Interface card adapter ACTIS ACM39U-Y3 — USB 1.1, ISO 7816 T=0/T=1, Memory card support, 82×70×10 mm, Black/Green

The ACM39U-Y3 is a module-style smart card interface based on the ACR39 core, designed to provide secure access control for embedded systems and card-based solutions. It supports memory and microprocessor smart cards with T=0 and T=1 protocols and complies with ISO 7816 Class A, B and C. The module connects via USB Full Speed and is built for long service life with a minimum endurance of 100,000 card insertion cycles.

Advantages

The ACM39U-Y3 combines the proven ACR39 core with modern microchip technology to deliver high security for confidential data while remaining compact and easy to integrate. It offers USB Full Speed connectivity, a smart card read/write throughput of up to 600 Kbps, and wide protocol compatibility (T=0, T=1, memory cards). Compliance with PC/SC and CCID standards ensures driver compatibility across major operating systems including Windows, Linux, macOS and Android (3.1+).
