Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | A0 | input | Device address input hard-wired to set the A0 bit of the device address; it must match the device address word for the part to acknowledge, allowing up to eight devices on one bus. |
| 2 | A1 | input | Device address input hard-wired to set the A1 bit of the device address; it must match the device address word for the part to acknowledge, allowing up to eight devices on one bus. |
| 3 | A2 | input | Device address input hard-wired to set the A2 bit of the device address; it must match the device address word for the part to acknowledge, allowing up to eight devices on one bus. |
| 4 | GND | power_in | Ground reference for the device; the WP pin connected to GND selects normal read/write operation. |
| 5 | SDA | bidirectional | Open-drain serial data pin for bidirectional 2-wire transfer that may be wire-ORed with other open-drain or open-collector devices. |
| 6 | SCL | input | Serial clock input: data is clocked into the device on the positive edge of SCL and clocked out on the negative edge. |
| 7 | WP | input | Write Protect input: connecting to GND allows normal read/write operations, while connecting to VCC enables write protection of the entire (2K) array. |
| 8 | VCC | power_in | Power supply, operating from 1.7V to 5.5V per the recommended operating range. |
