To meet increased demand for biometric functions in the automotive industry, Infineon Technologies AG has launched two new automotive-qualified PSoC fingerprint sensor ICs. The CYFP10020A00 and CYFP10020S00 sensors are optimized to work with Infineon’s TRAVEO T2G microcontroller family.

Complying with the AEC-Q100 requirements for the automotive industry, these sensors offer fingerprint identification and authentication capabilities that are suited for in-vehicle personalization and payment authentication, such as charging, parking or other services. They can also be used for authentication and identification applications outside the automotive sector.
Infineon partnered with Precise Biometrics, leveraging its Biomatch algorithm software, to provide the fingerprint identification and authentication solution. Both sensors offer precision capacitive circuitry that enables accurate capture of the ridge and valley patterns of a user’s fingerprint. The sensors detect finger touch-down and lift-off events. The sensors can optionally track the movement of the user’s finger and act as a small trackpad for scrolling and selecting menus. The devices can be customized with different types of coatings and bezels for greater design flexibility.
The sensors feature an 8 × 8 mm sensing area on an 8.9 × 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). The CYFP10020A00 sensor offers an operating temperature range of -40°C to 85°C, while the CYFP10020S00 provides an extended range from -40°C to 105°C.
The CYFP10020A00 and CYFP10020S00 fingerprint sensor ICs are now available, as well as an evaluation kit (KIT-FPG1-T2G-B-E-2M). These devices will be showcased at Infineon’s global technology forum OktoberTech 2024 in Silicon Valley, October 17.
