Pins (datasheet Pin Descriptions)

Pin Name Function
1 A0 Device address bit 0; internal pull-down (open = GND)
2 A1 Device address bit 1; internal pull-down
3 A2 Device address bit 2; internal pull-down
4 GND Ground, 0 V reference
5 SDA Serial data, open drain; needs a pull-up
6 SCL Serial clock input, noise filtered
7 WP Write protect: high blocks writes; internal pull-down (open = writable)
8 VCC Supply 1.7 V to 5.5 V; bypass close to the pin
