Single-Chip Fast Ethernet Controller

Track ID: JATR-1076-21 Rev. 1.06

General Description

The Realtek RTL8100C(L) is a highly integrated, 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 the Advanced Configuration

and Power 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 RTL8100C(L) does not support CardBus mode (the RTL8139C does).

In addition to the ACPI feature, the RTL8100C(L) also supports remote wake-up (including AMD Magic

Packet, LinkChg, and Microsoft® wake-up frame) in both ACPI and APM (Advanced Power Management)

environments. The RTL8100C(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 RTL8100C(L) is

ready and waiting for a Magic Packet or Link Change to wake the system up. Also, the LWAKE pin

provides 4 output signals (active high, active low, positive pulse, and negative pulse). The versatility of the

RTL8100C(L) LWAKE pin provides motherboards with Wake-On-LAN (WOL) functionality.

The RTL8100C(L) also supports Analog Auto-Power-down. The analog part of the RTL8100C(L) can be

shut down temporarily according to user requirements, or when the RTL8100C(L) is in a power down state

with the wakeup function disabled. When the analog part is shut down and the IsolateB pin is low (i.e. the

main power is off), both the analog and digital parts stop functioning and the power consumption of the

RTL8100C(L) is negligible. The RTL8100C(L) also supports an auxiliary power auto-detect function, and

will auto-configure related bits of its PCI power management registers in PCI configuration space.

PCI Vital Product Data (VPD) is also supported to provide hardware identifier information. The

information may consist of part number, serial number, OEM brand name, and other detailed information.

To provide cost down support, the RTL8100C(L) is capable of using a 25MHz crystal or OSC as its internal

clock source.

The RTL8100C(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

RTL8100C(L) is also capable of receiving packets with an InterFrame Gap equal to or more than 40-bit

time. The RTL8100C(L) is highly integrated and requires no glue logic or external memory.
