ISP1181B

ISP1181B Full-speed Universal Serial Bus peripheral controller Rev. 02 — 07 December 2004 Product data 1. General description The ISP1181B is a Universal Serial Bus (USB) peripheral controller that complies with Universal Serial Bus Specification Rev. 2.0, supporting data transfer at full-speed (12 Mbit/s). 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 peripheral controller allows the designer to select the optimum system microcontroller from the wide variety available. The ability to reuse existing architecture and firmware investments shortens development time, eliminates risks and reduces costs. The result is fast and efficient development of the...
