LAN9730(i)
High Speed Inter-Chip (HSIC) USB 2.0 to 10/100 Ethernet Controller
Summary
Microchip’s LAN9730 was specifically designed to provide
a high-performance, low-cost USB to 10/100 Ethernet
connectivity solution with a High Speed Inter-Chip (HSIC)
interface. Taking advantage of the broad availability of
existing USB drivers and software, Microchip’s proprietary
HSIC technology incorporates a 2-pin digital bus that
enables the use of USB as a low-power, chip-to-chip
interconnect at speeds up to 480 Mbps. The internal
device controller is USB 2.0-compliant and the HSIC
interface is HSIC USB Electrical Specification Revision
1.0-compliant. The device implements Control, Interrupt
and Bulk-in and Bulk-out USB endpoints. Microchip’s
UniClock™ technology simplifies the clocking scheme
and reduces system BOM costs by using a single 25 MHz
crystal for both USB and Ethernet connectivity—without the
need for additional components when adding USB hubs.
Applications well-suited for the LAN9730 and LAN9730i
(industrial temperature range option) include embedded
systems, set-top boxes, PVRs as well as USB port
replicators and test instrumentation. The LAN9730 also
supports auto-negotiation, auto-polarity correction, HP
Auto-MDIX* and is compliant with IEEE 802.3 and 802.3u
standards. An external MII interface provides support
for an external PHY which enables HomePNA® (HPNA)
or HomePlug® functionality. Multiple power management
features are provided, including various low-power modes,
as well as Magic Packet, Wake-on-LAN and Link Status
Change wake events. These events can be programmed
to initiate a remote USB wakeup. A PCI-like PME wake is
also supported when the USB host controller is disabled.
Additionally, Microchip offers its complimentary and
confidential LANCheck® online design review services to
customers who select our products for their application
design-in.**

HSIC interface

The low pin count interface enables
printers, mobile PCs, ultra-mobile
PCs, PCs and tablets to reduce
their power budget while taking full
advantage of USB connectivity.

Software compatibility

HSIC software and driver are fully
backward-compatible with USB 2.0
software and drivers, enabling a
seamless transition to HSIC.
