AT24C01D-SSHM-T from Microchip Tech, in a SOIC-8-150mil. 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 | A0 | input | Device address input hard-wired to GND or VCC (up to eight devices per bus); internally pulled down to GND if left floating, but connecting it to a known state is recommended. |
| 2 | A1 | input | Device address input hard-wired to GND or VCC (up to eight devices per bus); internally pulled down to GND if left floating, but connecting it to a known state is recommended. |
| 3 | A2 | input | Device address input hard-wired to GND or VCC (up to eight devices per bus); internally pulled down to GND if left floating, but 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 requires an external pull-up resistor not exceeding 10 kΩ and may be wire-ORed with other open-drain devices on the bus. |
| 6 | SCL | input | Serial clock input; commands and data are latched on the rising edge of SCL, output data is clocked out on the falling edge, and it must be forced high or pulled high when the bus is idle. |
| 7 | WP | input | Write-protect input: connected to GND allows normal writes, connected to VCC inhibits all writes to the full array; internally pulled down to GND if left floating. |
| 8 | VCC | power_in | Device power supply, operating from 1.7V to 3.6V; operation at invalid VCC voltages may produce spurious results. |
