CYAT81658-64AA48

Overview

The CYAT81658-64AA48 is a capacitive slider controller from Infineon Technologies, part of the TrueTouch family. It operates within a supply voltage range of 1.71 V to 5.5 V and supports I2C and SPI interfaces. The device features a 32-bit resolution and functions reliably between -40°C and +85°C. Packaged in a TQFP-64 surface-mount format, it is designed for precise linear touch sensing applications requiring robust signal processing capabilities.

Feature Summary

Capacitive Slider Controller with 32-bit resolution
Dual interface support: I2C and SPI
Operating temperature range: -40°C to +85°C
Supply voltage range: 1.71 V to 5.5 V

Applications

Linear touch control interfaces
Slider-based user input devices
Industrial control panels

Procurement Notes

Verify the specific suffix '48' against official Infineon documentation to confirm package type and tape/reel specifications. Ensure compatibility with system voltage levels (1.71V–5.5V) and interface protocols (I2C/SPI). Check humidity sensitivity handling requirements during assembly due to moisture sensitivity classification.

Selection Notes

Select this component when a dedicated capacitive slider solution is required rather than a full touchscreen matrix. Confirm that the TQFP-64 package fits the PCB layout constraints. Verify that the operating temperature range of -40°C to +85°C meets the environmental conditions of the target application.

Part Context

This part belongs to the CYAT8165x series of TrueTouch controllers. It shares core architecture with other variants like CYAT81652 but differs in packaging and specific configuration options defined by the ordering suffix. It is distinct from multitouch screen controllers in its focus on single-axis or linear sensing.

Replacement Considerations

Direct substitutes within the same series include CYAT81658-64AS48, which offers similar electrical characteristics but may differ in packaging (Tray vs. Reel) or temperature grade. Cross-series replacement requires careful verification of pinout compatibility and firmware support.
