# LSM6DSOWTR

**STMicroelectronics** · Accelerometers · LGA-14(2.5x3)

LSM6DSOWTR from STMicroelectronics, in a LGA-14(2.5x3). 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 | SDO/SA0 | output | SPI serial data output (SDO) or I2C device address least significant bit (SA0); high when connected to VDDIO, low when connected to GND. |
| 2 | SDx | output | Mode 1: must be connected to VDDIO or GND; Mode 2: I2C master serial data (MSDA). |
| 3 | SCx | output | Mode 1: must be connected to VDDIO or GND; Mode 2: I2C master serial clock (MSCL). |
| 4 | INT1 | output | Programmable interrupt 1 output; must be pulled high when device operates as MIPI I3CSM pure slave. |
| 5 | VDDIO | power_in | I/O power supply (1.62 V minimum independent IO supply) with recommended 100 nF filter capacitor. |
| 6 | GND | power_in | Ground (0 V supply). |
| 7 | GND | power_in | Ground (0 V supply). |
| 8 | VDD | power_in | Analog power supply (1.71 V to 3.6 V) with recommended 100 nF filter capacitor. |
| 9 | INT2 | output | Programmable interrupt 2 (INT2) / Data Enable (DEN) in Mode 1 or I2C master external synchronization signal (MDRDY) in Mode 2. |
| 10 | NC | unconnected | No connection; leave electrically unconnected and soldered to PCB. |
| 11 | NC | unconnected | No connection; leave electrically unconnected and soldered to PCB. |
| 12 | CS | input | I2C/MIPI I3CSM/SPI mode selection: logic 1 enables I2C/MIPI I3CSM, logic 0 enables SPI. |
| 13 | SCL | bidirectional | I2C/MIPI I3CSM serial clock (SCL) with open-drain operation or SPI serial port clock (SPC) slave input. |
| 14 | SDA | bidirectional | I2C/MIPI I3CSM serial data (SDA) with open-drain operation, SPI serial data input (SDI), or 3-wire serial data output. |
