  2. 2007/08/30 AT78C5009 -Serial ATA Host Bridge
General description
The ISP1562 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 ISP1562 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.
Integrated high performance USB transceivers allow the ISP1562 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 ISP1562 provides two downstream ports, allowing simultaneous connection of USB devices at different speeds.
The ISP1562 is fully compatible with various Operating System (OS) drivers, such as Microsoft Windows standard OHCI and EHCI drivers that are present in Windows XP, Windows 2000 and Red Hat Linux.
The ISP1562 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 ISP1562 is ideally suited for use in Hi-Speed USB mobile applications and embedded solutions. The ISP1562 uses a 12 MHz crystal.

Overview
The AT78C5009 SATA Controller bridges the conventional Parallel ATA devices with Serial ATA PHY transceivers. It includes a Serial ATA Link layer, a Transport layer, a Command Layer, two 256 x 32 FIFOs and an IDE Host/Target Controller, a Serial ATA Core and an IDE Controller, and is fully compliant with Serial ATA Gen1. The PHY block is connected to the ATA block by a 20-bit transmit and a 20-bit receive data bus.
This host bridge is intended to adapt a Serial ATA Device interface to an Ultra ATA100 Host interface. Ultra DMA is a data transfer protocol used with the READ DMA, WRITE DMA, READ DMA QUEUED, WRITE DMA QUEUED, and PACKET commands.
TAG Bridge, Host
