LIS2DS12TR from STMicroelectronics, in a LGA-12(2x2). 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 | SCL/SPC | input | I2C serial clock (SCL) or SPI serial port clock (SPC); receives clock input from master; supports I2C fast mode (400 kHz) and normal mode. |
| 2 | CS | input | Chip select for SPI enable and I2C/SPI mode selection; high for I2C communication and SPI idle mode, low for SPI communication; has active pull-up and can be left unconnected. |
| 3 | SDO/SA0 | output | SPI serial data output (SDO) in SPI mode or I2C device address least significant bit (SA0) in I2C mode; SA0 selection determined by external connection to Vdd_IO for address 0011101b or GND for address 0011110b. |
| 4 | SDA/SDI/SDO | bidirectional | I2C serial data (SDA) bidirectional line in I2C mode, SPI serial data input (SDI) in 4-wire SPI mode, or SPI 3-wire interface serial data output (SDO); open-drain configuration in I2C mode. |
| 5 | NC | unconnected | Internally not connected; can be tied to Vdd, Vdd_IO, or GND. |
| 6 | GND | power_in | Ground (0 V reference); must be present simultaneously with Vdd and Vdd_IO for proper IC operation. |
| 7 | RES | input | Reset input (active low); connect to GND for normal operation. |
| 8 | GND | power_in | Ground (0 V reference); must be present simultaneously with Vdd and Vdd_IO for proper IC operation. |
| 9 | Vdd | power_in | Power supply for device core; supply voltage range 1.62 V to 1.98 V; requires 100 nF ceramic and 10 μF aluminum decoupling capacitors placed near this pin. |
| 10 | Vdd_IO | power_in | Power supply for I/O pins; supply voltage range 1.62 V to Vdd+0.1 V; can be maintained without Vdd for I2C/SPI communication when measurement chain is powered off. |
| 11 | INT2 | output | Interrupt pin 2; output signal for interrupt events; functions as I2C clock master line (MSCL) when sensor hub is used and can be internally pulled up through TUD_EN bit of FUNC_CTRL register. |
| 12 | INT1 | output | Interrupt pin 1; output signal for interrupt events generated by device functions. |
