The ISP1583 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 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.
