UPD720102数据手册集成电路（IC）的控制器规格书PDF

描述 Description

The μPD720102 complies with the universal serial bus specification revision 2.0 and open host controller interface specification for full-/low-speed signaling and Intel's enhanced host controller interface specification for high-speed signaling and works up to 480 Mbps. The μPD720102 is integrated 2 host controller cores with PCI interface and USB 2.0 transceivers into a single chip.FEATURES
• Compliant with universal serial bus specification revision 2.0 (data rate: 1.5/12/480 Mbps)
• Compliant with open host controller interface specification for USB release 1.0a
• Compliant with enhanced host controller interface specification for USB revision 1.0
• PCI multi-function device consists of one OHCI host controller core for full-/low-speed signaling and one EHCI host controller core for high-speed signaling
• Root hub with 3 (Max.) downstream facing ports which are shared by OHCI and EHCI host controller cores
• All downstream facing ports can handle high-speed (480 Mbps), full-speed (12 Mbps), and low-speed (1.5 Mbps) transaction
• Supports hyper-speed transfer mode using HSMODE signal
• 32-bit 33 MHz host interface compliant with PCI specification revision 2.2
• Supports PCI mobile design guide version 1.1
• Supports PCI-bus power management interface specification revision 1.1
• PCI bus bus-master access
• Supports 3.3 V PCI
• System clock is generated by 30 MHz crystal or 48 MHz clock input
• Operational registers direct-mapped to PCI memory space
• 3.3 V single power supply, 1.5 V internal operating voltage from on chip regulator
• On chip Rs and Rpd resistors for USB signals
