Lpc2000

Hi Peter

They sure are. See data sheet - Static characteristics - Table 9 - 
Standard Port Pins, RST, RTCK and DBGSEL 0..5.5V, which are 
basically all pins apart from the 1.8V core voltage and the 
oscillator pins.

I am working with this chip using a mixture of 3.3V and 5V I/O and 
am also driving the serial ports and RST from 5V with no problems.

The only thing to respect is the little note in the data sheet 
("VDD3 supply voltages should be present") - so best not have 5V 
present if the power is removed from the LPC2016.


Cheers
