Engineering Scope
Low-power product programming and production test development are used to solve specific engineering problems in low-power projects. The work starts from the customer's existing design and business requirements, and develops programming, identity writing, sleep check, dynamic current detection and traceability; the tooling software, operating procedures, limit configuration and batch recording format are delivered according to the agreed modules.
Check input with baseline
Check the mass production version, fixture interface, programming tools, test items and limits, and clarify the scope of measurement and modification.
Implementation and adaptation
Develop programming, identity writing, sleep check, dynamic current detection and tracing, and record solution choices and dependency conditions.
Target environment joint debugging
Use representative samples and known fault boards to verify test repeatability and detection capabilities, and confirm business behavior after parameter changes.
Document and record delivery
Provide tooling software, operating procedures, limit configurations and batch record formats, and describe versions, construction or usage methods.
Project Workflow
- Input confirmation: mass production version, fixture interface, programming tool, test items and limits.
- Implementation method: development and burning, identity writing, sleep check, dynamic current detection and traceability.
- Stage review: Use representative samples and known failed boards to verify test repeatability and detection capabilities.
- Project delivery: tooling software, operating procedures, limit configuration and batch record format.
Design Conditions and Functional Limits
It is also necessary to cover start-up, wireless or actuator peak and wake-up functions by risk, otherwise products that are in normal standby but do not work may be missed.
Special services take the agreed module as the implementation boundary. When hardware modifications, third-party agreements, overall platforms or external tests are involved, the interfaces, workload and responsibilities are confirmed separately, and local modifications are not directly used as conclusions on the performance of the complete device.
Project Inputs
- Mass production version, fixture interface, programming tools, test items and limits.
- Existing prototypes and reproducible problems, or new project functionality and power consumption targets.
- Modified design, source code and third-party dependencies are allowed; functionality and compatibility need to be maintained.
- Delivery list, target environment, sample scope, project milestones and acceptance methods.
Delivery and Acceptance
| Delivery content | Check method |
|---|---|
| Tooling software, operating procedures, limit configuration and batch record format | Check the editability, version, usage instructions and dependencies by file list. |
| Implementation verification | Use representative samples and known fault boards to verify test repeatability and detection capabilities, and retain corresponding working conditions and results. |
| Comparison of functions and power consumption | Fixed applicable hardware, software, battery, temperature and business cycles, accounting for changes in conditions and their impact. |
| Reproduction and follow-up maintenance | Provide build or run steps, known limitations, parameter ranges, and uncovered cases. |
Frequently Asked Questions
The production test only checks whether the sleep current is sufficient?+
It is also necessary to cover start-up, wireless or actuator peak and wake-up functions by risk, otherwise products that are in normal standby but do not work may be missed.
What information do I need to prepare before starting the project?+
This work focuses on the mass production version, fixture interface, programming tools, test items and limits. When the data is incomplete, first determine the scope that needs supplementary testing or sorting out, and then proceed to implementation.
Can it be implemented together with the complete device development project?+
It can be used as a work package in the overall project, or it can be implemented separately for existing products. It is necessary to explain the interfaces with other modules, versions and final machine verification responsibilities.

The configuration of GPIO should be checked together with the external circuit, sleep mode and wake-up status; the actual parameters are subject to the target chip data and the whole board test. GPIO and power state design reference
