CYFP10020S00

Overview

The CYFP10020S00 is an automotive-grade fingerprint sensor IC from Infineon Technologies, designed for secure biometric authentication in vehicle environments. It supports an operating temperature range of -40 to +105 °C, ensuring reliability under extreme conditions. The component integrates sensing capabilities with processing logic, functioning as a complete solution for touch-based fingerprint recognition systems.

Feature Summary

• Automotive-grade qualification for harsh environmental stability
• Integrated capacitive fingerprint sensing and processing
• Extended high-temperature operational capability up to 105 °C

Applications

• Vehicle interior biometric access control
• Driver identification and personalization systems
• Secure infotainment user authentication

Procurement Notes

Verify the specific suffix 'S00' to confirm the extended temperature rating of -40 to +105 °C, distinguishing it from the 'A00' variant which operates up to 85 °C. Confirm automotive grade compliance through official datasheets before integration into safety-critical vehicle subsystems.

Selection Notes

Select this model when high-temperature resilience is required for dashboard or console-mounted applications. Ensure the design accommodates the specific interface requirements of the PSoC-based architecture and validates compatibility with the intended vehicle's power and signal constraints.

Part Context

This sensor belongs to Infineon’s new generation of automotive fingerprint ICs, introduced alongside the CYFP10020A00. It is part of a family aimed at replacing traditional key-based entry methods with secure, touch-based biometric solutions for modern connected vehicles.

Replacement Considerations

The CYFP10020A00 serves as a related variant within the same product family. However, it offers a lower maximum operating temperature of 85 °C compared to the S00’s 105 °C limit. Substitution requires verification that the ambient thermal environment remains within the A00 specifications.
