RTL8100B(L)
Datasheet
1. General Description
The Realtek RTL8100B(L) is a highly integrated and cost-effective single-chip Fast Ethernet controller
that provides 32-bit performance, PCI bus master capability, and full compliance with IEEE 802.3u
100Base-T specifications and IEEE 802.3x Full Duplex Flow Control. It also supports Advanced
Configuration Power management Interface (ACPI), PCI power management for modern operating
systems that are capable of Operating System Directed Power Management (OSPM) to achieve the most
efficient power management possible. The RTL8100B(L) also supports shared Boot ROM pins & clock run
pin.
In addition to the ACPI feature, the RTL8100B(L) also supports remote wake-up (including AMD Magic
Packet, LinkChg, and Microsoft® wake-up frame) in both ACPI and APM environments. The
RTL8100B(L) is capable of performing an internal reset through the application of auxiliary power. When
auxiliary power is applied and the main power remains off, the RTL8100B(L) is ready and is waiting for the
Magic Packet or Link Change to wake the system up. Also, the LWAKE pin provides 4 different output
signals including active high, active low, positive pulse, and negative pulse. The versatility of the
RTL8100B(L) LWAKE pin provides motherboards with Wake-On-LAN (WOL) functionality.
The RTL8100B(L) also supports Analog Auto-Power-down, that is, the analog part of the RTL8100B(L)
can be shut down temporarily according to user requirement or when the RTL8100B(L) is in a power down
state with the wakeup function disabled. In addition, when the analog part is shut down and the IsolateB pin
is low (i.e. the main power is off), then both the analog and digital parts stop functioning and the power
consumption of the RTL8100B(L) will be negligible. The RTL8100B(L) also supports an auxiliary power
auto-detect function, and will auto-configure related bits of their own PCI power management registers in
PCI configuration space.
PCI Vital Product Data (VPD) is also supported to provide the information that uniquely identifies
hardware (Ex., the OEM brand name of RTL8100B(L) LAN card). The information may consist of part
number, serial number, and other detailed information.
To provide cost down support, the RTL8100B(L) is capable of using a 25MHz crystal or OSC as its internal
clock source.
The RTL8100B(L) keeps network maintenance costs low and eliminates usage barriers. It is the easiest way
to upgrade a network from 10 to 100Mbps. It also supports full-duplex operation, making 200Mbps
bandwidth possible at no additional cost. To improve compatibility with other brands’ products, the
RTL8100B(L) is also capable of receiving packets with InterFrameGap no less than 40 Bit-Time. The
RTL8100B(L) is highly integrated and requires no “glue” logic or external memory.
The RTL8100B(L) includes a PCI and Expansion Memory Share Interface (Realtek’s patent pending) for a
boot ROM and can be used in diskless workstations, providing maximum network security and ease of
management.
