CYAT61659-64AA48

Overview

The CYAT61659-64AA48 is a capacitive slider controller manufactured by Infineon Technologies, part of the PSoC-based TrueTouch family. It integrates an ARM Cortex CPU for advanced touch processing within a TQFP-64 surface-mount package. The device supports I2C and SPI interfaces for system communication. It operates on a supply voltage range from 1.71 V to 5.5 V with a typical operating current of 20 mA. The component is rated for commercial temperature ranges, functioning between -40°C and +85°C.

Feature Summary

• Integrated ARM Cortex CPU architecture for programmable touch control
• Supports both I2C and SPI communication protocols
• Wide supply voltage operation from 1.71 V to 5.5 V
• Commercial temperature range specification (-40°C to +85°C)

Applications

• Capacitive slider interfaces in consumer electronics
• Industrial control panels requiring robust touch sensing
• Appliance user interface modules

Procurement Notes

Verify humidity sensitivity classification prior to storage and handling, as the component is moisture-sensitive. Confirm the specific suffix AA48 corresponds to the required commercial temperature grade (+85°C max) rather than the extended industrial variant. Ensure packaging format requirements align with available tray quantities of 1600 units during procurement planning.

Selection Notes

Select this model when a dedicated capacitive slider controller with embedded processing capability is required. The TQFP-64 package offers a balance of pin count and board space. Compare against the CYAT61659-64AS48 if an extended industrial temperature range up to +105°C is necessary for the target application environment.

Part Context

This component belongs to the Infineon TrueTouch series, designed for high-performance capacitive touch applications. It utilizes PSoC technology to combine analog front-end sensing with digital processing. The part number structure indicates a 64-pin variant within the AT61659 family, differentiated by temperature rating and packaging suffixes.

Replacement Considerations

The CYAT61659-64AS48 serves as a direct functional alternative with identical electrical specifications but an extended maximum operating temperature of +105°C. Verify that the higher thermal rating does not conflict with existing design constraints or cost targets.
