Realtek RTL8139 (network chip)

Designed only for Realtek RTL8139C RTL8139C-LF RTL8139CL RTL8139CL-LF
The Realtek RTL8139C(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 RTL8139CL is suitable for applications such as CardBus or mobile devices with a built-in network controller. The CIS data can be stored in either a 93C56 EEPROM or expansion ROM.

In addition to the ACPI feature, the RTL8139C(L) also supports remote wake-up (including AMD Magic Packet, LinkChg, and Microsoft wake-up frame) in both ACPI and APM environments. The RTL8139C(L) is capable of performing an internal reset through the application of auxiliary power. When auxiliary power is on and the main power remains off, the RTL8139C(L) is ready and 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 RTL8139C(L) LWAKE pin provides motherboards with the Wake-On-LAN (WOL) function. The RTL8139C(L) also supports Analog Auto-Power-down, that is, the analog part of the RTL8139C(L) can be shut down temporarily according to user requirements or when the RTL8139C(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 power consumption of the RTL8139C(L) will be negligible. The RTL8139C(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.

The PCI Vital Product Data (VPD) is also supported to provide the information that uniquely identifies hardware (i.e., the RTL8139C(L) LAN card). The information may consist of part number, serial number, and other detailed information.

To provide cost down support, the RTL8139C(L) is capable of using a 25MHz crystal or OSC as its internal clock source.

The RTL8139C(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 RTL8139C(L) is also capable of receiving packets with InterFrameGap no less than 40 Bit-Time. The RTL8139C(L) is highly integrated and requires no “glue” logic or external memory. It includes an interface for a boot ROM and can be used in diskless workstations, providing maximum network security and ease of management.

Designed only for Realtek RTL8139D RTL8139DL RTL8139D-LF RTL8139DL-LF RTL8139D-GR RTL8139DL-GR
The Realtek RTL8139D(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 RTL8139D(L) also supports shared Boot ROM pins & clock run pin.

In addition to the ACPI feature, the RTL8139D(L) also supports remote wake-up (including AMD Magic Packet, LinkChg, and Microsoft® wake-up frame) in both ACPI and APM environments. The RTL8139D(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 RTL8139D(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 RTL8139D(L) LWAKE pin provides motherboards with Wake-On-LAN (WOL) functionality.

The RTL8139D(L) also supports Analog Auto-Power-down, that is, the analog part of the RTL8139D(L) can be shut down temporarily according to user requirement or when the RTL8139D(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 RTL8139D(L) will be negligible. The RTL8139D(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 RTL8139D(L) LAN card). The information may consist of part number, serial number, and other detailed information.

The RTL8139D(L) is highly integrated and requires no “glue” logic or external memory.

The RTL8139D(L) provides a flexible multi-function mode (Realtek patent pending) to incorporate other PCI master devices, like a hardware modem. When in multi-function mode, the RTL8139D(L) acts as an arbiter to distinguish LAN signals from those of other devices. The second device recognizes no difference between being connected to the RTL8139D or a regular PCI bus.

The RTL8139D(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.
