Overview
The CAP1005-1-AIA-TR is a five-channel capacitive touch sensor IC manufactured by Microchip Technology. It features a full-duplex SPI communication interface and operates within a 3V to 3.6V supply voltage range. The device supports programmable sensitivity with automatic recalibration for each sensor channel. It offers multiple power states, including a Deep Sleep mode that draws 3uA of quiescent current. The component is housed in a 10-pin DFN package measuring 3mm x 3mm.
Feature Summary
- Five individual capacitive touch sensor inputs with programmable sensitivity
- Full-duplex SPI communication interface
- Automatic environmental recalibration for stable operation
- Low power operation with 3uA quiescent current in Deep Sleep mode
Applications
- Desktop and Notebook PCs
- LCD Monitors
- Printers
- Appliances
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm interface compatibility. Ensure the design accommodates the 10-pin DFN package dimensions. Confirm RoHS compliance status through manufacturer datasheets prior to integration. Validate supply chain authenticity through authorized distribution channels.
Selection Notes
Select this component when a five-channel solution with SPI connectivity is required. Compare against the CAP1006 series if six channels or alternative interfaces like SMBus are needed. Evaluate power consumption requirements against the available standby and deep sleep modes. Consider the 3mm x 3mm footprint constraints during PCB layout planning.
Part Context
This part belongs to the CAP1005/CAP1006 family of capacitive touch sensors originally developed by SMSC before its acquisition by Microchip Technology. The family provides flexible sensing algorithms for various consumer electronics applications. The CAP1005 variant specifically targets designs requiring five independent touch inputs.
Replacement Considerations
Direct substitutes include other parts within the CAP1005/CAP1006 family such as the CAP1006-1-AIA-TR or CAP1006-2-AIA-TR, depending on channel count and interface requirements. Verify pinout compatibility and software register mapping before substitution.
