RTL8100C Datasheet PDF - Realtek Semiconductor

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 DuplexFlow 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).
