Product data sheet
1. General description
The ISP1563 is a Peripheral Component Interconnect (PCI)-based, single-chip Universal
Serial Bus (USB) Host Controller. It integrates two Original USB Open Host Controller
Interface (OHCI) cores, one Hi-Speed USB Enhanced Host Controller Interface (EHCI)
core, and four transceivers that are compliant with Hi-Speed USB and Original USB. The
functional parts of the ISP1563 are fully compliant with Universal Serial Bus Specification
Rev. 2.0, Open Host Controller Interface Specification for USB Rev. 1.0a, Enhanced Host
Controller Interface Specification for Universal Serial Bus Rev. 1.0, PCI Local Bus
Specification Rev. 2.2, and PCI Bus Power Management Interface Specification Rev. 1.1.
The integrated high performance USB transceivers allow the ISP1563 to handle all
Hi-Speed USB transfer speed modes: high-speed (480 Mbit/s), full-speed (12 Mbit/s) and
low-speed (1.5 Mbit/s). The ISP1563 provides four downstream ports, allowing
simultaneous connection of USB devices at different speeds.
The ISP1563 provides downstream port status indicators, green and amber LEDs, to
allow user-rich messages of the Root Hub downstream ports status, without requiring
detailed port information in the internal registers.
The ISP1563 is fully compatible with various operating system drivers, such as Microsoft
Windows standard OHCI and EHCI drivers that are present in Windows XP,
Windows 2000 and Red Hat Linux.
The ISP1563 directly interfaces to any 32-bit, 33 MHz PCI bus. Its PCI pins can source
3.3 V. The PCI interface fully complies with PCI Local Bus Specification Rev. 2.2.
The ISP1563 is ideally suited for use in Hi-Speed USB host-enabled motherboards,
Hi-Speed USB host PCI add-on card applications, mobile applications, and embedded
solutions.
To facilitate motherboard development, the ISP1563 can use the available 48 MHz clock
signal to reduce the total cost of a solution. To reduce Electro-Magnetic Interference
(EMI), however, it is recommended that the 12 MHz crystal is used in PCI add-on card
designs.
