Lpc2000

Hi Bill,
Can you tell me any more on the new LPC devices, do they support 
SDRAM? Does the external memory use their "cache"?

Further clarfication on OKI..... The 674K series are rated at 33MHz 
and the 675K at 60MHz, both families have internal flash options as 
well as other perihperals....
On support I think Oki can give good support to customers, they 
provide full documentation and a range of sample code for their 
MCU's. Also support for many compiler/debugger options, eg 
ADS,RealView, GHS, Ashling, Nohau and GNU.....
