• Includes water rejection, large object rejection, and thin glove support (≤1 mm).
• Integrates a 32-bit Arm Cortex CPU and an internal DSP for data processing.

Touch Screen Controllers Applications

• Automotive in-cell hybrid touchscreen displays.
• Multi-touch interfaces requiring high noise suppression.
• Applications supporting wet finger tracking or thick overlay environments.

Touch Screen Controllers Procurement Notes

Verify the specific ordering suffix against the manufacturer's datasheet to confirm feature sets such as gesture touch support. Confirm the required ambient temperature range, as the 'A' suffix denotes the -40°C to +85°C Automotive-A grade. Ensure compatibility with the intended host system's I2C voltage levels before procurement.

Touch Screen Controllers Selection Notes

Select this component when a 64-channel receiver configuration is required for displays up to 20 inches diagonal. Choose the Automotive-A variant for standard cabin applications operating between -40°C and +85°C. Verify that the system design accommodates the specified 3.0 V to 5.5 V analog supply requirements.

Touch Screen Controllers Part Context

This part belongs to the Infineon PSoC Automotive Multitouch Generation 7XL series. It is specifically engineered for hybrid in-cell sensor configurations where TX/VCOM share a layer and the RX ITO layer is positioned on or above the color filter.

Touch Screen Controllers Replacement Considerations

The CYAT827AZS64-2200A serves as a functional alternative within the same generation, offering identical channel counts and core specifications while differing in package handling characteristics.
