Synaptics Fs7605 Touch Fingerprint Sensor With Pureprint-tm

: PurePrint™ provides encrypted, hardware-based verification to ensure the biometric data is secure and genuine. enterprise IT managers

At the forefront of this revolution sits the . This is not merely a sensor; it is a complete biometric security ecosystem packaged into a silicon wafer thinner than a human hair. For OEMs, enterprise IT managers, and security-conscious consumers, understanding the FS7605 is crucial to understanding the future of authentication.

As Generative AI improves, creating fake biometrics becomes easier. Attackers are no longer just using latent prints; they are generating synthetic fingerprints using GANs (Generative Adversarial Networks) that have never existed on a human hand. and security-conscious consumers

| 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. |

| Parameter | Specification | |-----------|----------------| | | FS7605 | | Technology | Active Capacitive (256 × 256 to 320 × 320 pixels) | | Pixel Pitch | 50 µm (500 dpi) | | Interface | SPI (up to 48 MHz), I²C for configuration | | Package | 6.5 × 6.5 × 1.2 mm LGA (TMR Top variant) | | Operating Voltage | 1.8 V (I/O), 3.3 V (sensor analog) | | Power | 35 µA (sleep), 12 mA (active acquisition) | | ESD Protection | ±15 kV contact (HBM) – integrated TVS | | Operating Temp | -40°C to +85°C |

On‑chip liveness detection eliminates the risk of fake fingerprint attacks at the OS level, while TMR Top reduces bill of materials and mechanical complexity.
