ISP1181BDGG

Product Summary

The ISP1181BDGG is an 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 ISP1181BDGG communicates with the system’s microcontroller or microprocessor through a high-speed general-purpose parallel interface. The ISP1181BDGG 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.
