AT24C16C-XHM-T 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; the AT24C16C does not use device address pins. |
| 2 | NC | unconnected | No connect pin with no internal function; the AT24C16C does not use device address pins. |
| 3 | NC | unconnected | No connect pin with no internal function; the AT24C16C does not use device address pins. |
| 4 | GND | power_in | Ground reference for the device. |
| 5 | SDA | bidirectional | Serial data pin for bidirectional data transfer; open-drain driven and may be wire-ORed with other open-drain or open-collector devices. |
| 6 | SCL | input | Serial clock input that positive-edge clocks data into the EEPROM and negative-edge clocks data out. |
| 7 | WP | input | Write protect input: normal read/write operation when connected to GND, and the full array is protected when connected to VCC. |
| 8 | VCC | power_in | Power supply, 1.7V to 5.5V. |
