RTL8019AS
2. General Description
The RTL8019AS 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 RTL8019AS 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
RTL8019AS also supports the jumper and proprietary jumperless options.
To offer a fully
plug and play
solution, the RTL8019AS provides the auto-detect capability
between the integrated 10BaseT transceiver, BNC 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 RTL8019AS supports 16k, 32k & 64k byte BROM and fiash memory interface. 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.
The RTL8019AS is built in with 16K-byte SRAM in a single chip. It is designed not only to
provide more friendly functions but also to save the effort of SRAM sourcing and inventory.
