AT24C16C-XHM-B from Microchip Tech, in a TSSOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | NC | unconnected | No connect pin with no internal function stated in the datasheet. |
| 2 | NC | unconnected | No connect pin with no internal function stated in the datasheet. |
| 3 | NC | unconnected | No connect pin with no internal function stated in the datasheet. |
| 4 | GND | power_in | Ground reference for the power supply; should be connected to system ground. |
| 5 | SDA | bidirectional | Open-drain bidirectional serial data pin that needs an external pull-up resistor (not to exceed 10 kΩ) and may be wire-ORed with other open-drain or open-collector bus pins. |
| 6 | SCL | input | Serial clock input; commands and input data on SDA are latched on the rising edge of SCL and output data is clocked out on the falling edge, and SCL must be forced high or pulled high with an external pull-up when the bus is idle. |
| 7 | WP | input | Write-protect input: connected to GND it allows normal writes, connected to VCC it inhibits all writes to the full array, and it is internally pulled down to GND if not driven (10 kΩ or less recommended for any pull-up). |
| 8 | VCC | power_in | Device power supply pin, operating from 1.7V to 5.5V. |
