AT24C32E-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 | A0 | input | Device address input hard-wired to GND or VCC for multi-device addressing (up to eight devices per bus); internally pulled down to GND if left unconnected. |
| 2 | A1 | input | Device address input hard-wired to GND or VCC for multi-device addressing (up to eight devices per bus); internally pulled down to GND if left unconnected. |
| 3 | A2 | input | Device address input hard-wired to GND or VCC for multi-device addressing (up to eight devices per bus); internally pulled down to GND if left unconnected. |
| 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 requiring an external pull-up resistor not exceeding 10 kΩ, may be wire-ORed with other open-drain bus pins. |
| 6 | SCL | input | Serial clock input that controls data flow; input data is latched on the rising edge and 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: at GND allows normal writes, at VCC inhibits all writes to the full array; internally pulled down to GND if left floating. |
| 8 | VCC | power_in | Device power supply pin, operating range 1.7V to 3.6V. |
