IIS3DWBTR from STMicroelectronics, in a LGA-14(2.5x3). 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 | SDO/SA0 | bidirectional | SPI 4-wire interface serial data output (SDO). In I2C mode, this pin selects the least significant bit of the device address (SA0). Input without pull-up by default; pull-up enabled if SDO_PU_EN=1 in reg 02h. |
| 2 | RES | passive | Reserved. Connect to VDD_IO or GND. |
| 3 | RES | passive | Reserved. Connect to VDD_IO or GND. |
| 4 | INT1 | output | Programmable interrupt #1. Input with pull-down by default; must be set to 0 or left unconnected during device power-up. After power-up, connection is application specific. |
| 5 | VDD_IO | power_in | Power supply for I/O pins. Operational range 2.1 V to 3.6 V. Recommended 100 nF filter capacitor. |
| 6 | GND | power_in | Ground reference. Connect to GND. |
| 7 | GND | power_in | Ground reference. Connect to GND. |
| 8 | VDD | power_in | Main analog power supply. Operational range 2.1 V to 3.6 V (factory calibrated at 3.0 V). Recommended 100 nF filter capacitor. |
| 9 | INT2 | output | Programmable interrupt #2. Default state: output forced to GND. Application-specific connection. |
| 10 | RES | passive | Reserved. Connect to VDD_IO or leave pin electrically unconnected and soldered to PCB. Input with pull-up by default. |
| 11 | RES | passive | Reserved. Connect to VDD_IO or leave pin electrically unconnected and soldered to PCB. Input with pull-up by default. |
| 12 | CS | input | I2C/SPI mode selection. CS=1: SPI idle mode / I2C communication enabled. CS=0: SPI communication mode / I2C disabled. Input with pull-up by default; pull-up disabled if I2C_DISABLE=1 in reg 13h. |
| 13 | SPC/SCL | input | SPI serial port clock (SPC) / I2C serial clock (SCL). Input without pull-up. |
| 14 | SDI/SDO/SDA | bidirectional | SPI serial data input (SDI) / 3-wire interface serial data output (SDO) / I2C serial data (SDA). Input without pull-up by default. |
