New possibilities for the ultra-low power segment!

STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...

Does HyperRAM require terminations?

I'm having trouble figuring out if an STM32H7 needs terminations for a HyperRAM memory. The memory I'm using has variable drive strength on the HyperRAM side, so I won't need terminations for RAM->MCU direction.However, I can't find any information i...

Resolved! Unable to set two PWMs to a fixed phase difference

Hi,I am trying to set up two timers so that they generate a PWM with the second timer being 1/4 phase past the first one. I am using an STM32F446.I have the second set up as slave and triggered by the OCREF2 of timer 1, this should then generate a re...

STM33H733 + SDRAM?

Good morning everyone,Sorry for the (maybe) silly question. For a new design we would like to exploit the STM32H733ZG microcontroller. From its datasheet it seems that it supports a 16-bit SDRAM, and for our application it should be at least 16 MB la...

5V parasite power supply and 3V3 MCU

I have a requirement to use DS1820 temperature sensor in parasite mode, that needs 5V power supply (2 wires only) and STM32 MCU.It works with 3V3 power supply, but there is increased measurement time, and it stops working over like 80°C.I guess durin...

Timers first pulse is different and timers not in sync

Hi,I have spent a few days trying to get the timers in sync, that is use one timer with multiple outputs; oc,PWM,base. I am generating a 1MHz clock for an external device. And then a start pulse. When the timer overflows ADC starts. It needs to be ex...
