USB PCI host controller
Philips Semiconductors
2. 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. 0.95
■ Supports PCI 32-bit, 33 MHz interface compliant with PCI Local Bus Specification
Rev. 2.2 with support for the D3cold standby and wake-up modes; all I/O pins are
3.3 V standard, but 5 V-tolerant
■ 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
■ 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 to +85 °C
■ Full-scan design with high fault coverage (93% to 95%) ensures high quality
■ LQFP128 package available.
