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-pin PDIP (AT25HP256/512), 8-pin
EIAJ SOIC (AT25HP256), and 8-pin Leadless Array (AT25HP256/512) packages. In
