Hello ST Support Team, I’m currently designing a custom board using STM32H750XBH6.In this design, I would like to interface a 32-bit SDRAM for improved memory bandwidth and performance. However, I noticed that in the official STM32H750 development bo...
Hello,I want to change for boot to use XSPI1 interface, but I am not sure about OTP bits, there in description some bits is not very clear, what OTP bits to set to switch if it's possible ?Additionally if I will use SD card for boot I can set OTP11 v...
Honestly, this choice feels like a trap.STM keeps promoting it as a “solution,” but compared to Murata, ESP32, or Broadcom it looks outdated:– Legacy M4 core, original MXCHIP code from 2017– Closed software, very little documentation– Hard to debug (...
I have a NUCLEO-C071RB with an STM32C071RB. In section 31.1 of RM0490 Rev 5, it describes the first 32 bits of the unique ID like this:Bits 31:0 UID[31:0]: X and Y coordinates on the wafer expressed in BCD formatBCD should mean binary-coded decimal,...
Good Evening Sir/Mam, Sir/Mam, I have a query about the DCMI of STM32U595RJT6Q. I have read the Datasheet of STM32U595xxx and it was written in it that- DCMI of this MCU is for use with Black & White Camera Modules and it is assumed that all preproce...
Hi everyone,I’m currently designing a board using an STM32H533RET6 and I have a question regarding the VSSA pin connection.Should VSSA be tied directly to GND (VSS) like the other ground pins, or should there be an inductor (L) placed between VSSA an...
DS13565 Rev 2 says under 3.20: "The embedded USB controller cannot be used on STM32G0B0KE as this device does not provide an HSE oscillator input.". Well, sounds reasonable. But same DS says in Table 11 for Pin 2 (LQFP32) PC14: "OSC32_IN, OSC_IN" whe...
Hi everyone, I'm using an STM32H755 microcontroller to read 20 temperature sensors (NTC thermistors) via 20 ADC channels for a testing setup. Each thermistor is wired in a simple voltage divider circuit like this: [VCC] -- [NTC] --+-- [Fixed Resistor...
The ref manual (RM0481 page 2585) says: "This circuit has a defined startup time (tSTARTUP specified in the datasheet) during which the behavior of the USB transceiver is not defined.". I searched for USB and tSTARTUP but could not find anything in t...
Referring to RM0444 and DS12232 (referring to STM32G0x1 programming manual and data sheet).In the Low Power section, the RM states that there are five wakeup pins:But in the register section, there is clear mention of WKUP3 (EWUP3 bit in PWR->CR3, WP...
