CYAT61659-64AS48

Overview

The CYAT61659-64AS48 is a capacitive slider controller manufactured by Infineon Technologies, part of the PSoC-based TrueTouch family. It integrates an Arm Cortex CPU for advanced signal processing and touch sensing capabilities. 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 draws a working power current of 20 mA. The component is rated for an extended industrial temperature range from -40°C to +105°C. It is housed in a TQFP-64 surface-mount package.

Feature Summary

• Integrated Arm Cortex CPU for programmable touch control
• Supports both I2C and SPI communication interfaces
• Capacitive slider controller functionality
• Extended operating temperature range up to +105°C

Applications

• Capacitive touch slider interfaces
• Industrial control panels requiring wide temperature tolerance
• Consumer electronics with programmable touch gestures

Procurement Notes

Verify moisture sensitivity levels before handling, as the component is classified as sensitive. Confirm the specific suffix 'S48' corresponds to the required industrial temperature grade (+105°C) rather than commercial grades. Ensure compatibility with the TQFP-64 footprint during PCB layout. Check for RoHS compliance status through official manufacturer documentation prior to integration.

Selection Notes

Select this model when a dedicated capacitive slider controller with embedded processing is required. The choice between AS48 (industrial) and AA48 (commercial) depends on the operational environment's maximum temperature. Verify that the host system can support the necessary I2C or SPI protocols. Consider the 20 mA current consumption against available power budgets.

Part Context

This component belongs to the Infineon TrueTouch series, which combines capacitive sensing technology with programmable processors. The CYAT61659 variant specifically targets slider applications, offering flexibility through its CPU architecture compared to fixed-function controllers. It serves as an upgrade path for designs requiring enhanced gesture recognition or custom touch mapping.

Replacement Considerations

The CYAT61659-64AA48 is a pin-compatible alternative with a lower commercial temperature rating (-40°C to +85°C). Direct substitution requires confirming that the application does not exceed 85°C. Other variants in the CYAT616xx family may differ in pin count or interface options.
