Interface ISA
The RTL8019AS-LF is a full-duplex ethernet controller with plug and play function.
The RTL8019AS integrates the RTL8019A and 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 source and inventory.
Features:
100-pin PQFP
16 K byte SRAM built in
Compliant to Ethernet II and IEEE802.3 10Base5, 10Base2, 10BaseT
Supports UTP, AUI & BNC auto-detect
Software compatible with NE2000 on both 8 and 16-bit slots
Supports jumper, jumperless and PnP modes
Supports PnP auto detect mode
Supports Full-Duplex Ethernet function to double channel bandwidth
Supports three level power down modes:
Sleep
Power down with internal clock running clock
Power down with internal halted
Built-in data prefetch function to improve performance
Supports auto polarity correction for 10BaseT
Support 8 IRQ lines
Supports IO address fully decode mode
Supports 16 K, 32 K, 64 K and 16 K-page mode access to BROM (up to 256 pages with 16 K bytes/page), and Flash memory read/write
Supports BROM disable command to release memory after remote boot
Capable of programming blank 9346 on board for manufacturing convenience
Support 4 diagnostic LED pins with programmable outputs
Improves the blinking problem of CRS LED when the cable is not connected
