October 14, 2024 /SemiMedia/ — Infineon Technologies AG launches new automotive-qualified fingerprint sensor ICs CYFP10020A00 and CYFP10020S00 to address the growing trend of biometric functions in the automotive industry. These devices are optimized for integration with Infineon's TRAVEO™ T2G microcontroller family and meet AEC-Q100 standards.

Fingerprint sensing offers accurate and cost-effective biometric performance, providing a more convenient alternative to traditional authentication methods, such as using a smartphone or entering a PIN on a vehicle's interface. The new sensors deliver robust fingerprint identification and authentication capabilities, making them ideal for in-vehicle personalization and payment authentication, including charging, parking, and other services. They are also suitable for applications beyond the automotive sector.

The CYFP10020A00 sensor supports an operating temperature range of -40 to +85 °C, while the CYFP10020S00 supports -40 to +105 °C. Both sensors' precision capacitive circuitry enables accurate capture of the ridge and valley patterns of a user's fingerprint. The sensors detect finger touch-down and lift-off events. Optionally, the sensor can track the movement of the user's finger and act as a small trackpad suitable for scrolling and selecting menus. The devices can be optimized for different types of coatings and bezels. This flexibility allows customers to customize the look and feel of the entire module to best meet their design goals. The sensors feature an 8 x 8 mm sensing area on an 8.9 x 9.3 mm BGA package, and support power supply options ranging from 1.8 to 5.5 V. The fingerprint data is encrypted with an on-chip AES hardware block and output via an SPI interface to the host-MCU (e.g. TRAVEO T2G microcontroller).

Infineon has partnered with Precise Biometrics to integrate the Biomatch algorithm software, ensuring a best-in-class fingerprint identification and authentication solution.

The new automotive-qualified fingerprint sensor ICs CYFP10020A00 and CYFP10020S00 are now available, as well as an evaluation kit (KIT-FPG1-T2G-B-E-2M). For more information, please visit www.infineon.com/psocfpg1.
