1. Introduction
AN10039_4
Application note
The ISP1582/83 is a Hi-Speed Universal Serial Bus (USB) Peripheral Controller that
provides a flexible interface for a wide range of microcontrollers. The high-speed
microcontroller interface increases system throughput and reduces processor utilization.
The ISP1582/83 can be configured to function, with a common USB bus enumeration
process, as a Generic Direct Memory Access (GDMA) application or a mass storage
application.
