabled by programming the status register with top ¼,  
top ½, or entire array of Write Protection. Separate program enable and program  
disable instructions are provided for additional data protection. Hardware Data  
Protection is provided via the WP pin to protect against inadvertent write attempts  
to the status register. The HOLD pin may be used to suspend any serial  
communication without resetting the serial sequence.
