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

LSM6DSO16ISTR 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 | bidirectional | Mode 1: SPI 4-wire serial data output (SDO); Mode 2: I²C least significant bit of the device address (SA0), where SA0 tied to VDD selects address 1101011b and tied to GND selects 1101010b; default is input without pull-up, with pull-up enabled by SDO_PU_EN in PIN_CTRL (02h). |
| 2 | MSDA | bidirectional | Mode 1: connect to Vdd_IO or GND; Mode 2: I²C serial data line of the master interface (MSDA), default input without pull-up, with pull-up enabled by SHUB_PU_EN in MASTER_CONFIG (14h). |
| 3 | MSCL | bidirectional | Mode 1: connect to Vdd_IO or GND; Mode 2: I²C serial clock of the master interface (MSCL), default input without pull-up, with pull-up enabled by SHUB_PU_EN in MASTER_CONFIG (14h). |
| 4 | INT1 | bidirectional | Programmable interrupt 1 in both modes; default is input with pull-down, and INT1 must be set to 0 or left unconnected during power-on. |
| 5 | Vdd_IO | power_in | Power supply for the I/O pins; a 100 nF filter capacitor is recommended. |
| 6 | GND | power_in | 0 V supply. |
| 7 | GND | power_in | 0 V supply. |
| 8 | Vdd | power_in | Power supply for the device core and analog circuitry; a 100 nF filter capacitor is recommended, placed as near as possible to the pin, and the analog supply range is stated as 1.71 V to 3.6 V. |
| 9 | INT2 | bidirectional | Mode 1: programmable interrupt 2 (INT2); Mode 2: programmable interrupt 2 (INT2) multiplexed with the I²C master external synchronization signal (MDRDY); default output is forced to ground. |
| 10 | RES | unconnected | Reserved; leave electrically unconnected (pin is soldered to the PCB). |
| 11 | RES | passive | Reserved; connect to Vdd_IO or leave electrically unconnected (pin is soldered to the PCB). |
| 12 | CS | input | I²C/SPI mode selection: 1 selects SPI idle mode with I²C communication enabled, 0 selects SPI communication mode with I²C disabled; default input with pull-up. |
| 13 | SCL | input | I²C serial clock (SCL) or SPI serial port clock (SPC); default input without pull-up. |
| 14 | SDA | bidirectional | I²C serial data (SDA), SPI serial data input (SDI), or 3-wire interface serial data output (SDO); default input without pull-up. |
