Is there a fundamental reason why the PDM to PCM component is not available on the PSoC 5LP, only on PSoC 6?

This thread discusses two hardware solutions to the PDM to code conversion.

Interfacing iso. ADC like AD74XX

PDM_PCM is a fixed function block in PSoC6, that means PSoC6 hardware has support for it.

PSoC5LP on the other hand doesn't have hardware support for PDM_PCM in that way.

You can refer to this links for PCM/PDM support on PSoC5LP:
