ATSHA204A-SSHCZ-T from Microchip Tech, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | NC | unconnected | No connect. Not internally bonded; may be left floating or tied to any potential. |
| 2 | NC | unconnected | No connect. Not internally bonded; may be left floating or tied to any potential. |
| 3 | NC | unconnected | No connect. Not internally bonded; may be left floating or tied to any potential. |
| 4 | GND | power_in | Ground reference (0 V) for the device. |
| 5 | SDA | bidirectional | Serial Data. On this -CZ (Single-Wire Interface) variant, SDA is the sole open-drain bidirectional data line carrying the UART-compatible high-speed single-wire protocol between host and device. Requires an external pull-up resistor. Communications voltage range 1.8 V to 5.5 V. |
| 6 | SCL | unconnected | Serial Clock Input pin on the physical SOIC-8 package. On the -CZ (Single-Wire Interface) variant this pin is not used by the SWI protocol and can be left unconnected. |
| 7 | NC | unconnected | No connect. Not internally bonded; may be left floating or tied to any potential. |
| 8 | VCC | power_in | Power supply input. Operating supply voltage 2.0 V to 5.5 V. Sleep current <150 nA. Bypass with a local ceramic decoupling capacitor to GND. |
