... Description The AT24C32A/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 two- wire bus. The device is optimized for use in many industrial and commercial applica- tions where low power and low voltage operation are essential ...

... Device Addressing section). If the pins are left floating, the A2, A1 and A0 pins will be internally pulled down to GND if the capacitive coupling to the circuit board V <3 pF. If coupling is >3 pF, Atmel recommends connecting the address pins to GND. WRITE PROTECT (WP): The write protect input, when connected to GND, allows nor- mal write operations ...
