I prefer 12-bit resolution but 10-bit will work too. The need for the SPI port is for external RAM if there is not enough internal ram to buffer data. I need at least 128k of internal RAM to avoid using external RAM.

Hi,
I'm hoping somebody can give me some suggestions on a uC for a project I am doing. I need to sample 2 signals simultaneously at 1MSPS. Ideally I would like a part with at least 128k RAM so I don't have to buffer data external. If I do, then the uC will need to have 2 SPI ports @ 20MHz...
Hello,
I have a question about pcb trace spacing. What trace spacing should I use on my pcb for 12v signals. Nominally it should be a few mils minimum for a peak voltage of 15v on an outer layer. My question is in an automotive application, there could be short transient spikes of 100v due to...
