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-

AT25010A/020A/040A is available in space saving 8-lead PDIP, 8-lead JEDEC SOIC,

8-lead Ultra Thin

The AT25010A/020A/040A 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 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 one of four

blocks 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. The HOLD pin may be used

to suspend any serial communication without resetting the serial sequence.
