Lpc2000

I am about to embark on my first LPC2106 project. I chose this product 
for its small size and cost for a single chip solution for a data logger.

I also need counters + RTC; I also need a low power consumption. I want 
10 years operation from a single lithium cell.

The intention is to feed the pulse inputs into D Flip flops (to catch 
them) and then feed them into interrupt inputs. The RTC will be handled
by an external component (probably a maxim chip) in the same way. I 
intend to keep the product in power down mode most of the time
(10 microamps I believe).  I would be interested in anyones comments on 
this use of the processor.

I was interested in Phiips comments about a new development with these 
components. Unfortunately I can't wait. If they are prepared to accept 
comments from us, then they could look at the PIC16F877 / PIC16F452. It 
has a rubbish processing core, but a great I/O system. I love the 
"interrupt on change" inputs. I have had these components, together with 
a whole board, operating at 25 microamps using the on board 32KHz 
oscillator. The  main clock wakes up every RTC interrupt (every second) 
and whenever an external event happens.I get full processing capablity 
with negligible power consumption. Pity about the processing core and 
it's innumerable silicon bugs, else I would be still using this series.
