Description
The AT25P1024 provides 1,048,576 bits of serial electrically erasable programmable
read only memory (EEPROM) organized as 131,072 words of 8 bits each. The device
is optimized for use in many industrial and commercial applications where low power
and low voltage operation are essential. The AT25P1024 is available in space saving
20-pin JEDEC SOIC and 8-pin leadless array (LAP) packages.
