Overview
The CYAT81650-100AS48T is a capacitive touchscreen controller from Infineon's TrueTouch series, built on PSoC architecture. 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. It is housed in a TQFP-100 package suitable for SMD/SMT installation. The component functions across a temperature range of -40°C to +105°C and includes humidity sensitivity considerations.
Feature Summary
- Capacitive Touchscreen Controller with ARM Cortex CPU
- Dual Interface Support: I2C and SPI
- Wide Supply Voltage Range: 1.71 V to 5.5 V
- Extended Operating Temperature: -40°C to +105°C
Applications
- Capacitive touch interface systems
- Industrial control panels requiring wide temperature operation
- Automotive infotainment displays
Procurement Notes
Verify the suffix 'T' against official datasheets, as standard listings for this model often indicate Tray packaging (e.g., 900 units), while 'T' typically denotes Reel packaging. Confirm moisture sensitivity level (MSL) requirements for surface mount assembly processes. Ensure compatibility with the host system's I2C or SPI protocol configuration before procurement.
Selection Notes
Select this model for applications requiring high-temperature stability up to 105°C and robust capacitive sensing via the TrueTouch platform. The TQFP-100 package offers ample pin count for complex electrode configurations. Verify that the host processor supports the required I2C or SPI communication speeds and that the power supply rails align with the 1.71 V to 5.5 V input range.
Part Context
This component belongs to the CYAT8165x family of TrueTouch controllers. It integrates programmable analog and digital blocks typical of PSoC devices, allowing for flexible sensor tuning. The part is distinct from slider-only variants by its designation as a general capacitive touchscreen controller, supporting multi-touch or large-area sensing applications.
Replacement Considerations
Direct substitutes within the same family include CYAT81650-100AA48T (different packaging/temperature grade) or CYAT81652-100AA48T. Cross-family replacement requires verifying pinout compatibility and software driver support for the new controller.
