CYAT81652-64AS48

Overview

The CYAT81652-64AS48 is a capacitive touchscreen controller from Infineon Technologies' TrueTouch PSOC-based automotive Gen6 series. It features an Arm Cortex CPU and supports I2C and SPI interfaces. The device operates within a supply voltage range of 1.71 V to 5.5 V, with a maximum operating current of 20 mA. Designed for automotive environments, it functions reliably between -40°C and +105°C. The component is housed in a TQFP-64 package suitable for surface mount technology.

Feature Summary

• Automotive-grade capacitive touchscreen controller based on PSOC architecture
• Supports I2C and SPI serial communication interfaces
• Operates at supply voltages from 1.71 V to 5.5 V
• Extended temperature range up to +105°C

Applications

• Automotive infotainment systems
• Vehicle instrument clusters
• Center console touch controls

Procurement Notes

Verify the specific suffix 'AS48' against official Infineon documentation to confirm the extended temperature grade (+105°C) and tray packaging format. Ensure compatibility with system power rails (1.71V–5.5V) and interface requirements (I2C/SPI). Confirm moisture sensitivity levels and reflow soldering profiles prior to assembly.

Selection Notes

Select this model for applications requiring high-temperature operation up to 105°C. The TQFP-64 package offers a balance of pin count and board space. Compare with the 'AA' suffix variant if a lower temperature rating (-40°C to +85°C) suffices for the target environment. Verify that the 32-bit resolution and 20 mA current consumption align with system constraints.

Part Context

This part belongs to the CYAT8165x family within the PSoC Automotive Gen6 lineup. It is designed for small to medium-sized touchscreens in vehicles, supporting features like glove touch and wet finger tracking. The series leverages Infineon's established automotive firmware algorithms for robust performance.

Replacement Considerations

Direct substitutes within the same family include CYAT81652-64AA48, which shares the same package and core functionality but has a reduced maximum operating temperature of +85°C instead of +105°C. Verify thermal requirements before swapping.
