Figure 2a—According to the stats, it looks like the Easy Ethernet W/PIC18 can run comfortably as a UDP client. However, the RAM usage would put the binders on a large user application. b—The package is pretty tight here. TCP consumes a lot of the PIC18F452’s ROM and RAM. Despite that, you can still run a small but useful TCP and UDP application. c—DHCP was the gas guzzler when I was riding on the W/PIC18. With UDP, TCP, and DHCP active plus an additional 478 bytes of receive buffer, I haven’t even reached the halfway point in ROM or RAM usage on the LAN buggy’s PIC18F8621. d—Wow! Suppose you only wanted to serve web pages. You could stuff the CMX-MicroNet HTTP service and a bunch of HTML pages into the bologna tube and probably still have room to spare.
