Description
The AT25HP256/512 provides 262,144/524,288 bits of serial electrically erasable pro-
grammable read only memory (EEPROM) organized as 32,768/65,536 words of 8-bits
each. The device is optimized for use in many industrial and commercial applications
where high-speed, low-power, and low-voltage operation are essential. The
AT25HP256/512 is available in a space saving 8-lead PDIP (AT25HP256/512), 8-lead
EIAJ SOIC (AT25HP256), 16-lead JEDEC SOIC (AT25HP512), 8-lead Leadless Array
(AT25HP256/512) package, and 8-lead SOIC Array package (SAP). In addition, the
entire family is available in 2.7V (2.7V to 5.5V) and 1.8V (1.8V to 5.5V) versions.

AT25HP256/512
1113L–SEEPR–3/06
The AT25HP256/512 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 protection. Separate Program Enable and Program Disable
instructions are provided for additional data protection. Hardware data protection is pro-
vided 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.
