Touch Screen Controllers Procurement Notes

Verify that the specific ordering suffix matches the required feature set, as variations exist within the CYAT817X series regarding secondary communication interfaces and sensor support. Confirm package availability in 128LD TQFP format. Ensure compliance with automotive environmental standards for the specified temperature range during procurement planning.

Touch Screen Controllers Selection Notes

Select this model for applications requiring 77 sense pins and ten-finger multitouch without force touch or slider capabilities. Compare against variants like CYAT817AZS77-5BFBA if additional features such as haptic feedback or CAN interface are needed. Ensure the host system supports I2C or SPI communication protocols compatible with the device's slave interface requirements.

Touch Screen Controllers Part Context

This component belongs to the Infineon PSoC™ Automotive Multitouch generation 7XL family. It is designed specifically for automotive human-machine interface (HMI) applications. The part number indicates a 77-sense-pin configuration with an Automotive-A temperature rating (-40°C to 85°C) and a TQFP package.

Touch Screen Controllers Replacement Considerations

Direct replacements within the same family include CYAT817AZS77-5BFBA or CYAT817AZS77-5A202, depending on whether additional features like haptics or sliders are required. Verify pin compatibility and firmware support when substituting.
