2.1

No Connect

The NC pins are not internally connected. These pins can be connected to GND or left floating.

2.2

Serial Input and Output

The SI/O pin is an open-drain, bidirectional input/output pin used to serially transfer data to and from the

device.

The SI/O pin must be pulled high using an external pull

‑up resistor (not to exceed 4 kΩ in value) and may

be wire-ORed with any number of other open

‑drain or open‑collector pins from other devices on the same

bus.

The device also uses the SI/O pin as its voltage source by drawing and storing power during the periods

that the pin is pulled high to a voltage level between 1.7V and 3.6V (AT21CS01) and between 2.7V and

4.5V (AT21CS11).
