Algorithm-heavy mid-tier performer

AS578

The AS578 is the AS-family chip where the design budget leans on algorithm rather than peripheral breadth — a fingerprint safe SoC tuned for tough rejection-rate targets inside industrial access hardware. It is the mid-tier performer between the module companion parts and the flagship: same engine, sharper cost curve.

High-rejection-rate logic at a mid-tier price.

Industrial gate hardware is where the FAR/FRR budget matters most: a false accept at a logistics yard door is not a rounding error. The AS578 concentrates the silicon spend where it counts — the matching engine — while keeping interfaces lean:

  • Algorithm-first silicon — the DSP engine dominates the die, so rejection targets are met without stepping to flagship-class packaging.
  • One firmware tree — same command dialect as AS608, so a project that later needs more interfaces moves up the family instead of rewriting.
  • Wizard-proof enrollment — SDK routines log FAR/FRR per threshold during commissioning, with thresholds tuned in the field.

Auditable identity at a department's scale.

Announced biometrics programs need identity hardware that survives re-enrollment waves of thousands of people — fingers worn, dried, and never the same twice:

  • BS-array capacitive sensing keeps collection consistent across workers with dissimilar skin conditions (config on request).
  • Unit-level test pass and 24h-class aging flows in the same footprint as the module lines.
  • 2-year warranty from the first unit — a department's refresh cycle, not a race.

AS578 FAQs

One pc is the MOQ. Samples ship in 1–3 days with the free SDK, datasheet and reference schematic for the BS-series pairing.

Its die allocation prioritizes the DSP matching engine over peripheral breadth — you get flagship-class FAR/FRR performance with a leaner interface set and BOM cost point.

Yes — the SDK exposes FAR/FRR thresholds per platform, and the FAE team will help you calibrate against your enrollment population within 48h.
