Overview
The CYAT81650-64AS48 is a capacitive touchscreen controller from Infineon Technologies, part of the TrueTouch Standard TS3xxx family. It integrates an Arm Cortex-M0 CPU for advanced signal processing and gesture recognition. The device supports I2C and SPI interfaces and operates within a supply voltage range of 1.71 V to 5.5 V. Designed for SMD/SMT installation in TQFP-64 packages, it functions reliably between -40°C and +85°C with a typical operating current of 20 mA.
Feature Summary
- Integrated Arm Cortex-M0 CPU for programmable gesture detection and signal processing
- Supports both I2C and SPI communication interfaces
- Wide supply voltage operation from 1.71 V to 5.5 V
- Capacitive touchscreen control with TrueTouch technology
Applications
- Smartphones and mobile devices
- Tablets and portable media players
- Industrial control panels requiring touch input
Procurement Notes
Verify the specific suffix 'AS48' against official Infineon documentation to confirm temperature grade and packaging details, as datasheets may list variants like 'AA48'. Confirm moisture sensitivity levels and reflow soldering profiles prior to assembly. Check for RoHS compliance status in the latest product release notes.
Selection Notes
Select this component when a dedicated touchscreen controller with embedded processing capabilities is required. Ensure the system design accommodates the 1.71 V to 5.5 V power domain. Verify that the host processor supports either I2C or SPI protocols for data exchange. Consider the TQFP-64 footprint constraints during PCB layout.
Part Context
This part belongs to the Infineon TrueTouch Standard TS3xxx series, which provides high-performance capacitive touch solutions. The CYAT8165x series specifically targets applications needing robust gesture support and low power consumption. It serves as a bridge between the touch sensor panel and the main application processor.
Replacement Considerations
Direct replacements within the same package and pinout include other CYAT8165x variants such as CYAT81650-64AA48, provided the temperature range and interface requirements match. Cross-referencing with Cypress Semiconductor legacy parts may be necessary if migrating from older designs.
