Pin Function Grouping

flux

Grouped the ADXL335BCPZ pins by function with no duplicate pin assignments: Power = VS pins, Ground/Common = COM pins, Analog Outputs = XOUT/YOUT/ZOUT, Control = ST, No Connect = NC pins, and Exposed Pad kept separate because it is not internally connected. Full grouping is in the ADXL335BCPZ Pin Function Groups project file.

Add those function groups to the symbol pin organization.

I've made a plan, and started work on it.

Started implementing a plan

#Goal

- Add the previously determined ADXL335BCPZ datasheet-based function groups (Power, Ground/Common, Analog Outputs, Control, No Connect, Exposed Pad) to the part symbol pin organization, ensuring that each pin is assigned to exactly one group and no pin is duplicated.

#Implementation plan

1. Review the ADXL335BCPZ published part project to inspect all terminal elements and their pin properties.

1. Identify and list the pins as per datasheet mappings: VS (Power), COM (Ground/Common), XOUT, YOUT, ZOUT (Analog Outputs), ST (Control), NC (No Connect), and any Exposed Pad if present.

2. Update the symbol pin organization by assigning functional groups:

1. Set the VS pin to group "Power".

2. Set the COM pin to group "Ground/Common".

3. Set the XOUT, YOUT, and ZOUT pins to group "Analog Outputs".

4. Set the ST pin to group "Control".

5. Set the NC pin to group "No Connect".

6. Ensure the Exposed Pad pin (if present) is maintained separately from internal connections.

3. Verify that every terminal is assigned exactly one group and that there are no duplicate assignments across the groups.

1. Perform a review of the symbol properties in the project.

2. Confirm that each functional group is exclusive and accurately reflects the datasheet functions.

#Success criteria

- All pins from the ADXL335BCPZ part are assigned to exactly one corresponding group.

- No pin is duplicated in more than one group.

- The symbol pin organization matches the datasheet-based functional groups as specified.

ADXL335BCPZ

ADXL335BCPZ thumbnail
Accelerometer X, Y, Z Axis ±3g 1.6kHz (X,Y), 550Hz (Z) 16-LFCSP-LQ (4x4)
The ADXL335BCPZ is a small, thin, low-power, complete 3-axis accelerometer with signal-conditioned voltage outputs. It measures acceleration with a minimum full-scale range of ±3 g. The device outputs analog voltages proportional to acceleration in each of the three orthogonal axes (X, Y, and Z).
The accelerometer is designed for low power consumption and high resolution, making it suitable for mobile devices, tilt sensing, motion detection, and vibration monitoring. It operates over a wide temperature range and requires minimal external components, enabling easy integration into compact systems.
Functional Overview
The ADXL335 uses a capacitive sensing structure to detect acceleration. Changes in acceleration result in differential capacitance changes, which are converted into voltage outputs through an internal signal conditioning circuit. Each axis provides an independent analog output that can be directly interfaced with ADC inputs of microcontrollers or other processing units.
Bandwidth for each axis can be adjusted using external capacitors, allowing flexibility depending on application requirements.
