CYAT61659-56LWS41

Overview

The CYAT61659-56LWS41 is a capacitive slider controller manufactured by Infineon Technologies, belonging to the TrueTouch family. It integrates an ARM Cortex CPU for processing touch inputs. 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 and functions reliably across temperatures from -40 °C to +105 °C. The component 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
• Wide operating temperature range up to +105 °C
• QFN-56 surface mount package

Applications

• Human machine interface (HMI) systems
• Smart sensing applications
• General-purpose control panels requiring capacitive input

Procurement Notes

Verify the exact suffix '41' against official Infineon documentation, as standard listings often reference '41T'. Confirm moisture sensitivity levels and reflow soldering profiles prior to assembly. Ensure compatibility with the specific PCB footprint for the QFN-56 package.

Selection Notes

Select this model for applications requiring high-temperature operation up to 105 °C. The QFN-56 package offers a compact form factor compared to TQFP alternatives. Verify that the host system supports both I2C and SPI protocols if interface flexibility is required.

Part Context

This part belongs to the Infineon TrueTouch series, designed for capacitive touch sensing. It utilizes PSoC-based architecture to handle signal processing internally, reducing the load on the main system processor.
