1. General description
2. Features
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
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.
