Universal Serial Bus 2.0 high-speed interface device

Rev. 02 — 23 October 2000

Objective speciﬁcation

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 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 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 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 ACPI™, OnNow™ and USB power management

requirements.

The ISP1581 also incorporates features such as SoftConnect™, a reduced

frequency crystal oscillator and integrated termination resistors. These features allow

signiﬁcant cost savings in system design and easy implementation of advanced USB

functionality into PC peripherals.
