SmartDV’s USB 2.x Device IP is a silicon-proven, fully featured Universal Serial Bus device solution purpose-built for SoC designs requiring reliable, high-speed USB device connectivity across embedded, automotive, IoT, and consumer electronics applications. Fully compliant with USB 2.0, it delivers complete device-side USB functionality supporting High Speed (480 Mbps), Full Speed (12 Mbps), and Low Speed (1.5 Mbps) operation via UTMI transceivers in both 8-bit and 16-bit modes, with 16 bidirectional endpoints and integrated DMA controller functions — providing a proven, production-ready USB device interface for the most demanding embedded SoC designs.
Designed to address the full breadth of USB 2.x device integration requirements, the IP supports Interrupt, Bulk, Isochronous, and Control transfers including High Bandwidth Interrupt and Isochronous endpoints, three caching models for optimized memory access, descriptor and data pre-fetch and pre-compute, NAK counter for unnecessary memory access limiting, and Low Power Management with fsls serial mode. Its comprehensive error handling, USB Suspend with remote wakeup, clock gating with multi-power-well support, and system low power state management give SoC teams a production-tested, feature-complete USB 2.x device implementation optimized for power-sensitive embedded applications.
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 UTMI 8-bit and 16-bit interface support and clean host interface enable fast integration and confident design bring-up across a wide range of process nodes and target applications.
