Description  
2K (256 x 8)  
The AT25010/020/040 provides 1024/2048/4096 bits of serial electrically erasable  
programmable read only memory (EEPROM) organized as 128/256/512 words of 8  
bits each. The device is optimized for use in many automotive applications where low-  
power and low voltage operation are essential. The AT25010/020/040 is available in  
space saving 8-pin PDIP and 8-lead JEDEC (SOIC) packages.

The AT25010/020/040 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 sepa-  
rate ERASE cycle is required before WRITE.  
BLOCK WRITE protection is enabled by programming the status register with one of  
four blocks of write protection. Separate program enable and program disable instruc-  
tions are provided for additional data protection. Hardware data protection is provided  
via the WP pin to protect against inadvertent write attempts. The HOLD pin may be  
used to suspend any serial communication without resetting the serial sequence.
