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 up to 4 devices to share a common Two-wire bus. The device is optimized for use in many industrial and commercial applications where low power and low voltage operation are essential. The devices are available in space-saving 8-lead JEDEC PDIP, 8-lead JEDEC SOIC, 8-lead EIAJ SOIC, 8-lead MAP (24C128), 8-lead TSSOP, 8-lead SOIC Array Package and 8-ball dBGA2 packages. In addition, the entire family is available in 2.7V (2.7V to 5.5V) and 1.8V (1.8V to 3.6V) versions. Featured By RoboticsBD.
