Hi-Speed USB peripheral controller

Rev. 07 — 22 September 2008

Product data sheet

1. General description

The ISP1583 is a cost-optimized and feature-optimized Hi-Speed Universal Serial Bus

(USB) peripheral controller. It fully complies with Ref. 1 “Universal Serial Bus Specification

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 fit 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 configurations 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 firmware 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 ISP1583 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.
