ISP1581
Universal Serial Bus 2.0 high-speed interface device
Rev. 02 鈥?23 October 2000
Objective speci鏗乧ation
1. General description
The ISP1581 is a cost-optimized and feature-optimized Universal Serial Bus (USB)
interface device, which fully complies with the
Universal Serial Bus Speci鏗乧ation
Rev. 2.0.
It provides high-speed USB communication capacity to systems based on a
microcontroller or microprocessor. The ISP1581 communicates with the system鈥檚
microcontroller/processor through a high-speed general-purpose parallel interface.
The ISP1581 supports automatic detection of USB 2.0 system operation. The
USB 1.1 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 鏗乼 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 con鏗乬urations 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 鏗乺mware investments shortens the development
time, eliminates risk and reduces costs. The result is fast and ef鏗乧ient 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

drives; digital still cameras; USB-to-Ethernet links; cable and DSL
modems. The low power consumption during 鈥榮uspend鈥?mode allows easy design of
equipment that is compliant to the ACPI鈩? OnNow鈩?and USB power management
requirements.
The ISP1581 also incorporates features such as SoftConnect鈩? a reduced
frequency crystal oscillator and integrated termination resistors. These features allow
signi鏗乧ant cost savings in system design and easy implementation of advanced USB
functionality into PC peripherals.
