Description
The AT24C128B provides 131,072 bits of serial electrically erasable and programma-
ble read-only memory (EEPROM) organized as 16,384 words of 8 bits each. The
device’s cascadable feature allows up to eight 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 Ultra Thin Mini
MAP, 8-lead Ultra Thin SAP, 8-lead TSSOP, and 8-ball dBGA2 packages. In addition,
the entire family is available in a 1.8V (1.8V to 3.6V) version.
