... JEDEC PDIP, 8-Pin JEDEC and EIAJ SOIC, 14-Pin TSSOP, and 8-Pin Leadless Array Packages Description The AT24C128/256 provides 131,072/262,144 bits of serial electrically erasable and programmable read only memory (EEPROM) organized as 16,384/32,768 words of 8 bits each. The device’s cascadable feature allows devices to share a common 2-wire bus ...
