I want to comunicate my pc with TCP/IP protocols. My hardware will contain 18F452 and RT8019. Is it ok for TCP/IP comunications?
I ask this question because, I have had alot of information onthe pic. RS232 is not enough to tranfer this information(baud:115200). So, I decided to transfer these with TCP/IP.
I would use a 18F6720. It has 128K of rom and 3840 bytes of ram. Comes in a 64pin TQFP package so is about the same size, but you could implement a 16 bit interface and have more ram for a buffer.
If you are mean to get the driver information of RTL8019, here below
AN475: DP8390 Network Interface Controller: An Introductory Guide DP8390D/NS32490D NIC Network Interface Controller
AN874: Writing Driver for the DP8390 NIC Family of Ethernet Controllers
AN886: The Operation of the FIFO in the DP8390, DP83901, DP83902, and DP83905
AN937: Loopback Diagnostics Using the DP8390/901/905
Search at google first, if still get it tell me.
And, we are defining the MAC address at the TCP/IP stack at link layer. Go study the TCP/IP stack for your understanding.
I didn't mean where can I get driver information.. I meant where can I physically buy the part. I find that it's a hard part to find, and I cannot buy it in small quantities.

If you want to buy a single chip I can recommend www.voti.nl
The chip costs almost 10 euro (9.37 to be exact) but you can purchase a single chip if you want.
Microchip did offer you their free TCP/IP stack. Now the C18 compiler is offered as Student Edition and you could use it after expire of 60 days try period.

Also check their demo board. You can find the schematic in the user's guide.
