I'm currently looking at the DS80C400. That is
one scary chip.
Hardware math accelerator, 10/100Mbps ethernet controller, TCP/IP
stack and multitasking OS primitives in on-chip ROM...most impressive.
I've got
some samples. Unfortunately it's beginning to look like I might
have to buy and cannibalise an Ethernet card. Unless someone here has a
spare they want rid of. I need the Ethernet interface transformer and RJ45
socket to be intact at the very least.
This is a microcontroller that can, no shit, boot
its firmware via
DHCP and TFTP.
That settles it - I've got a spare 256kbit RAM lying around
somewhere that's
just begging to be used, plus I've got a spare MAX233 (SOIC SMD) and some
odd-job parts. This 80C400 is getting turned into a webserver :-)
Later.
