topGeneral description
The ISP1581 is a cost-optimized and feature-optimized Hi-Speed Universal Serial Bus (USB) interface device, which fully complies with the
Universal Serial Bus Specification Rev. 2.0. It provides high-speed USB communication capacity to systems based on a microcontroller or
microprocessor. The ISP1581 communicates with the system’s microcontroller/processor through a high-speed general-purpose parallel interface.
The ISP1581 supports automatic detection of Hi-Speed USB system operation. The Original USB fall-back mode allows the device to remain
operational under full-speed conditions. It is designed as a generic USB interface device so that it can fit into all existing device classes, such as:
Imaging Class, Mass Storage Devices, Communication Devices, Printing Devices and Human Interface Devices.
The internal generic DMA block allows easy integration into data streaming applications. In addition, the various configurations of the DMA
block are tailored for mass storage applications.
The modular approach to implementing a USB interface device allows the designer to select the optimum system microcontroller from the wide
variety available. The ability to re-use existing architecture and firmware investments shortens the development time, eliminates risk and reduces
costs. The result is fast and efficient development of the most cost-effective USB peripheral solution.
The ISP1581 is ideally suited for many types of peripherals, such as: printers; scanners; magneto-optical (MO), compact disc (CD), digital video
disc (DVD) and Zip /Jaz drives; 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 compliant to the ACPItm, OnNowtm and USB power management requirements.
The ISP1581 also incorporates features such as SoftConnecttm, a reduced frequency crystal oscillator and integrated termination resistors. These
