AIS2DW12TR 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 | tri_state | I²C serial clock line (open-drain) or SPI serial port clock; operates as bidirectional clock in I²C mode and input in SPI mode. |
| 2 | CS | input | SPI chip select (active low) and I²C/SPI mode selection pin (1: SPI idle/I²C enabled, 0: SPI communication); internally pulled high. |
| 3 | SDO/SA0 | bidirectional | SPI serial data output (SDO) in SPI mode or I²C device address selection bit (SA0) in I²C mode; internally pulled high. |
| 4 | SDA/SDI/SDO | tri_state | I²C serial data line (SDA, open-drain) in I²C mode, SPI serial data input (SDI) in SPI 4-wire mode, or 3-wire serial data output (SDO); open-drain in I²C mode. |
| 5 | NC | unconnected | Not internally connected; can be tied to VDD, VDDIO, or GND without affecting device operation. |
| 6 | GND | power_in | Ground reference voltage (0 V) for core and analog circuits. |
| 7 | RES | input | Reset pin (active low); must be connected to ground (GND) for normal operation. |
| 8 | GND | power_in | Ground reference voltage (0 V) for I/O circuits. |
| 9 | VDD | power_in | Main power supply input for accelerometer core; operating voltage range 1.62 V to 3.6 V per Table 5. |
| 10 | VDD_IO | power_in | Power supply for I/O pins; operating voltage range 1.62 V to Vdd+0.1 V; can be maintained independently while main VDD is removed without blocking communication bus. |
| 11 | INT2 | bidirectional | Interrupt output pin 2 (push-pull); can be configured as external clock input for single data conversion on-demand mode operation per section 3.2.2. |
| 12 | INT1 | output | Interrupt output pin 1 (push-pull); indicates data-ready, wakeup, free-fall, FIFO threshold, or 6D orientation change events based on CTRL4_INT1 register configuration. |
