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...
I'm working on an application where the amount of wires is limited. In order to update firmware, the only thing I will have is a single half-duplex RS485 transceiver connected to the UART. I was going to connect this to a single UART pin in single-wi...
I'm considering using a QSPI RAM to expand the RAM of an STM32H7 device (not FLASH).If possible, I'd like to use memory mapped mode. However, when I was doing research on this, I ran across a bunch of posts saying that memory mapped mode for QUAD-SPI...
