Description
The AT25128A/256A provides 131,072/262,144 bits of serial electrically-erasable pro-
grammable read only memory (EEPROM) organized as 16,384/32,768 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 PDIP, 8-lead EIAJ SOIC, 8-lead JEDEC SOIC, 8-lead TSSOP,
8-ball dBGA2 and 8-lead SAP packages. In addition, the entire family is available in
2.7V (2.7V to 5.5V) and 1.8V (1.8V to 5.5V) versions.
The AT25128A/256A 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 top ¼, top ½ or entire
array of write protection. Separate Program Enable and Program Disable instructions are pro-
vided 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.
