SmartDV’s USIM Master IP is a silicon-proven, fully featured Universal Subscriber Identity Module interface solution purpose-built for SoC designs requiring reliable, standards-compliant smart card communication across mobile, IoT, automotive, and embedded applications. Fully compliant with ISO/IEC 7816-3 and ETSI TS 102 221 Release 18, it delivers complete USIM master 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 handling — providing a proven, production-ready USIM interface for the most demanding mobile and embedded SoC designs.
Designed for the practical integration requirements of modern mobile and IoT SoC designs, the IP supports adjustable clock and baud rates, configurable automatic byte repetition, Character Waiting Time and Block Waiting Time management, and complete smart card session handling. Its T=0 asynchronous half-duplex character transmission and T=1 asynchronous half-duplex block transmission support give SoC teams a production-tested, spec-complete USIM master implementation that integrates cleanly with the widest range of UICC and smart card devices 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.
