Re: LPC22XX usage

2005-01-18 by Gus

I have ben using LPC21 for a while and now thinking about using 
LPC22 for a new project. Same as you, I would like to know if people 
haveing issues with it.

- What RAM chips everyone is using?
- What FLASH is used?
- Anything else we should be aware as far as the external bus?
- From my understanding, the external bus have a fixed speed for the 
whole address range, is this true? I mean, if we have fast RAM and 
slow FLASH on the same chip we would have to run the chip to the 
speed of the slow device (FLASH in this example.)

Thanks,

Gus

range which leads me to think that everyone's using a 21XX device. 
This can't be the case, can it?
