ATECC608B-SSHDA-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 Pin 1 is a no-connect on the 8-lead SOIC and should be left unconnected.
2 NC unconnected Pin 2 is a no-connect on the 8-lead SOIC and should be left unconnected.
3 NC unconnected Pin 3 is a no-connect on the 8-lead SOIC and should be left unconnected.
4 GND power_in Ground reference for the device supply and I/O levels.
5 SDA bidirectional Serial data line of the standard I2C interface, supporting clock rates up to 1 MHz.
6 SCL input Serial clock input of the standard I2C interface, supporting clock rates up to 1 MHz.
7 NC unconnected Pin 7 is a no-connect on the 8-lead SOIC and should be left unconnected.
8 VCC power_in Supply pin with a 2.0V to 5.5V supply voltage range and 1.8V to 5.5V I/O levels.
