RTL8019AS-LF

The RTL8019AS-LF belongs to the series of RTL8019AS. There is some information about RTL8019AS.

The RTL8019AS-LF is a kind of integrated ethernet controller. RTL8019AS-LF provides a simple solution to implement a Plug and Play NE2000 compatible adapter with full-duplex and power down features. RTL8019AS-LF supports 16k, 32k & 64k byte BROM and fiash memory interface. Besides, the page mode function is also available which can support up to 4M-byte BROM within only 16k-byte system memory space. RTL8019AS-LF is built in with 16K-byte SRAM in a single chip.

The following is about the features of RTL8019AS-LF. First is 100-pin PQFP and RTL8019 software compatible. Secondly, it supports PnP auto detect mode (RTL8019AS only). Then is compliant to Ethernet II and IEEE802.3 10Base5, 10Base2, 10BaseT. Next is software compatible with NE2000 on both 8 and 16-bit slots. In addition, it supports both jumper and jumperless modes. Besides, it supports Microsoft's plug and play configuration for jumperless mode. Furthermore, it supports Full-Duplex Ethernet function to double channel bandwidth. The eighth one is that it supports BROM disable command to release memory after remote boot and flash memory read/write (RTL8019AS only). The last one is capable of programming blank 9346 on board for manufacturing convenience.

What comes next is about the absolute maximum ratings of RTL8019AS-LF. The operating temperature is from 0 to 70. The storage temperature is from -65 to 140. All outputs and supply voltages, with respect to ground is from -0.5 to 7 V.
