I know in some peripherals, like in a lot of times, the external clock is resynchronized to the CPU clock.In an ADC, that could add jitter. Does anyone know if using an external sample clock on a SAR ADC will be resynchronized to the CPU clock or wil...

I'm considering using the internal PLL to generate a clock for a precision ADC. My sample rate is low, so it's possible this may work. I need less than 50 ps RMS phase period jitter.Looking in the datasheet at the specs for PLL1, I'm having difficult...

It's my understanding that it is a bad idea to mix lead-free and leaded solder, and that it can cause cracks.I'm using a TFBGA100 package on an STM32H7 and have some long-term reliability requirements. In order to avoid tin-whiskers, I was considerin...

I'm looking at the STM32H7B0xB. I'm confused about what the actual maximum baud rate of the UART (in asynchronous mode) is. I'm getting three conflicting answers:Section 3.38 (the USART section of the datasheet) says: "These interfaces provide asynch...

I am going to have an external high speed signal as input to the MCU. I want to use a 32-bit timer to count the number of cycles on that input. Will a regular timer keep counting even in CSLEEP or CSTOP modes? Or do I need to use an LPTIMER. The LPTI...
