Description  
The AT25010A/020A/040A provides 1024/2048/4096 bits of serial electrically eras-  
able programmable read only memory (EEPROM) organized as 128/256/512 words of  
8 bits each. The device is optimized for use in many industrial and commercial appli-  
cations where low-power and low voltage operation are essential. The  
AT25010A/020A/040A is available in space saving 8-lead PDIP, 8-lead JEDEC SOIC,  
8-lead MAP and 8-lead TSSOP packages.  
AT25010A  
AT25020A  
AT25040A  
The AT25010A/020A/040A 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.  
Preliminary  
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.
