ISP1581 Universal Serial Bus 2.0 high-speed interface device Rev. 02 — 23 October 2000 Objective specification 1. General description The ISP1581 is a cost-optimized and feature-optimized Universal Serial Bus (USB) interface device, which fully complies with the Universal Serial Bus Specification Rev. 2.0. It provides high-speed USB communication capacity to systems based on a microcontroller or microprocessor. The ISP1581 communicates with the system’s microcontroller/processor through a high-speed general-purpose parallel interface. The ISP1581 supports automatic detection of USB 2.0 system operation. The USB 1.1 fall-back mode allows the device to remain operational under full-speed conditions.
