Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | A0 | input | Device address input, hard-wired to GND or VCC; it is internally pulled down if left floating, and Microchip recommends a pull-up of 10 kΩ or less when one is used. |
| 2 | A1 | input | Device address input, hard-wired to GND or VCC so that up to eight devices can share one bus; it is internally pulled down if left floating, and Microchip recommends a pull-up of 10 kΩ or less when one is used. |
| 3 | A2 | input | Device address input, hard-wired to GND or VCC so that up to eight devices can share one bus; it is internally pulled down if left floating, and Microchip recommends a pull-up of 10 kΩ or less when one is used. |
| 4 | GND | power_in | Ground reference for the power supply, which should be connected to the system ground. |
| 5 | SDA | bidirectional | Open-drain serial data input/output that must be pulled high through an external pull-up resistor not exceeding 10 kΩ and may be wire-ORed with other open-drain devices on the bus. |
| 6 | SCL | input | Serial clock that latches SDA input on its rising edge and clocks SDA output on its falling edge; it must be held high when the bus is idle, either forced or pulled up by an external resistor. |
| 7 | WP | input | Write-protect input: connecting it to GND allows normal write operations, while connecting it to VCC inhibits all writes to the full array; it is internally pulled down if left floating, and a pull-up of 10 kΩ or less is recommended when used. |
| 8 | VCC | power_in | Device power supply pin; operating at VCC voltages outside the specified range may produce spurious results and should not be attempted. |
