LIS2DE12TR 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 | input | I2C serial clock (SCL) input in I2C mode or SPI serial port clock (SPC) input in SPI mode. |
| 2 | CS | input | SPI chip select enable and I2C/SPI mode selection input (high for I2C enabled, low for SPI enabled). |
| 3 | SDO/SA0 | bidirectional | SPI serial data output (SDO) or I2C slave address least significant bit (SA0) with internal pull-up of 20.4 to 54.4 kΩ depending on Vdd_IO supply voltage. |
| 4 | SDA/SDI/SDO | bidirectional | I2C serial data (SDA) bidirectional, SPI serial data input (SDI), or 3-wire SPI serial data output (SDO) depending on interface mode configuration. |
| 5 | Res | passive | Reserved pin that must be connected to ground (GND). |
| 6 | GND | power_in | Ground reference (0 V) connection. |
| 7 | GND | power_in | Ground reference (0 V) connection. |
| 8 | GND | power_in | Ground reference (0 V) connection. |
| 9 | Vdd | power_in | Analog and core power supply with 1.71 V to 3.6 V operating range, requires 100 nF ceramic and 10 μF aluminum decoupling capacitors placed near this pin. |
| 10 | Vdd_IO | power_in | I/O power supply with 1.71 V to Vdd+0.1 V operating range that can be maintained independently of Vdd without blocking communication buses. |
| 11 | INT2 | output | Programmable interrupt output pin 2 for motion detection and free-fall events, active high by default (polarity configurable via CTRL_REG6 bit 7). |
| 12 | INT1 | output | Programmable interrupt output pin 1 for motion detection and free-fall events, active high by default (polarity configurable via CTRL_REG3 bit 7). |
