Overview
The CYAT61659-56LWS41T is a capacitive slider controller manufactured by Infineon Technologies, part of the TrueTouch PSOC family. It integrates an ARM Cortex CPU for touch sensing processing. The device supports I2C and SPI interfaces for system communication. It operates within a supply voltage range of 1.71 V to 5.5 V. The component is rated for an extended industrial temperature range from -40 °C to +105 °C. It is housed in a QFN-56 package suitable for surface mount technology.
Feature Summary
- Capacitive slider controller with integrated ARM Cortex CPU
- Dual interface support: I2C and SPI
- Extended operating temperature range up to +105 °C
- QFN-56 surface mount package
Applications
- Industrial human-machine interfaces
- Consumer electronics touch controls
- Appliance slider interfaces
Procurement Notes
Verify RoHS compliance status through official datasheets before integration. Confirm humidity sensitivity handling requirements during storage and assembly. Check current availability status as distribution may be restricted in certain regions. Ensure ordering quantities align with manufacturer reel packaging specifications.
Selection Notes
Select this model when an extended temperature range up to 105 °C is required compared to standard commercial variants. The QFN-56 package offers a compact footprint for space-constrained designs. Verify that the host system supports both I2C and SPI protocols if interface flexibility is needed.
Part Context
This component belongs to the Infineon TrueTouch PSOC series, which combines capacitive touch sensing capabilities with programmable logic. The CYAT61659 series is designed for high-performance touch applications requiring robust signal processing and low power consumption within a single integrated circuit solution.
Replacement Considerations
The CYAT61659-64AA48 is a related variant within the same family but utilizes a TQFP-64 package and has a lower maximum operating temperature of 85 °C. Cross-referencing package dimensions and thermal ratings is essential for direct replacement scenarios.
