About STM32WBA products support EPA?
Hi all,I check with STM32WBA55 datasheet have description can supported external PA. But FW SDK(STM32Cube_FW_WBA_V1.4.0) released notes exist below description. It look Known Limitations is not support EPA, usually need logic control between FEM a...
Resolved! Use the DMAMUX with SUBGHZSPI_TX (STM32WL55 or STM32WLE)
Hello,First of all, a short text in order to present my problem :After reading all documents about the STM32WL55 and STM32WLE concerning the SubGhz and DMA, I don't find how can I use the DMA and DMAMUX with SUBGHZSPI_TX.Furthermore, I'm working on t...
Resolved! What is the output impedance of the STM32WB55?
I check the datasheet and it say that the output impedance os the STM32WB55 is 50 ohms , so i don't must need impedance matching but on the reference design have a pi-match circuit and a RF filter. Really the MCU have a 50 ohms impedance output or th...
