Description
The AT25128 provides 131,072 bits of serial electrically erasable programmable read only memory (EEPROM) organized as 16,384 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 AT25128 is available in space saving 8-pin PDIP, JEDEC SOIC, and 14-pin and 20-pin TSSOP packages.
