AT24C04C-SSHM-B from Microchip Tech, in a SOIC-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. |
| 2 | A1 | input | Device address input hardwired to GND or VCC on the AT24C04C (NC on AT24C08C); if left floating it is internally pulled down to GND, and connecting it to a known state is recommended. |
| 3 | A2 | input | Device address input hardwired to GND or VCC; if left floating it is internally pulled down to GND, and connecting it to a known state is recommended. |
| 4 | GND | power_in | Ground reference for the power supply, to be connected to system ground. |
| 5 | SDA | bidirectional | Open-drain bidirectional serial data pin that needs an external pull-up resistor not exceeding 10 kΩ. |
| 6 | SCL | input | Serial clock input that latches command and input data on the rising edge and clocks output data out on the falling edge; it must be forced high or pulled high when the bus is idle. |
| 7 | WP | input | Write-protect input: at GND it allows normal write operations, and at VCC it inhibits all writes to the full array; if left floating it is internally pulled down to GND. |
| 8 | VCC | power_in | Device power supply pin, operating from 1.7V to 5.5V. |
