mk22fn512 dac output

hancav — Mon, 21 Mar 2016 19:38:37 GMT

Hello

I am new to K series processors and i selected "mk22fn512vlh12" 64 LQFP for a new project.

I need to have two independent DAC outputs besides at least two ADC inputs.

I have been reading several docs that says that this part has 2x DAC (12bit) however i can't find the pin of the second DAC output on the datasheet.

Reading the datasheet: "k22p121m120sf7.pdf" on page 63 table i see that DAC0 is on pin 18, but DAC1 is only on pin k4 of the (121BGA) package, page 73, is this correct ? There isn't DAC1 output for 64LQFP package ?

I need to use a LQFP package, to have 2x DAC and 2x ADC, 2Uarts and SPI, RTC and 128k of flash is enough, i have FRDM-K22F for development, what would be the best part for my project ??

Thank you very much for your time and attention

Hi Hugo,

After have reviewed quite a few reference manual, I think the MK22FN512VLH12 only have the one DAC module.

However I'll confirm it with the AE team later and inform you ASAP if I get the reply.

About your requirement, I'd like to suggest that you can choose the MK24FN1M0VLL12 instead of the MK22FN512VLH12.

And you can learn the more information about the through the link as below.

Hope it helps.
Have a great day,

It would be a great help if you could help me with this doubt.

I would prefer to use mk22fn512 às i have already several resources for it.

Thank you very much
