Based on the component name you provided, you are referring to a specific fingerprint sensor model often found in modern laptops (such as the Dell XPS 13, Lenovo ThinkPad, or HP EliteBook series) and external authentication devices.

4.3 Performance Metrics (TMR Mode)

• Touch report rate – 120 Hz
• Fingerprint acquisition – Concurrently disabled during active touch (to avoid interference), re‑enabled after 50 ms of finger stillness.
• Mutual capacitance SNR – 30 dB (dry finger, 0.5 mm glass cover).

The Synaptics FS7605 Touch Fingerprint Sensor is a flagship biometric security solution designed for high-performance enterprise laptops, such as the HP EliteBook and ProBook series. Based on the component name you provided, you

1. Pixel array – Metal-over-capacitive with TMR Top dielectric stack.
2. Analog front-end (AFE) – Correlated double sampling, gain stage.
3. Digital signal processor – Includes hardware accelerator for PurePrint™.
4. Secure zone – Stores fingerprint templates and liveness thresholds.

SecureLink™ Encryption: Communications between the sensor and the rest of the system are encrypted using TLS 1.2 with 256-bit AES, preventing "man-in-the-middle" attacks. Touch report rate – 120 Hz Fingerprint acquisition

2.1 Sensor Architecture

The FS7605 consists of four main blocks: The Synaptics FS7605 Touch Fingerprint Sensor is a

: This proprietary feature uses artificial intelligence to distinguish between live human fingers and spoofed materials (like silicone or high-resolution images), significantly enhancing security against unauthorized access. Match-in-Sensor™ Architecture
