Plan

#Goal

Update the ADXL335BCPZ-RL7 project to ensure that each terminal is assigned exactly one functional group, in strict alignment with the official ADXL335 datasheet. Each pin will be uniquely grouped (e.g. Power, Ground, Analog Outputs, Self-Test, No Connect, Exposed Pad) with no duplicate group membership.

#Implementation plan

Extract and verify the official ADXL335 datasheet pinout from https://www.analog.com/media/en/technical-documentation/data-sheets/ADXL335.pdf.
1. Identify each pin's function and corresponding terminal property in the datasheet.
Audit the current terminal assignments on the ADXL335BCPZ-RL7 project, referencing the current mapping:
- NC@1=1, ST=2, COM@1=3, NC@2=4, COM@2=5, COM@3=6, COM@4=7, ZOUT=8, NC@3=9, YOUT=10, NC@4=11, XOUT=12, NC@5=13, VS@1=14, VS@2=15, NC@6=16, EP=EP.
Define unique functional groups based on datasheet functions:
1. Assign Power (VS) group to pins VS@1 and VS@2.
2. Assign Ground group for the COM pins (COM@1, COM@2, COM@3, COM@4).
3. Assign Analog Outputs group to XOUT, YOUT, and ZOUT.
4. Assign Self-Test group to the ST pin.
5. Assign No Connect group to all NC pins (NC@1, NC@2, NC@3, NC@4, NC@5, NC@6).
6. Assign Exposed Pad group to the EP terminal.
Modify the terminal properties in the project:
1. Update or add properties such as Section, Pin Group, Pin Description, and Pin Type to reflect the unique assignment for each terminal.
2. Ensure each terminal belongs to one and only one functional group based on the defined mapping.
Verify the updated properties for accuracy and completeness against the datasheet to ensure no pin is unassigned or doubly assigned.

#Success criteria

Each terminal in the ADXL335BCPZ-RL7 part project is assigned exactly one functional group corresponding to its datasheet function.
The terminal groups are clearly defined as Power, Ground, Analog Outputs, Self-Test, No Connect, and Exposed Pad with no duplicate membership.
Verification confirms that all physical pins from the datasheet are represented exactly once in the updated terminal mapping.

Verification result

All 16 package pins plus EP are represented exactly once.
Each terminal has exactly one Section and one Pin Group.
Functional groups used: Power, Ground, Analog Outputs, Self-Test, No Connect, Exposed Pad.
No terminal is assigned to multiple groups.
EP is grouped separately as Exposed Pad and left as Not Connected because the datasheet states it is not internally connected and should be soldered for mechanical integrity.

Project Name

ADXL335BCPZ-RL7

Description

Accelerometer X, Y, Z Axis ±3g 1.6kHz (X,Y), 550Hz (Z) 16-LFCSP-LQ (4x4)

The ADXL335BCPZ-RL7 is a low-power, complete 3-axis accelerometer with analog voltage outputs proportional to acceleration. It measures acceleration along the X, Y, and Z axes with a full-scale range of ±3 g.

This device integrates a micro-electromechanical system (MEMS) sensor with signal conditioning circuitry, enabling direct analog output without the need for external amplification. The RL7 suffix indicates tape-and-reel packaging for automated assembly.

The ADXL335BCPZ-RL7 is designed for compact, battery-powered, and motion-sensitive applications where low power consumption and ease of integration are critical.

Functional Overview

The accelerometer operates using a capacitive sensing structure. Acceleration causes displacement of an internal mass, changing capacitance, which is converted into a proportional analog voltage output.

Each axis operates independently and provides a continuous analog signal that can be read by a microcontroller’s ADC. External capacitors allow the user to configure bandwidth per axis, enabling optimization for noise or response speed.

Axes: Three independent outputs (XOUT, YOUT, ZOUT)

Output Impedance: Approximately 32 kΩ

Noise Density: X/Y axes: ~150 µg/√Hz Z axis: ~300 µg/√Hz

Mechanical Characteristics

Package Type: 16-lead LFCSP

Package Dimensions: Approximately 4 mm × 4 mm × 1.45 mm

Mounting: Surface mount

Packaging Option: Tape and reel (RL7)

Environmental Specifications

Operating Temperature Range: −40°C to +85°C

Storage Temperature Range: −65°C to +150°C

Pin Description (Summary)

ST: Self-test input XOUT: X-axis analog output YOUT: Y-axis analog output ZOUT: Z-axis analog output VCC: Power supply GND: Ground NC: No connection / reserved

Applications

Tilt and orientation sensing Motion and vibration detection Portable electronics Gaming controllers Wearable devices Industrial monitoring systems

Key Features

Three-axis acceleration measurement Low power consumption Analog output for simple interfacing Compact MEMS package Adjustable bandwidth Wide temperature operating range Tape-and-reel packaging for automated manufacturing
