ISP1181B pdf,datasheet
Universal Serial Bus Specification Rev. 2.0 (full speed). It provides full-speed USB communication capacity to microcontroller or microprocessor-based systems. The ISP1181B communicates with the system’s microcontroller or microprocessor through a high-speed general-purpose parallel interface. The ISP1181B supports fully autonomous, multi-configurable Direct Memory Access (DMA) operation. The modular approach to implementing a USB interface device allows the designer to select the optimum system microcontroller from the wide variety available. The ability to re-use existing architecture and firmware investments shortens development time, eliminates risks and reduces costs. The result is fast and efficient development of the most cost-effective USB peripheral solution. The ISP1181B is ideally suited for application in many personal computer peripherals, such as printers, communication devices, scanners, external mass storage (Zip® drive) devices and digital still cameras. It offers an immediate cost reduction for applications that currently use SCSI implementations.
