3.3V PS

[ast8346]

Hello

In terms of single 3.3V power supply mode for XMOS, does it matter what current rating will be? 

Say I am using 3.3 V, 5A supply, would it be better that using 3.3V, 0.9A supply?

Basically the question is how high\low resistance on VCC input of XMOS device is recommended to be?

Regards,

You don't mention which IC.. In general, check the worst case current for that rail in the datasheet, the minimum voltage input and then use ohms law ;-)

I'd be very worried if any XMOS ICs needed as much as 0.9Amps, let alone 5Amps!!
