ISP1582 Hi-Speed Universal Serial Bus peripheral controller Rev. 03 - 25 August 2004 Preliminary data 1. General description The ISP1582 is a cost-optimized and feature-optimized Hi-Speed Universal Serial Bus (USB) peripheral controller. It fully plies with Universal Serial Bus Specification Rev. 2.0, supporting data transfer at high-speed (480 Mbit/s) and full-speed (12 Mbit/s). The ISP1582 provides high-speed USB munication capacity to systems based on microcontrollers or microprocessors. It municates with a microcontroller or microprocessor of a system through a high-speed general-purpose parallel interface. The ISP1582 supports automatic detection of Hi-Speed USB system operation. Original USB fall-back mode allows the device to remain operational under full-speed conditions. It is designed as a generic USB peripheral controller so that it can fit into all existing device classes, such as imaging class, mass storage devices, munication devices, printing devices and human interface devices. The internal generic Direct Memory Access (DMA) block allows easy integration into data streaming applications. 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 the development time, eliminates risk and reduces cost. The result is fast and efficient development of the most cost-effective USB peripheral solution. The ISP1582 is ideally suited for many types of peripherals, such as: printers, scanners, digital still cameras, USB-to-Ethernet links, cable and DSL modems. The low power consumption during suspend mode allows easy design of equipment that is pliant to the ACPI™, On Now™ and USB power management requirements. The ISP1582 also incorporates Features such as Soft Connect™, a reduced frequency crystal oscillator, and integrated termination resistors. These Features allow...
