Touch Screen Controllers Procurement Notes

Verify the specific ordering suffix against the official Infineon datasheet to confirm feature sets such as CAN interface or crypto engine availability. Ensure the selected package matches the required PCB footprint, as this model utilizes a 128LD TQFP configuration.

Touch Screen Controllers Selection Notes

Select this component when designing for automotive environments requiring AEC-Q100 compliance. The 72-sense pin count suits medium-sized displays. Confirm that the host system supports the required I²C or SPI bit rates for data transfer.

Touch Screen Controllers Part Context

This part belongs to the CYAT817X series, which includes variants with different sense pin counts (61, 72, 77, 88, 98) and temperature grades. The 'S' suffix indicates the –40°C to 105°C range, while 'A' denotes –40°C to 85°C.

Touch Screen Controllers Replacement Considerations

Direct substitutes include other CYAT817AZS72 variants like CYAT817AZS72-3BFBA if additional features are needed. Verify pin compatibility and firmware support before swapping.
