... Description The FM24C32A/64A provides 32,768/65,536 bits of serial electrically erasable and programmable read-only memory (EEPROM) organized as 4096/8192 words of 8 bits each. 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 applications where low-power and low-voltage operations are essential ...
