Product data sheet
1. General description
The SAF1562HL 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 two transceivers that are compliant with Hi-Speed USB and Original
USB. The functional parts of the SAF1562HL 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 SAF1562HL 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 SAF1562HL provides two downstream ports, allowing
simultaneous connection of USB devices at different speeds.
The SAF1562HL 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 SAF1562HL 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 SAF1562HL is ideally suited for use in Hi-Speed USB mobile applications and
embedded solutions. The SAF1562HL uses a 12 MHz crystal.
