See picture above for exact markings. No markings on the bottom of the IC.Battery powered device (low voltage)Markings:ST (e3) 7B589VA1814PHL 423Alternate version has similar markings. Maybe just a date code change?ST (e3) 7B474VA1814PHL 423
I would like to use the STM802 as a supervisor but I need to disable the watch dog intervention in certain conditions (for example firmware update).The manual says that the WDI pin cannot be left floating to block WD intervention.Is there any other w...
I need to find any info about audio IC's COBBA (4370793, 4370753, 4370837) that was used in the old Nokia phones. Maybe you could help me to find datasheets or maybe source code and models for that IC's?
Hi there! I am using STM8s for UART communication but recently I found that UART Rx does not work sometimes. I am using UART Idle interrupt for Rx at this moment. Could someone suggest a way to me for debugging?Cheers,Morris
Has anyone tried this or similar products from Microchip? Please share your experience.If not, can the drivers provided by Microchip be compatible with STM compiler?
The amount of reactive energy register is decreased while I expect it to be increased.I use a reference meter" to ensure the sign of reactive energy.what should I do?Could my stpm32 chip be fake?
Hi,Good day everyone.I am trying to setup SEMTECH SX1231 transiever to send and recieve RF packets by having SPI connection between SX1231 and STM8 controller. Its getting really hard to achieve this because of unknown configurations. Has anyone achi...
Where is the stm32 advanced nand flash driver?
