LIS2DTW12TR from STMicroelectronics, in a LGA-12(2x2). 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 | SCL/SPC | bidirectional | I²C serial clock (open-drain) or SPI port clock input; enables clock stretching in I²C mode. |
| 2 | CS | input | SPI chip select; pulled low enables SPI mode, held high to VDD_IO enables I²C mode. |
| 3 | SDO/SA0 | output | SPI serial data output with internal pull-up to VDD; or I²C slave address selection bit (SA0) in I²C mode. |
| 4 | SDA/SDI/SDO | bidirectional | I²C serial data line (open-drain), SPI input data (4-wire mode), or SPI output data (3-wire mode) depending on interface configuration. |
| 5 | NC | unconnected | Internally not connected; may be tied to VDD, VDD_IO, or GND without functional impact. |
| 6 | GND | power_in | Ground (0 V) supply reference. |
| 7 | RES | input | Reset pin; must be connected to GND for normal device operation. |
| 8 | GND | power_in | Ground (0 V) supply reference; provides return path for analog and digital circuits. |
| 9 | VDD | power_in | Analog power supply; operating range 1.62 V to 3.6 V, factory calibrated at 1.8 V typical. |
| 10 | VDD_IO | power_in | Digital I/O buffer power supply; range 1.62 V to (VDD + 0.1 V); independent from VDD to support voltage level translation. |
| 11 | INT2 | bidirectional | Interrupt output pin 2 with push-pull driver; can be configured as clock input trigger in single data conversion on-demand mode. |
| 12 | INT1 | output | Interrupt output pin 1 with push-pull driver; signals motion detection, data-ready, tap, free-fall, and wake-up events. |
