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

: Unlike traditional "match-on-host" sensors that send sensitive data to the laptop's main CPU, the FS7605 is a fully hardware-encapsulated solution. It performs all matching and authentication on a single, isolated System-on-Chip (SoC) to prevent malware from intercepting biometric templates.

Unlike traditional sensors that simply read the 2D surface of a finger, the

: For adaptive fingerprint template matching. Test conditions: ARM Cortex-M4 @ 64 MHz, 256

Test conditions: ARM Cortex-M4 @ 64 MHz, 256 KB SRAM, dry finger, room temperature.

Compatible with Windows 7, 8, 8.1, 10, and 11 (64-bit and 32-bit), making it highly versatile for corporate IT environments. and ease of integration

Warehouse scanners and medical tablets require gloves-off security. The FS7605's ability to read low-amplitude fingerprints (common in manual laborers with worn ridges) makes it superior to optical sensors.

| Feature | Benefit | |---------|---------| | | Swipe down (notifications), double‑tap (wake), long‑press (action) directly from sensor area without separate touch IC. | | Reduced Z‑height | Total module height ≤ 1.2 mm (40% thinner than sensor + separate touch button). | | Water rejection | TMR layer provides baseline touch detection even when sensor surface is wet; fingerprint capture degraded but wake/gesture still works. | | Wake‑on‑touch | Sensor enters µA mode and uses TMR layer to detect approach/wake, avoiding need for proximity sensor. | self-contained fingerprint authentication.

| Level | FAR (fake) | FRR (live) | Use case | |-------|------------|------------|----------| | Low | 0.1% | 1% | Convenience (unlock device) | | Medium (default) | 0.01% | 2% | Payments, app login | | High | 0.001% | 5% | High‑security (corporate, medical) |

The Synaptics FS7605 with PurePrint™ technology sets a benchmark for secure, self-contained fingerprint authentication. By integrating liveness detection and match-in-sensor architecture, it eliminates the two most common attack vectors – spoofing and image interception. With low power, fast response, and ease of integration, the FS7605 is an optimal choice for designers requiring biometric security in consumer and industrial products.
