Preliminary data
1. General description
The ISP1582 is a cost-optimized and feature-optimized Hi-Speed Universal Serial
Bus (USB) peripheral controller. It fully complies with 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 investments 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 is ideally suited for many types of peripherals, such as: printers,
scanners, 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 ISP1582 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.
