Product data sheet
8.1 PCI interface
The PCI interface has two functions. Function #0 is for the OHCI Host Controller and
function #2 is for the EHCI Host Controller. These functions support both master and
target accesses, and share the same PCI interrupt signal INTA#. These functions provide
memory-mapped, addressable operational registers as required in Open Host Controller
Interface Specification for USB Rev. 1.0a and Enhanced Host Controller Interface
Specification for Universal Serial Bus Rev. 1.0 .

(2) This electrolytic or tantalum capacitor must be of LOW ESR type (0.2
(3) The use of ferrite bead is optional. Can be directly tied to ground.
(4) This electrolytic or tantalum capacitor is needed only on pin 2.
(5) This electrolytic or tantalum capacitor is needed only on pin 18.
Remark: The 100 nF capacitor is needed on each individual pin, and is not shared among the
listed pins.
Remark: The figure shows the LQFP pinout. For the TFBGA ballout, see
