1. General description
The ISP1583 is a cost-optimized and feature-optimized Hi-Speed Universal Serial
Bus (USB) peripheral controller. It fully complies with Universal Serial Bus
Speciï¬cation Rev. 2.0, supporting data transfer at high-speed (480 Mbit/s) and
full-speed (12 Mbit/s).
The ISP1583 provides high-speed USB communication capacity to systems based
on microcontrollers or microprocessors. It communicates with a microcontroller or
microprocessor of a system through a high-speed general-purpose parallel interface.
The ISP1583 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 ï¬t into
all existing device classes, such as imaging class, mass storage devices,
communication devices, printing devices and human interface devices.
The ISP1583 is a low-voltage device, which supports I/O pad voltages from 1.65 V to
3.6 V.
The internal generic Direct Memory Access (DMA) block allows easy integration into
data streaming applications. In addition, the various conï¬gurations of the DMA block
are tailored for mass storage 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 ï¬rmware investments shortens the
development time, eliminates risk and reduces cost. The result is fast and efï¬cient
development of the most cost-effective USB peripheral solution.
The ISP1583 is ideally suited for many types of peripherals, such as: printers;
scanners; magneto-optical, compact disc, digital video disc and Zip® 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 ACPIâ¢, OnNow⢠and USB power management requirements.
The ISP1583 also incorporates features such as SoftConnectâ¢, a reduced
frequency crystal oscillator, and integrated termination resistors. These features allow
signiï¬cant cost savings in system design and easy implementation of advanced USB
functionality into PC peripherals.
