ISP1564HLUM

General description

The ISP1561 is a 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 withUniversal Serial Bus Specification Rev. 2.0,

Features

■Complies withUniversal 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 withOpen Host Controller Interface Specification for USB Rev. 1.0a
■One Hi-Speed USB EHCI core complies withEnhanced 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. 2.2with support for the D3coldstandby and wake-up modes; all I/O pins are 3.3 V standard, but 5 V-tolerant
■Compliant withPCI Bus Power Management Interface Specification Rev. 1.1 for all hosts (EHCI and OHCI), and supports all power states:D0, D1, D2, D3hotand 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.
