The CAP1006-1-AIA-TR is a six-channel capacitive touch sensor manufactured by Microchip Technology. It features an SMBus/I2C compliant interface for communication and operates within a voltage range of 2.7V to 3.6V. The device supports programmable sensitivity with automatic recalibration to compensate for environmental changes. It offers multiple power states, including Deep Sleep mode with a quiescent current of 3µA. The component is housed in a 10-pin DFN package measuring 3mm x 3mm.
Verify the specific suffix AIA-TR confirms the 10-pin DFN 3mm x 3mm RoHS-compliant packaging and SMBus interface variant. Confirm that the ordering code matches the official SMSC/Microchip datasheet documentation for the CAP1006-1 series before finalizing procurement specifications.
Select this component when a six-channel capacitive touch solution with I2C connectivity is required. Ensure the design accommodates the 2.7V to 3.6V supply range and the 3mm x 3mm footprint constraints. Verify compatibility with the host controller's I2C bus speed and voltage levels.
This part belongs to the CAP1005/CAP1006 family of capacitive touch sensors originally developed by SMSC and acquired by Microchip Technology. The CAP1006 variant specifically provides six sensing channels compared to the five-channel CAP1005. The -1 suffix denotes the SMBus interface version.
Public confirmed substitute part numbers are not available in the provided documentation. Evaluate the CAP1006-2-AIA-TR only if BC-Link interface compatibility is acceptable instead of SMBus.
