ISP1582BS

Product Summary

The ISP1582BS is a cost-optimized and feature-optimized Hi-Speed Universal Serial Bus (USB) peripheral controller. It fully complies with Ref. 1 "Universal Serial Bus Specification Rev. 2.0", supporting data transfer at high-speed (480 Mbit/s) and full-speed (12 Mbit/s). The ISP1582BS provides high-speed USB communication capacity to systems based on microcontrollers or microprocessors. It communicates with a microcontroller or microprocessor of a system through a high-speed general-purpose parallel interface. The applications of the ISP1582BS are Personal digital assistant, Digital video camera, Digital still camera, 3G mobile phone, MP3 player, Communication device, for example: router and modem, Printer and Scanner.
