Resolved! STM32H7S7L8H6H XSPI instability

IssueHigher ambient temperatures cause communication malfunctions with XSPI memories.DetailsOur design is heavily adopted from STM32H7S78-DK which also has the same issue described below.The application uses memory-mapped mode for both Flash and RAM ...

stm32U585 + 2 x APS25608N OSPI - speed problems

Hai All!I use 2 pieces of APS25608N PSRAM on OSPI bus with memory mapped mode. The MCU run at 1.8V, 160MHz system clock. Previously, I used APS12808N at 80MHz and 3.3V VDD without any issues.Currently, the PSRAMs run at 50MHz, but need to speed up to...

ADC "shorting" analog input to GND

We're using the following circuit to measure a battery voltage @ 20 kHz for use in motor control.We are having some issues though, where the ADC suddenly starts measuring 0 V (0 in the data register) and gets locked in this state. In this state, we a...

Resolved! STM32H573 PB14

In our project I use STM32H573VIT6 LDO uC. We have a problem with the PB14 pin. We use 3 pins for LED control (PB10, PB13 and PB14, see photo). The problem with the PB14 is that the LED lights up dimly without code initialization. If PB14 is initiali...
