Overview
The CYAT81650-64AA48T is a capacitive slider controller within the Infineon TrueTouch family, designed for touch interface applications. It features a 32-bit resolution and supports I2C and SPI communication interfaces. The device operates on a supply voltage range of 1.71 V to 5.5 V with a maximum operating current of 20 mA. It is housed in a TQFP-64 package suitable for surface mount technology (SMD/SMT). The component functions reliably within an ambient temperature range of -40°C to +85°C.
Feature Summary
- Capacitive Slider Controller architecture
- I2C and SPI interface support
- 32-bit resolution
- 1.71 V to 5.5 V operating voltage
Applications
- Capacitive touch slider interfaces
- Consumer electronics control panels
- Industrial user interface inputs
Procurement Notes
Verify the specific suffix AA48T against official Infineon documentation to confirm pinout and packaging details. Confirm moisture sensitivity level requirements for storage and reflow soldering profiles. Ensure the ordering quantity aligns with the factory pack size of 1500 units per reel as specified by the manufacturer.
Selection Notes
Select this component when a dedicated capacitive slider solution is required rather than a full touchscreen matrix. Verify that the system power budget accommodates the 20 mA maximum operating current. Ensure the host microcontroller supports either I2C or SPI protocols compatible with the controller's interface specifications.
Part Context
This part belongs to the CYAT8165x series of TrueTouch controllers. It is distinct from general-purpose touchscreen controllers by focusing on slider input detection. The TQFP-64 package provides a compact form factor for integration into space-constrained electronic devices requiring linear touch input.
Replacement Considerations
Consult official Infineon cross-reference documents for verified substitutes within the CYAT8165x or CYAT8168x families. Do not assume pin compatibility with other TrueTouch models without verifying the specific datasheet for the replacement part number.
