Description

The AT25HP256/512 provides 262,144/524,288 bits of serial electrically erasable pro­grammable read only memory (EEPROM) organized as 32,768/65,536 words of 8-bits
each. The device is o ptimi zed f or u se i n man y in dustria l and com merc ial app lic ations
where high-speed, low- power, and low-voltage operation are essent ial. The
AT25HP256/512 is available in a space saving 8-pin PDIP (AT25HP256/512), 8-pin
EIAJ SOIC (AT25HP256), and 8-pin Leadless Array (AT25HP256/512) packages. In

addition, the entire family is available in 5.0V (4.5V to

5.5V), 2.7V (2.7V to 5.5V), and 1.8V (1 .8V to 3.6V) ver­sions.

The AT25HP256/512 is enabled through the Chip Select
pin (CS
Serial Data Input (SI), Serial Data Output (SO), and Serial
Clock (SCK). All progr amming cycle s are co mpletely s elf­timed, 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 pro­tection. Separate program enable and program disable
instructions are provided for additional data protection.
Hardware d ata protection is pr ovided via the WP
tect against inadvertent write attempts to the status regis­ter. The HOLD
