Fs7605 Touch Fingerprint Sensor With Pureprint-tm- Top: Synaptics

This is a specific request for a technical datasheet or application note for the Synaptics FS7605 (often referred to as the ClearPad FS7605 or simply FS7605), which includes the PurePrint™ anti-spoofing technology and a Touch + Fingerprint sensor.

• Authentication Time: < 150ms (from finger touch to system unlock).
• False Acceptance Rate (FAR): 1 in 100,000 (with PurePrint enabled).
• False Rejection Rate (FRR): < 2% (including wet, dry, or slightly scarred fingers).

3. PurePrint™ Technology – Detailed Analysis

3.1 Principle of Operation

PurePrint™ is an on-sensor neural classification engine that analyzes both spatial and temporal (multi-frame) features of a finger press. Unlike software-based liveness detection, PurePrint™ operates entirely within the FS7605’s firmware ROM, never exposing raw fake fingerprint images to the host CPU. This is a specific request for a technical

The Synaptics FS7605 is a high-performance touch fingerprint sensor designed for professional-grade laptops and mobile workstations, such as the HP EliteBook 800 series and ZBook lineups. It is part of the Natural ID™ platform, which focuses on combining speed with enterprise-level security. Core Technology: PurePrint™ Authentication Time: &lt; 150ms (from finger touch to
