K64F FTM capabilities?

davenadler — Thu, 28 Jul 2022 18:40:10 GMT

Where are implemented FTM capabilities documented?
In Kinetis K64F Sub-Family Data Sheet it lists 4 FTM:
• Two 8-channel Flex-Timers (PWM/Motor control)
• Two 2-channel FlexTimers (PWM/Quad decoder)

Which FTM have what capabilities?
Do all FTM have quadrature decoder?
I can't seem to find this in the documentation...

Thanks!
Best Regards, Dave

Hi Dave,

Not all of the FTMs have quadrature decoders.

The two 2-channel FTMs (FTM1 and FTM2) each have a quadrature decoder.

The two 8-channel FTMs (FTM0 and FTM3) each have a 3-phase motor and 2 general purpose or stepper motors.

In case you need any more information on the K64F, I think the K64 Sub-Family Reference Manual is the document you were missing. You mentioned the data sheet but not the reference manual in your post so I wanted to make sure you had access to both.

Here is the link to the K64F on the NXP website:

https://www.nxp.com/products/processors-and-microcontrollers/arm-microcontrollers/general-purpose-mcus/k-series-cortex-m4/k6x-ethernet/kinetis-k64-120-mhz-256-kb-sram-microcontrollers-mcus-based-on-arm-cortex-m4-core:K64_120

At the bottom of the page there is a section with all of the documentation for this device. The document I used to answer your question was the “Kinetis K64: 120MHz Cortex-M4F up to 1MB Flash 100-144pin” under reference manuals. Specifically, page 137.

Thank you for your question!
