SmartDV’s USIM Slave IP is a silicon-proven, fully featured Universal Subscriber Identity Module device interface solution purpose-built for SoC designs requiring reliable, standards-compliant smart card device-side communication across mobile, IoT, automotive, and embedded security applications. Fully compliant with ISO/IEC 7816-3 and ETSI TS 102 221 Release 18, it delivers complete USIM slave functionality supporting both T=0 and T=1 communication protocols with full smart card session management including card activation, deactivation, cold and warm reset, and ATR response generation — providing a proven, production-ready USIM device interface for the most demanding mobile and embedded SoC designs.
Designed as the natural card-side complement to a USIM master controller, the IP handles the complete slave-side smart card session including ATR generation, APDU command reception, and response data transmission. Its Character Waiting Time, Block Waiting Time, and Block Guard Time support, adjustable clock and baud rates, and configurable automatic byte repetition give SoC and UICC teams a production-tested, spec-complete USIM slave implementation that integrates cleanly with the widest range of USIM master controllers across 2G, 3G, 4G, and 5G mobile platforms.
Built for design flexibility and silicon efficiency, the IP core is highly configurable for both ASIC and FPGA implementations, with a strong focus on area optimization, power management, and peak performance. Its parameterized architecture and clean host interface enable fast integration and confident design bring-up across a wide range of process nodes and target applications.
