SPI Serial EEPROMs

Atmel Corporation 

The AT25P1024 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 separate 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 pro-

tection. Separate program enable and program disable

instructions are provided for additional data protection.

Hardware data protection is provided via the WP pin to pro-

tect against inadvertent write attempts to the status regis-

ter. The HOLD pin may be used to suspend any serial

communication without resetting the serial sequence.
