ADXL354BEZ Pin Function Groups

Source: Analog Devices ADXL354/ADXL355 datasheet, Table 8: ADXL354 Pin Function Descriptions.

I grouped each physical pin exactly once, using the datasheet pin name/function as the source of truth.

Recommended pin groups

Table

Group	Pins	Common function
Power	5 `VDDIO`; 8 `V1P8DIG`; 10 `V1P8ANA`; 11 `VSUPPLY`	Supply rails / regulator-related supplies
Ground	6 `VSSIO`; 9 `VSS`	Digital and analog ground returns
Analog Outputs	4 `TEMP`; 12 `XOUT`; 13 `YOUT`; 14 `ZOUT`	Sensor output signals: temperature plus X/Y/Z acceleration outputs
Control / Mode Select	1 `RANGE`; 7 `STBY`	Device configuration / operating-mode selection
Self Test	2 `ST1`; 3 `ST2`	Self-test control inputs

Per-pin classification

Table

Pin No.	Mnemonic	Section	Pin Group	Suggested Pin Type	Notes
1	`RANGE`	Control	Control / Mode Select	Input	Range selection pin; tied to ground or `VDDIO` depending range selection.
2	`ST1`	Control	Self Test	Input	Enables self-test mode; force low when not in self-test mode.
3	`ST2`	Control	Self Test	Input	Activates electromechanical self-test actuation; force low when not in self-test mode.
4	`TEMP`	Analog	Analog Outputs	Output	Temperature sensor output.
5	`VDDIO`	Power	Power	Power In	Digital interface supply voltage.
6	`VSSIO`	Ground	Ground	Ground	Digital ground.
7	`STBY`	Control	Control / Mode Select	Input	Standby/measurement mode selection.
8	`V1P8DIG`	Power	Power	Power In	Digital supply; requires decoupling capacitor.
9	`VSS`	Ground	Ground	Ground	Analog ground.
10	`V1P8ANA`	Power	Power	Power In	Analog supply; requires decoupling capacitor.
11	`VSUPPLY`	Power	Power	Power In	Main supply; can feed internal LDO regulators for the 1.8 V rails.
12	`XOUT`	Analog	Analog Outputs	Output	X-axis analog output.
13	`YOUT`	Analog	Analog Outputs	Output	Y-axis analog output.
14	`ZOUT`	Analog	Analog Outputs	Output	Z-axis analog output.

Notes

I did not duplicate any pin across groups.
I kept TEMP with the analog outputs because it is an analog sensor output, not a power/control pin.
I kept ST1 and ST2 separate from general control because the datasheet gives them a shared self-test function.
I grouped RANGE and STBY together as mode/configuration control pins.
The package is 14 pins; no exposed pad or no-connect pin was identified in the extracted ADXL354 pin function table.
