IIS2DHTR

STMicroelectronics · Global Sourcing Parts · LGA-12(2x2)

IIS2DHTR 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) in I2C mode and SPI serial port clock (SPC) in SPI mode, with both interfaces sharing this pad; the I2C lines must be pulled up to Vdd_IO through an external resistor.
2 CS input SPI enable and I2C/SPI mode selection: tie high (to Vdd_IO) to enable I2C, and drive low to select SPI communication with I2C disabled.
3 SDO/SA0 bidirectional In I2C mode this pad sets the least significant bit of the device address (SA0; connected to Vdd gives 0011001b, connected to GND gives 0011000b), and in SPI mode it is the SPI serial data output (SDO).
4 SDA/SDI/SDO bidirectional I2C serial data (SDA) in I2C mode, SPI serial data input (SDI) in 4-wire SPI mode, or 3-wire interface serial data output (SDO) in 3-wire SPI mode.
5 Res passive Reserved pin that must be connected to GND.
6 GND power_in 0 V supply, to be connected to ground.
7 GND power_in 0 V supply, to be connected to ground.
8 GND power_in 0 V supply, to be connected to ground.
9 Vdd power_in Power supply; the operational supply range is 1.71 V to 3.6 V.
10 Vdd_IO power_in Power supply for the I/O pins, which supports a 1.8 V I/O supply independent of Vdd.
11 INT2 output Interrupt pin 2, driven by the second independent programmable interrupt generator (free-fall, motion, or position detection).
12 INT1 output Interrupt pin 1, driven by the first independent programmable interrupt generator (free-fall, motion, or position detection).
