SC92031
10/100 MBPS INTEGRATED PCI ETHERNET MEDIA ACCESS
CONTROLLER AND PHYSICAL LAYER
DESCRIPTION
The SC92031 is a highly-integrated and cost-effective single-chip
Fast Ethernet NIC controller. It fully complies with PCI 2.2 and IEEE
802.3u 100Base-T specifications. It supports both half-duplex and full -
duplex operation, as well as for full-duplex flow control. It also supports
Advanced Configuration Power management Interface (ACPI), PCI
power management and remote wake-up events including AMD Magic
Packet, Link Change, and Microsoft® wake-up frame.
The SC92031 provides glue less 32-bit bus master interface for PCI,
boot ROM interface, as well as physical media interface for 100BASE-
TX of IEEE 802.3u and 10BASE-T of 802.3. It also supports shared
Boot ROM pins & clock run pin.
The SC92031 supports Analog Auto-Power-down, that is, the analog
part of the SC92031 can be shut down temporarily according to user
requirement or when the SC92031 is in a power down state with the
wakeup function disabled.
PCI Vital Product Data (VPD) is also supported to provide the
information that uniquely identifies hardware. The information may
consist of part number, serial number, and other detailed information.
To provide cost down, the SC92031 is capable of using a 25MHz
crystal or OSC as its internal clock source.
The SC92031 includes a PCI and Expansion Memory Share Interface
for a boot ROM and can be used in diskless workstations, providing
maximum network security and ease of management.
The SC92031 provides a flexible multi-function mode to incorporate
other PCI master devices. When in multi-function mode, the SC92031
acts as an arbiter to distinguish LAN signals from those of other
devices.
