AIS328DQTR

STMicroelectronics · Accelerometers · QFN-24-EP(4x4)

AIS328DQTR from STMicroelectronics, in a QFN-24-EP(4x4). 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	NC	unconnected	Not connected.
2	NC	unconnected	Not connected.
3	INT_2	output	Inertial interrupt 2 output.
4	Reserved	passive	Reserved pin; datasheet requires it to be connected to GND.
5	VDD	power_in	Core power supply, 2.4 V to 3.6 V (3.3 V typical); decoupling capacitors should be placed as near as possible to this pin.
6	GND	power_in	0 V supply.
7	INT_1	output	Inertial interrupt 1 output.
8	GND	power_in	0 V supply.
9	GND	power_in	0 V supply.
10	GND	power_in	0 V supply.
11	SPC / SCL	input	SPI serial port clock (SPC) in SPI mode or I2C serial clock (SCL) in I2C mode, with internal active pull-up.
12	CS	input	I2C/SPI mode selection: 0 enables SPI, 1 selects I2C mode; internal active pull-up.
13	Reserved	passive	Reserved pin; datasheet requires it to be connected to Vdd.
14	VDD_IO	power_in	Power supply for I/O pins, 1.8 V to Vdd+0.1 V.
15	SDO/SA0	bidirectional	SPI serial data output (SDO), or I2C least significant device address bit (SA0) which selects address 0011001b when tied to Vdd and 0011000b when tied to GND; internal active pull-up.
16	SDI / SDO / SDA	bidirectional	SPI serial data input (SDI), 3-wire interface serial data output (SDO), or I2C serial data (SDA); internal active pull-up.
17	NC	unconnected	Not internally connected.
18	NC	unconnected	Not internally connected.
19	NC	unconnected	Not internally connected.
20	NC	unconnected	Not internally connected.
21	NC	unconnected	Not internally connected.
22	NC	unconnected	Not internally connected.
23	NC	unconnected	Not internally connected.
24	NC	unconnected	Not internally connected.
25	EP	passive	Exposed pad (from the footprint; not named in the datasheet pin table).
