The ISP1563 is a PCI‑based, single‑chip USB host controller that integrates two Original USB OHCI cores, one Hi‑Speed USB EHCI core and four compliant transceivers. It supports high‑speed (480 Mbit/s), full‑speed (12 Mbit/s) and low‑speed (1.5 Mbit/s) USB transfer modes and provides four downstream ports with green and amber LED status indicators.
Key features include a 32‑bit, 33 MHz PCI interface, 3.3 V I/O pins, hot‑plug and remote‑wake support, individual port over‑current protection, and operation over a full‑industrial temperature range (‑40 °C to +85 °C). The device is intended for use in motherboards, PCI add‑on cards, notebooks, set‑top boxes and other embedded solutions.
