Description 1770839326Realtek RTL8100CL Single-Chip Fast Ethernet Controller with Power ManagementThe 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.
Key Features128-pin QFP/LQFP Integrated Fast Ethernet MAC, Physical chip, and transceiver in one chip 10Mbps and 100Mbps operation Supports 10Mbps and 100Mbps NWay auto-negotiation PCI local bus single-chip Fast Ethernet controller Complies with PCI Revision 2.3 Supports PCI clock 16.75MHz-40MHz Supports PCI target fast back-to-back transaction Provides PCI bus master data transfers and PCI memory space or I/O space mapped data transfers of the RTL8100C(L)’s operational registers Supports PCI VPD (Vital Product Data) Supports ACPI, PCI power management Supports 25MHz crystal or 25MHz OSC as the internal clock source. The frequency deviation of either crystal or OSC must be within 50PPM. Complies with the PC99/PC2001 standard Supports Wake-On-LAN and remote wake-up (Magic Packet*, LinkChg, and Microsoft® wake-up frame) Supports 4 Wake-On-LAN (WOL) signals (active high, active low, positive pulse, and negative pulse) Supports auxiliary power-on internal reset, to be ready for remote wake-up when main power remains off Supports auxiliary power auto-detect, and sets the related capability of power management registers in PCI configuration space Includes programmable PCI burst size and early Tx/Rx threshold Supports a 32-bit general-purpose timer, with the external PCI clock as clock source, for generating timer-interrupts Contains two (2Kbyte) independent receive and transmit FIFOs Advanced power saving mode when LAN and wakeup function are not used Uses 93C46 (64*16-bit EEPROM) to store resource configuration, ID parameter, and VPD data Supports LED pins for various network activity indications Supports loopback capability Half/Full duplex capability Supports Full Duplex Flow Control (IEEE 802.3x) 2.5/3.3V power supply with 5V tolerant I/Os 0.25µm CMOS process
