INTEGRATED CIRCUITS PDIUSBD12 USB interface device with parallel bus Product specification Supersedes data of 1998 Sep 24 1999 Jan 08 Philips Semiconductors Philips Semiconductors Product specification USB interface device with parallel bus PDIUSBD12 FEATURES Complies with the Universal Serial Bus specification Rev. 1.1 High performance USB interface device with integrated SIE, FIFO memory, transceiver and voltage regulator DESCRIPTION The PDIUSBD12 is a cost and feature-optimized USB device. It is normally used in microcontroller-based systems and communicates with the system microcontroller over the high speed general-purpose parallel interface. It also supports local DMA transfer. This modular approach to implementing a USB interface allows the designer to choose the optimum system microcontroller from the available wide variety. This flexibility cuts down the development time, risks, and costs by allowing the use of the existing architecture and minimize firmware investments. This results in the fastest way to develop the most cost-effective USB peripheral solution. The PDIUSBD12 fully conforms to the USB specification Rev. 1.1. It is also designed to be compliant with most device class specifications: Imaging Class, Mass Storage Devices, Communication Devices, Printing Devices, and Human Interface Devices. As such, the PDIUSBD12 is ideally suited for many peripherals like Printer, Scanner, External Mass Storage (Zip Drive), Digital Still Camera, etc. It offe...
