CYAT81682-100AS61ZT

Touch Screen Controllers Overview

The CYAT81682-100AS61ZT is a capacitive touchscreen controller from Infineon Technologies, part of the TrueTouch Standard TS4200 family. It integrates an Arm Cortex-M0 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 typical operating current of 20 mA. It features a 32-bit resolution and includes four ADC inputs for sensor signal processing. Designed for surface-mount applications, it is housed in a TQFP-100 package and functions reliably across an extended industrial temperature range from -40°C to +105°C.

Touch Screen Controllers Procurement Notes

Verify the specific suffix 'ZT' against official documentation to confirm reel packaging and RoHS compliance status. Confirm the maximum operating temperature rating associated with this specific variant, as suffixes often denote environmental or packaging differences within the same functional family.

Touch Screen Controllers Selection Notes

Select this component when a high-performance MCU-integrated touch controller is required for designs needing flexible bus connectivity via I2C or SPI. Ensure the design accommodates the TQFP-100 footprint and meets the thermal requirements for operation up to +105°C if utilizing the AS grade specifications.

Touch Screen Controllers Part Context

This part belongs to the CYAT81682 series, which utilizes the TrueTouch technology platform. The series is characterized by its integration of processing capabilities directly within the touch controller, reducing system complexity compared to separate MCU and touch controller solutions.

Touch Screen Controllers Replacement Considerations

Check for CYAT81682-100AS61 (tray package) or CYAT81682-100AA61ZT (commercial temp grade) as potential pin-compatible alternatives depending on required temperature range and packaging preference.
