CYAT81658-64AA48T

Overview

The CYAT81658-64AA48T is a capacitive slider controller from Infineon Technologies, part of the TrueTouch Standard TS3xxx family. It integrates an ARM Cortex-M0 CPU for advanced signal processing and gesture recognition. The device supports I2C and SPI interfaces with a 32-bit resolution. It operates within a supply voltage range of 1.71 V to 5.5 V and functions between -40°C and +85°C. Housed in a TQFP-64 package, it is designed for high-performance touch applications requiring precise linear input detection.

Feature Summary

• Integrated ARM Cortex-M0 processor for custom gesture algorithms
• Supports both I2C and SPI communication protocols
• Capacitive sensing technology with 32-bit resolution
• Wide operating temperature range from -40°C to +85°C

Applications

• Linear touch sliders in consumer electronics
• Volume or brightness control interfaces
• Industrial control panels requiring linear input
• Automotive infotainment systems

Procurement Notes

Verify the specific suffix AA48T confirms the tape-and-reel packaging format intended for automated surface-mount assembly. Confirm RoHS compliance status through official documentation prior to integration. Ensure design compatibility with the required I2C or SPI bus speeds supported by the host microcontroller.

Selection Notes

Select this component when a dedicated capacitive slider solution is required rather than a full matrix touchscreen. The TQFP-64 package offers a balance of pin count and board space. Verify that the application environment stays within the specified -40°C to +85°C operational temperature limits for reliable performance.

Part Context

This part belongs to the CYAT8165x series, which utilizes PSoC technology to combine analog touch sensing blocks with digital processing cores. The 'T' suffix typically denotes reel packaging, distinguishing it from tray-packaged variants like the CYAT81658-64AS48.

Replacement Considerations

Direct substitutes within the same family include CYAT81658-64AA48 (tray) or CYAT81658-64AS48T. Cross-family replacements require verification of pinout compatibility and firmware adaptation due to differences in sensor channel counts and interface configurations.
