Hi,currently, I am using an NX2016SA (as recommended by ST) to generate the HSE (32 MHz) for an STM32WB55RGV6 microcontroller.I did not calibrate it, but so far everything works and I have a BLE range of up to 25 meters.Now I am planning to getting m...

Hi,as I understand it:I can activate the low power manager in CubeIDE. This will automatically add code, so each time the Sequencer has nothing to do, the system enters low power mode.So far, this works. I can see it in the current consumption.What I...

Hi,is there an error in the datasheet? The data seems counterintuitive:FT pin input leakage current (max.) is- 150 nA for 0 to VDD-2500 nA for VDD to VDD+1V-250 nA for VDD+1V to 5,5VShouldn´t the last value be in uA perhaps?Kind regardsRené

Hi,I am currently optimizing some designs and started thinking about decoupling capacitors. As far as I know, it is a rule of thumb to place "one 100 nF capacitor per V+ pin".In the attached document, ST recommends exactly this. Let´s look at the doc...

Hi,I just found an error in the data sheet and wanted to let you guys know. Don´t know who else to contact.Kind regardsRené

In the datasheet of the STM32WBXX you find the different sleep modes and what peripherals are active during these sleep modes. Usually, if you are using the low power manager (from CubeIDE), the HSE is deactivated in STOP1 mode I think.But how do you...

ST, please fix

I did some more digging here https://community.st.com/t5/stm32-mcus-wireless/ble-sleep-mode-and-hse/m-p/615804#M17134 Unfortunately, ST has not responded yet. It seems that CPU2 also manages an external crystal and turns it on for advertising and off...
