... The device’s cascadable feature allows devices to share a common 2- wire bus. The device is optimized for use in many industrial and commercial applica- tions where low power and low voltage operation are essential. The AT24C32C/64C is available in space saving 8-lead PDIP, 8-lead JEDEC SOIC, 8-lead TSSOP, 8-lead Ultra Thin Mini-MAP (MLP2x3) and, 8-ball dBGA2 packages and is accessed via a 2- wire serial interface ...
