ISP1181ADGG

Product Summary

The ISP1181ADGG 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 ISP1181ADGG communicates with the system’s microcontroller or microprocessor through a high-speed general-purpose parallel interface. The applications of the ISP1181ADGG include Personal Digital Assistant (PDA), Digital camera Communication device, for example: Router, Modem, Mass storage device, for example: Zip drive, Printer, Scanner.
