Lpc2000

Here are my two cents.
I would like to see three versions of an eval. board
with LPC2888:

- Lite;
- Standard;
- Sophisticated;

All with the same connector for a motherboard.

Lite:
- XTAL;
- Power supply regulator;
- Decoupling caps;
- USB connector;
- JTAG header;
- GPIO's on a standard 0.1" header;

Standard:
- All the above plus External memory and Serial
port(s);

Sophisticated:
- All the above plus FPGA and Ethernet controller;

The motherboard design can be left to the user.


Regards
Zdravko Dimitrov
