ISP1582
Hi-Speed USB peripheral controller
Rev. 09 — 29 September 2009
Product data sheet
1. General description
The ISP1582 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 ISP1582 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 ISP1582 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 internal generic Direct Memory Access (DMA) block allows easy integration into data
streaming 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 ISP1582 also incorporates features such as SoftConnect1, 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.
