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.

特性 Features

■ Complies with Universal Serial Bus Specification Rev. 2.0

■ 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 comply with Open Host Controller Interface Specification for USB Rev. 1.0a

■ One Hi-Speed USB EHCI core complies with Enhanced Host Controller Interface Specification for Universal Serial Bus Rev. 1.0

■ Supports PCI 32-bit, 33 MHz interface compliant with PCI Local Bus Specification Rev. 2.2, with support for D3cold standby and wake-up modes; all I/O pins are 3.3 V standard

■ Compliant with PCI Bus Power Management Interface Specification Rev. 1.1 for all hosts (EHCI and OHCI), and supports all power states: D0, D1, D2, D3hot and D3cold

■ CLKRUN support for mobile applications, such as internal notebook design

■ Configurable subsystem ID and subsystem Vendor ID through external EEPROM

■ Digital and analog power separation for better ElectroMagnetic Interference (EMI) and ElectroStatic Discharge (ESD) protection

■ 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

■ Uses 12 MHz crystal oscillator to reduce system cost and EMI emissions

■ Supports dual power supply: PCI Vaux(3V3) and VCC

■ Operates at +3.3 V power supply input

■ Low power consumption

■ Full industrial operating temperature range from ?40 °C to +85 °C

■ Full-scan design with high fault coverage (93 to 95 ) ensures high quality

■ Available in LQFP100 package

Applications

■ Digital consumer appliances

■ Notebook

■ PCI add-on card

■ PC motherboard

■ Set-Top Box (STB)

■ Web appliances
