STM32 part with the most avialable rotary/quadrature encoder inputs

[JU_it]

Let me start by saying:

• Yes I know the STM32 Finder exists, no it doesn't help me find what I need
• Yes I've seen this thread but I do not want to get into manually coding a script to try and find parts if I can avoid it
• Yes I have used the CubeMX and no it can't filter for this requirement

Basically I'm after an STM32 that will allow me to interface the maximum number of rotary encoders possible into timer inputs (no I do not want to bit-bang it).

That's it - any suggestions welcome!

Usually any regular TIM the has 2 pins/channels. Most will 16-bit

At most only 2 32-bit TIM

Lots of timer channels that have 2-pins are up-count only, for example G071 has TIM1,2,3,4,6,7,14,15,16,17,and LPTIM 1 & 2 but only 4 timers out of that lot can actually work for encoder inputs (TIM1,2,3,4) hence my question.

AN4013 would be a good place to list available timers with encoder mode or at least the up/down count possibility.

A little bit OT / probably not helpful:

About 2 years ago I tried to add a special kind of pulse measurement to the audio / measurement data, synchronized to the audio sampling, options for IE included. The synchronization actually killed it, took too much CPU power to fiddle pulse / IE data into the audio stream.
So I finally came to the conclusion that our current FPGA-based solution (just switched from Xilinx to Efinix) plus MCU was still the better solution.
