Overview
The Infineon CYAT81652-64AA48T is a capacitive slider controller within the TrueTouch family, designed for embedded touch sensing applications. It integrates an Arm Cortex CPU to manage signal processing and gesture detection. The device supports I2C and SPI interfaces for host communication. It operates on a supply voltage range of 1.71 V to 5.5 V with a maximum operating current of 20 mA. The component is rated for industrial temperatures from -40°C to +85°C and is housed in a TQFP-64 surface-mount package.
Feature Summary
- Integrated Arm Cortex CPU for advanced signal processing and gesture recognition
- Supports both I2C and SPI communication protocols
- Wide supply voltage compatibility (1.71 V to 5.5 V)
- Capacitive slider control functionality
Applications
- Industrial control panels requiring linear touch input
- Consumer electronics with slider-based interfaces
- Automotive infotainment systems with capacitive sliders
Procurement Notes
Verify RoHS compliance status through official manufacturer documentation before procurement. Confirm moisture sensitivity level handling requirements during storage and assembly. Ensure ordering quantities align with factory packaging specifications, which may require minimum order multiples based on reel configurations.
Selection Notes
Select this model when a dedicated capacitive slider solution is required rather than a full touchscreen controller. Verify that the TQFP-64 package fits the PCB footprint constraints. Ensure the host system supports either I2C or SPI interfaces as specified by the pin configuration.
Part Context
This part belongs to the CYAT8165x series of TrueTouch controllers. It shares core architecture with other variants like the CYAT81658 but differs in package type (TQFP-64 vs TQFP-100) and specific feature set optimized for slider applications. The 'T' suffix typically indicates tape-and-reel packaging.
Replacement Considerations
Direct replacements within the same series include CYAT81652-64AA48 (tray packaging). Cross-series migration requires careful review of pinout compatibility and firmware differences between TrueTouch generations.
