Can the PIC16F1703 do PWM through a peripheral?

[JoeP]

Datasheet: http://ww1.microchip.com/downloads/en/DeviceDoc/40001722C.pdf

The datasheet seems to be slightly contradictory; it has 2 CCP modules which can be configured to do PWM, but it also says it has 0 PWM  modules (top of page 2). Presumably it's just not counting the CCP as PWM, and that it is perfectly capable of doing PWM without using the processor, but does anyone know for sure?

Thanks.

Read the CCP section of the datasheet.
Some PICs have dedicated PWM as well as CCP. CCPs generally can do PWM

There are some newer PICs where CCP modules cannot do PWM - that is you cannot put CCP into PWM mode. Such PICs usually have separate PWM modules instead. I don't believe PIC16F1703 is one of them, so most likely this is a typo, but I wouldn't be 100% sure.

Look at page 12. It shows RC5 as CCP1, "Capture/Compare/PWM1". And RC3 is CCP2, "Capture/Compare/PWM2".

It is a little confusing, as those list CCP1 and CCP2 as inputs next to RC5 and RC3, but below, the table connects CCP1 to PWM1 and CCP2 to PWM2 outputs.

The PWM info starts at page 189, and it looks like any other PIC description. So I would assume, yes, the 16f1703 does have two PWM outputs available.

because the CCP module is not a PWM module. They are listing what modules are available and how many. They are not listing what functions those modules contain, so they don't say you have 2 pwm modules, because you don't. In a 1703 you have 2 CCP modules, and those modules have pwm capability (the P in CCP). If you want to see the difference, look at the 1704 datasheet.

You have CCP1 and CCP2 (2 CCP modules) which can both output pwm to almost any pin via pps. You can also route a pwm output to multiple pins if wanted (pps). When you look at the 1704 datasheet, you will find the pwm modules also listed as available pps output functions (and probably discover pps is quite nice to have).

can you share a partnumber?

Nope. I've just looked at all the new PIC16 datasheets and haven't found any. Must be glitches in my memory
