Description

The RTL8019 is a highly integrated Ethernet Controller which offers a simple solution to implement a Plug and Play NE2000 compatible adapter with full-duplex and power down features. With the three level power down control features, the RTL8019 is made to be an ideal choice of the network device for a GREEN PC system. The full-duplex function enables simultaneously transmission and reception on the twisted-pair link to a full-duplex Ethernet switching hub. This feature not only increases the channel bandwidth from 10 to 20 Mbps but also avoids the performance degrading problem due to the channel contention characteristics of the Ethernet CSMA/CD protocol. The Microsoft's Plug and Play function can relieve the users from pains of taking care the adapter's resource configurations such as IRQ, I/O, and memory address, etc. However, for special applications not to be used as a Plug and Play compatible device, the RTL8019 also supports the jumper and proprietary jumperless options.

To offer a fully plug and play solution, the RTL8019 provides the auto-detect capability between the integrated 10BaseT transceiver and AUI interface. Besides, the 10BaseT transceiver can automatically correct the polarity error on its receiving pair. Furthermore, 8 IRQ lines and 16 I/O base address options are provided for grand resource configuration flexibility.

The RTL8019 supports 16k, 32k & 64k byte BROM. It also offers the page mode function which can support up to 4M-byte BROM within only 16k-byte system memory space. Besides, the BROM disable command is provided to release the BROM memory space for other system usage (e.g. EMM386, etc.) after the BROM program is loaded.
