Hi Guys,

   

I was going through the datasheet of PSoC 4 BLE - CY8C4248. For my application , I need 12 analog inputs ( 0 - 5V range) which i need to measure/sample through the SAR ADC. Timing is not so crucial, so I can afford to serially scan all the channels. I see that there is a SARMUX, but it seems to be a hardware sequencer for 8 channels. Is it possible to get 4 more or should I go for an external mux?

   

Secondly, I need 6 PWM channels working simultaneously with different duty cycles. I see that there are only 4 fixed timers. Can i use the UDB to create more PWM channels?

   

I am using PSoC 4 BLE, since i need the above two features along with BLE.

   

Is all above possible?

   

 

   

Regards.

Welcome in the forum!

   

Datasheet of sequencing ADC tells on first page "up to 16 channels".

   

Yes, you may use the UDB implementation of PWMs. There are 4 available and each is 8 bit wide.
