AT24C16C-SSHM-T from Microchip, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | NC | unconnected | No connect. The AT24C16C does not use device address pins; this pin is not internally bonded. |
| 2 | NC | unconnected | No connect. The AT24C16C does not use device address pins; this pin is not internally bonded. |
| 3 | NC | unconnected | No connect. The AT24C16C does not use device address pins; this pin is not internally bonded. |
| 4 | GND | power_in | Ground reference (0V) for the device. |
| 5 | SDA | bidirectional | I2C serial data. Bidirectional open-drain line for serial data transfer; may be wire-ORed with other open-drain / open-collector devices. Requires an external pull-up resistor to VCC. |
| 6 | SCL | input | I2C serial clock input. Positive edge clocks data into the EEPROM; negative edge clocks data out. Schmitt-trigger filtered input. Requires an external pull-up resistor to VCC. |
| 7 | WP | input | Write Protect. Tie to GND for normal read/write operation. Tie to VCC to enable hardware write protection of the full array (per Table 4-1). |
| 8 | VCC | power_in | Power supply input. Operating range 1.7V to 5.5V. Typical supply current 0.4mA read / 2.0mA write at VCC=5V, 100kHz. Standby current 1.0uA (1.7V) / 6.0uA (5.5V) max. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 625 faces against 147 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
