ADC And LPTIM in STM32L4

[fiim]

Hello! I once asked a question about ADC:

("adc-functionality-in-stm32f1-stm32l15x-series")

Since then, the ADC has gotten much,much better, thank you!

There are even versions with 16-bit. But there is still one serious problem. This is a built-in reference voltage source(VREF).

It sooo strongly depends on the temperature(especially true for temperatures below 20C). It turns out that the 16-bit ADC is useless. You have to use an external VREF;

Here is the actual question: are you planning to improve the VREF stability?

The second question is related to LPTIM. The task is as follows: You need to measure time intervals with a detail of 1 us(microsec).

And both in normal mode and in STOP mode. And these intervals can be several days or weeks.

A 16-bit timer is certainly not enough. Not enough and 32-bit))). You need a 64 or at least 48bit timer that can work in stop-mode.

You add some really cool stuff to the MC. Please add this absolutely necessary timer!))

Sincerely, fiim;
