PI7C9X442SL

PCI Express® (PCIe®) to USB® 2.0 Swidge
Product:
Part Numbers: PI7C9X442SL
USB 2.0 Host Controller Features
Product Description
The PI7C9X442SL PCI Express® to USB® 2.0 Swidge is
designed to meet the latest low-power, lead (Pb)-free and green
system requirements. The PI7C9X442SL is a cost-effective
solution that can be implemented in systems such as volume
servers, embedded systems, motherboards, laptops, docking
stations, peripherals, PC add-in cards and other footprint
sensitive platforms requiring multiple USB host connections.
USB Root hub with 4 (max.) downstream facing ports which
are shared by OHCI and EHCI host controllers
All USB downstream facing ports can handle High Speed
(480 Mbps), Full Speed (12 Mbps) and Low Speed (1.5
Mbps) transactions
PCI multi-function device consists of two OHCI host
controllers for Full Speed/Low Speed signaling and one
EHCI host controller for High Speed signaling
USB Host Controller operational registers directed-mapped
to PCI
The PI7C9X442SL provides one x1 upstream PCIe port, two x1
downstream PCIe ports, and up to 4 USB 2.0 host controller
ports. The PI7C9X442SL provides users the flexibility to expand
or fan-out from a wide range of I/O Bridges such as IOH, PCH,
ICH, embedded MCU and other Application Specific ICs.
