Lpc2000

I just recieved 3 pieces of the LPC2214FBD144 (144 pin part) from 
philips as samples.  I was working on a rather complicated atmel 
AT91RM9200 design with all the bells and whistles, but since these 
parts arrived so quickly, I am considering putting that design on 
hold for a bit and getting something actually working by using the 
LPC2214.  Just to get something going, I am considering stripping my 
design down to the following:

LPC2214FBD144
2 channel 16 bit DAC on SPI #1
8 channel 8 bit DAC on SPI #2
16 bit compact flash connector interface on the external memory 
controller
RS485 level converter on UART0
RS232 level converter on UART1
output buffers for DACS (+/-10 volts on the 16 bit DACS, 0-5 volts on 
the 8 bit, unless I find a 8 channel 8 bit dac with 0-5 volt buffers 
built in)
Simple linear voltage regulators

To keep things as simple as possible, I will supply regulated 5V and 
+/- 12V externally, and use onboard 1.8v,3.3v,10v,-10v linear 
regulators.  I will bring out the rest of the IO to .1 inch headers, 
and also perhaps the address/data bus to .1 inch headers for 
experiments.

Do you think this simple design is remotely possible on a 2 layer 
board?  I would love to keep it at two layers for cost reasons.

Thanks,

Rick
