Procurement Notes

Verify current availability and lead times directly with authorized distributors or Microchip Technology, as development boards may have limited production runs. Confirm that the specific revision matches your target IC variant (QT113 or QT113X). Check for any required accessories such as batteries or jumpers not included in the base package. Ensure compliance with regional regulatory standards if deploying in final products.

Selection Notes

Select the QT113-D when evaluating the QT113 family of capacitive touch sensors. This board is suitable for initial hardware validation and software configuration testing. Consider the QT113X variant if additional features or pin configurations are required. Ensure compatibility with your target microcontroller interface if integrating into a larger system. Review the datasheet for specific component values and jumper settings.

Part Context

The QT113-D belongs to Microchip's QTouch development tool lineup, specifically targeting the QT113 series of charge-transfer touch sensors. These tools are intended for engineers developing touch-sensitive user interfaces. The board simplifies the learning curve for QTouch technology by providing a pre-configured hardware platform. It complements the broader ecosystem of Microchip's embedded control and touch sensing solutions.

Replacement Considerations

No direct replacement part numbers are publicly documented for this specific evaluation board. Alternative evaluation platforms from other vendors may offer similar functionality but will require different configuration and software support.
