Fingerprint module functional block diagram
The CYFP10020x00 sensor is encased within a larger fingerprint sensor module, which is often coated with paint, glass, or a similar protective layer. This module is connected to the host processor via a flexible PCB. The sensor’s design allows for compatibility with various coating types and bezels, enabling manufacturers to customize the look and feel of the fingerprint module to align with their design preferences.
Speed and Accuracy: The Keys to Fingerprint Sensor Performance
The CYFP10020x00 boasts an image acquisition time of approximately 160 ms. When paired with qualified matching software, it achieves a false reject rate (FRR) of less than 1.5% and a false accept rate (FAR) of less than one occurrence per 100,000 reads. These metrics are crucial in evaluating the performance of an authentication solution, as they indicate the likelihood of a legitimate user being rejected and an imposter being authenticated.
Fingerprint (FP) sensing has been a standard feature in the mobile device market for years. Infineon predicts that the global automotive fingerprint market will expand at a compound annual growth rate (CAGR) of 36% through 2028. For drivers, fingerprint sensing offers a simpler and more efficient alternative to other authentication methods, making technology like Infineon’s new ICs a potentially valuable option for original equipment manufacturers (OEMs) in the automotive industry.
