Infineon Technologies has introduced two new automotive-qualified fingerprint sensor ICs, the CYFP10020A00 and CYFP10020S00, designed to enhance biometric authentication in vehicles. Optimized for use with Infineon’s TRAVEO T2G microcontroller family, these sensors comply with AEC-Q100 standards, making them ideal for automotive applications.

With the growing trend of biometric functions in the automotive industry, fingerprint sensing offers accurate and cost-effective biometric performance. Compared to other means of authentication like using a smartphone or typing a pin in a user interface of the vehicle, fingerprint sensing provides less hassle and better ease of use for the driver. The new sensors enable seamless in-vehicle personalization and payment authentication for services such as charging and parking Infineon has partnered with Precise Biometrics for Biomatch algorithm software to provide a best-in-class fingerprint identification and authentication solution.

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).
