Digital Core Design, an IP Core provider and System-on-Chip design house from Poland, has introduced a USB [IP Core] combo pack, which consists of Audio, Human Interface Device and Mass Storage platforms. It’s only up to the project criteria, if either a standalone USB Device Controller or a complete set of USB solutions will be implemented in silicon.

The Universal Serial Bus (USB) connects more than computers and peripherals. Some say, that it has the power to connect the whole new digital world. That’s why, a trusted and safe connection is crucial. – Nowadays it’s hard to imagine a digital device without a USB port – no matter if it’s a standard, mini, micro or even a converter – says Jacek Hanke, CEO of Digital Core Design – And for that reason, we introduced the USB [IP Core] combo pack, which is a complete solution for almost all Universal Serial Bus related designs.

The DUSB2 is a hardware implementation of a full/high-speed peripheral controller, which interfaces to the UTMI bus transceiver. It contains a USB PID and address recognition logic, state machines to handle USB packets and transactions, as well as endpoints number recognition logic and endpoints FIFO control logic. DCD’s solution is designed to support 12 Mb/s “Full Speed” (FS) and 480 Mb/s “High Speed” (HS) serial data transmission rates. Moreover, as the DUSB2 is technology independent, it can be implemented in a variety of process technologies. The core strictly conforms to the USB Specification (v2.0). It is delivered with fully automated test bench and complete set of tests, allowing easy package validation at each stage of SoC design flow.

The USB 2.0 Mass Storage Design Platform is a complete, integrated solution, dedicated for a wide range of USB based Mass Storage Devices. Thanks to a compact code, it can be used in various applications, like portable flash memories, digital audio players, card readers, digital cameras and so on.

The second option, is a universal solution for a Human Interface Device Design Platform. A strict and fully synthesizable code allows implementation in a broad variety of target devices, inter alia keyboards, mice, tablets, steering wheels and gamepads. It can also be used in industrial devices, like e.g. barcode scanners or pen tablets.

And last but not least – the USB Audio Design Platform. With its distinguished marks, like a lite design, small gate count and fast operation, DCD’s solution can be easily implemented in numerous audio projects, but it offers something more than just a standard solution for microphones or speakers.

The DCD’s Mass Storage, Human Interface Device and Audio Design Platforms include:

• DUSB2 peripheral controller, designed to support 12 Mb/s “Full Speed” (FS) and 480 Mb/s “High Speed” (HS) serial data transmission rates
• DP8051XP ultra high performance, speed optimized, fully customizable 8051 8-bit microcontroller, with a built-in DoCD^TM debug IP core
• Audio Devices software stack, optimized for the DP8051XP 8-bit CPU
• FPGA board with ready to use, preprogrammed example USB stereo speakers application
• HAD2 – DoCD^TM Hardware Assisted Debugger board
• DoCD^TM Debug Software
• DoCD^TM driver for Keil development software
• DoCD^TM driver for IAR development software
