AT24C64D-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; if left floating it is internally pulled down to GND, and Atmel recommends a pull-up of 10k or less. |
| 2 | A1 | input | Device address input hard wired to GND or VCC; if left floating it is internally pulled down to GND, and Atmel recommends a pull-up of 10k or less. |
| 3 | A2 | input | Device address input hard wired to GND or VCC; if left floating it is internally pulled down to GND, and Atmel recommends a pull-up of 10k or less. |
| 4 | GND | power_in | Ground reference pin for the device. |
| 5 | SDA | bidirectional | Bidirectional serial data pin that is 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 of it. |
| 7 | WP | input | Write Protect input: connected to GND allows normal write operations, while connected directly to VCC all write operations are inhibited. |
| 8 | VCC | power_in | Device power supply; the supply voltage range is specified as 1.7 V to 5.5 V. |
