AT25F512A  
Description  
The AT25F512A provides 524,288 bits of serial reprogrammable Flash memory orga-  
nized 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 AT25F512A is available in a space-saving 8-lead JEDEC SOIC and  
8-lead SAP packages.  
The AT25F512A is enabled through the Chip Select pin (CS) and accessed via a  
three-wire interface consisting of Serial Data Input (SI), Serial Data Output (SO), and  
Serial Clock (SCK). All write cycles are completely self-timed.  
Block write protection for the entire memory array is enabled by programming the sta-  
tus register. Separate write enable and write disable instructions are provided for  
additional data protection. Hardware data protection is provided via the Write Protect  
(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.
