I´m looking for a Kinetis with quadrature encoder input.
None found. Is it correct ?
All the kinetis microcontrollers feature one or more FlexTimers (FTM) which supports Quadrature decoder with input filters, relative position counting, and interrupt on position count or capture of position count on external event
See K-40 Series, With Flex timer peripheral.
Has option to Quadrature Decoder mode
Just one problem with that answer - it is not correct. Not all Kinetis MCUs have a an FTM.
It seems you are not the only one with this mistaken notion. On the Freedom Board they pinned it out as FTM, when in fact it is TPM.
The KL25 Has a TPM, quoting from the RM:
(Document Number: KL25P80M48SF0RM)
"The TPM is built upon a very simple timer (HCS08 Timer PWM Module – TPM) used
for many years on Freescale's 8-bit microcontrollers. The TPM extends the functionality
to support operation in low power modes by clocking the counter, compare and capture
registers from an asynchronous clock that can remain functional in low power modes"
I forgot to mention I was referring to the K family
