Infineon Introduces Automotive-Qualified Fingerprint Sensor IC

By Consultants Review Team Monday, 14 October 2024

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 contact of vehicle, fingerprint sensing provides less inconvenience and better ease of use for the driver. For those reasons, biometric functions are trending in the automotive industry. 

To point out this, Infineon Technologies AG introduces the new automotive-qualified fingerprint sensor ICs CYFP10020A00 and CYFP10020S00. The devices are enhanced for attaching to Infineon’s TRAVEO T2G microcontroller family and comply with the AEC-Q100 gathering for the automotive industry. 

The sensors provide robust fingerprint identification and authentication features, making them perfect for in-vehicle personalization and payment verification for services like charging and parking, as well as for various identification and authentication applications beyond the automotive industry. Infineon has collaborated with Precise 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 degrees Celius, while the CYFp10020S00 supports -40 to +105 degrees Celsius. Both sensors' precision capacitive circuitry enables exact capture of the ridge and valley patterns of a user’s fingerprint. The sensors can detect when a finger touches down and lifts off. 

Additionally, they can optionally track finger movement and include a small trackpad designed for scrolling and menu selection. The devices can be optimized for various types of coatings and bezels. This flexibility allows customers to alter the look and feel of the entire module to best meet their design pals. 

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 encoded with an on-chip AES hardware block and output via an SPI interface to the host-MCU.
