ISP1561
Datasheet
General description
The ISP1561 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 ISP1561 are fully compliant with Ref. 8 "Universal Serial Bus Specification", Ref. 4 "Open Host Controller Interface Specification for USB", Ref. 2 "Enhanced Host Controller Interface Specification for Universal Serial Bus", Ref. 6 "PCI Local Bus Specification", and Ref. 5 "PCI Bus Power Management Interface Specification".
Integrated high performance USB transceivers allow the ISP1561 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 ISP1561 provides four downstream ports, allowing simultaneous connection of USB devices at different speeds.
The ISP1561 provides three downstream port status indicators, GoodLink along with green and amber LEDs, to allow user-rich messages of the root hub downstream ports status, without requiring detailed port information to be reflected in internal registers.
The ISP1561 is fully compatible with various operating system drivers, such as Microsoft Windows standard OHCI and EHCI drivers that are present in Windows 98 Second Edition (SE), Windows Millennium Edition (Me), Windows XP and Windows 2000.
The ISP1561 directly interfaces to any 32-bit, 33 MHz PCI bus. It has 5 V tolerant PCI pins that can source 3.3 V. The PCI interface fully complies with Ref. 6 "PCI Local Bus Specification".
The ISP1561 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 ISP1561 can use the available 48 MHz clock signal to reduce the total cost of a solution. To reduce the ElectroMagnetic Interference (EMI), however, it is recommended that the 12 MHz clock is used in PCI add-on card designs.
Features
- Complies with Ref. 8 "Universal Serial Bus Specification"
- Supports data transfer at high-speed (480 Mbit/s), full-speed (12 Mbit/s) and low-speed (1.5 Mbit/s)
- Two Original USB OHCI cores are compliant with Ref. 4 "Open Host Controller Interface Specification for USB"
- One Hi-Speed USB EHCI core is compliant with Ref. 2 "Enhanced Host Controller Interface Specification for Universal Serial Bus"
- Supports PCI 32-bit, 33 MHz interface compliant with Ref. 6 "PCI Local Bus Specification", with support for D3cold standby and wake-up modes; all I/O pins are 3.3 V standard, but 5 V tolerant
- Compliant with Ref. 5 "PCI Bus Power Management Interface Specification" for all hosts (EHCI and OHCI), and supports all power states: D0, D1, D2, D3hot and D3cold
- Four downstream ports with support for three types of downstream port indicator LEDs: GoodLink, amber and green LEDs
- CLKRUN support for mobile applications, such as internal notebook design
- Configurable subsystem ID and subsystem vendor ID through external EEPROM
- Configurable two or four port root hub
- Digital and analog power separation
- Supports hot Plug and Play and remote wake-up of peripherals
- Supports individual power switching and individual overcurrent protection for downstream ports
- Supports partial dynamic port-routing capability for downstream ports that allows sharing of the same physical downstream ports between the Original USB Host Controller and the Hi-Speed USB Host Controller
- Supports legacy PS/2 keyboards and mice
- Uses 12 MHz crystal oscillator to reduce system cost and EMI emissions
- Operates at +3.3 V power supply input
- Full industrial operating temperature range from -40 Cel to +85 Cel
- Full-scan design with high fault coverage (93 pct to 95 pct) ensures high quality
- LQFP128 package available
