Lpc2000

Hi,

I want to replace my current Atmega128L project (running at 8MHz) 
with a LPC2114 (also to be run at 8MHz). My motive of doing this is 
that LPC2114 is more powerful and is better prepared for future 
upgrade.

However, my project is battery operated. My concern is on the power 
consumption. From lpc2114 datasheet:

1) 3.3V I/O power: since this depends on the load, so this should be 
same as Atmega128L. Is this correct assumption?

2) 1.8v Core power: according to datasheet, lpc2114 running at 60MHz 
draws about 30mA. Can I assume that lpc2114 draws 4mA when running at 
8MHz?

Thanks,
