 Hello,I’m working with an ST NFC tag (e.g., ST25DV) and noticed that when I add an NDEF record using the ST25 mobile apps, the system automatically adds a 4-byte Capability Container (CC) to the NDEF message record.My question is:Is there a way to append or extend the CC to 8 bytes instead of the default 4 bytes when adding an NDEF record?  

I'm trying to find a working spice model for the ST LM358. The one on the site gives an output of -12KV for a small sine wave when powered from ± 12VAnd the "contact us" email doesn't work.

Hi everyone, I'm experiencing abnormal power consumption in STOP2 mode with my custom board featuring the STM32WB5MMGH module. According to the datasheet, the power consumption in STOP2 mode should be between 2 and 3 µA. However, my board is drawing around 20 µA. After some troubleshooting, I've narrowed down the issue to the LCD module: when I disable it, the power consumption drops to the expected values. Here's my current LCD module configuration: /* USER CODE END LCD_Init 1 */ hlcd.Instance = LCD; hlcd.Init.Prescaler = LCD_PRESCALER_2; hlcd.Init.Divider = LCD_DIVIDER_27; hlcd.Init.Duty = LCD_DUTY_1_8; hlcd.Init.Bias = LCD_BIAS_1_4; hlcd.Init.VoltageSource = LCD_VOLTAGESOURCE_INTERNAL; hlcd.Init.Contrast = LCD_CONTRASTLEVEL_3; hlcd.Init.DeadTime = LCD_DEADTIME_0; hlcd.Init.PulseOnDuration = LCD_PULSEONDURATION_1; hlcd.Init.MuxSegment = LCD_MUXSEGMENT_DISABLE; hlcd.Init.BlinkMode = LCD_BLINKMODE_OFF

Hi ST Community.I am using an STM32H725IGK MCU on a custom board. My board has a uSD card slot connected to the SDIO pins, and I am using SDMMC1 peripheral. I am also using FatFS to use a filesystem on the uSD card.I can operate the SD card properly most of the time. I can mount, format, create files and folders, and read and write to files. However, sometimes, some operations fail. Normally, it's either f_write or f_lseek. They fail at the low-level disk_read() operation. I do not understand why.I will share my system configuration:- Clock MUX:- SDMMC Parameters:

Hello, I am developing a custom board with the STSPIN32G4 microcontroller.I would like to have more information about the integrated buck converter, as the documentation lacks details.What is the maximum allowed peak current? Output curent 12V :  Best regards.

Hello, I'm in the process of designing an edge computer using a MP2 processor. Due to the shortage of LPDDR4 memories, I'd like to use LPDDR4X memories. Can I use this type of DRAM for MP2 series processors? Or do you have any alternative part that I could consider for my design? Thanks in advance,Daniel

Hi Dear friends, I am trying to configure H750 to transfer data between internal SRAM and external SDRAM, I got everything setup OK but with some problems (also monitor data bus with logic analyzer). So I checked with ChatGPT, surprisingly, ChatGPT said H750 (actually it said the same thing about H74x)  does not officially support memory-to-memory transfer, ChatGPR said use MDMA instead. Before I jump into MDMA, just want to make sure what ChatGPT said is true? Thanks.

Hi,the TRM of the STM32MP257F  describes different possibilities to boot the controller including the possibility to boot from eMMC or SD-card. And when looking to the EV-board, there are DIP-switches to choose eMMC or SD-card as boot-device too.But what I can't find: how does this work exactly? How do I have to format eMMC/SD-card and what do I have to place on these devices in order to let a bare-metal application being loaded? Is there a documentation available somewhere that describes this in detail?Thanks! 

Dear STMicroelectronics Community members,I am currently evaluating STM32 microcontrollers for a project that requires strong cryptographic capabilities. Our goal is to implement hybrid encryption, meaning we need hardware support for both symmetric encryption (e.g., AES, DES/3DES) and asymmetric encryption (e.g., RSA, ECC, public key cryptography), along with hashing functions (SHA-1, SHA-2, SHA-3 if available).Specifically, I would like to request:A list of STM32 families and part numbers that include dedicated hardware accelerators for:Symmetric ciphers (AES, DES/TDES)Asymmetric ciphers (RSA, ECC, or other public key accelerators)Hash functions (SHA-1, SHA-224, SHA-256, SHA-3, etc.)Hardware Random Number Generator (TRNG)

I would like to use the STM32 Cube extensions for VSCode. I'm happily coding in VSCode for all my projects, but found the "CMake Tools" extension too limiting and therefore disabled it in favor of other CMake extensions.Unfortunately, the STM32 Cube extensions force the use of the "CMake Tools" as a dependency and are therefore unusable for my projects. Even though something like the "STM32Cube Debug STLink GDB Server" should not need to be aware of CMake at all.Would it be possible to remove the "CMake Tools" dependency from the GDB server extension, or can I somehow use it in some other way?

Split from this thread. Hello @mƎALLEm ,   Thanks for the updates. What is Bypass mode? Can you please provide guidance for this?   Thanks & Regards, Jignesh Karena  

Hello members, Until recently, I was using a G473. There, I ran code from the ccmram. That worked without any problems. Now I have switched to the H533. For performance reasons, I want to run the code in SRAM1 0x20000000 - 0x2001FFF. I want to keep the data in SRAM2. MEMORY { RAM (xrw) : ORIGIN = 0x20020000, LENGTH = 80K /*Ram placed SRAM2 with ECC-Check*/ FLASH (rx) : ORIGIN = 0x08000000, LENGTH = 256K CCMRAM (xrw) : ORIGIN = 0x20000000, LENGTH = 128K /*SRAM1 for code */ } For example, the function: __attribute__((section(“.ccmram”))) void EXTI0_IRQHandler(); is located in the map file at the correct address: .text.EXTI0_IRQHandler0x0000000020000300 0x28 ./Hal/Interface/Interrupts.o0x0000000020000300 EXTI0_IRQHandler The code is copied to SRAM1 in the startup file. However, when I call the function, a hard

I connected the nucleo board with the cpu using port CN6 using USB-C cable with BOOT0 and BOOT1 set as L and jumper jp2 is set on STLK everything as specified in getting started module in um3300-discovery-kit-with-stm32n657x0-mcu-stmicroelectronics%20(3).pdf. After this I installed tools stm32cubemx,stm32cuben6-v1-2-0 and stsw-link009. After this I used STM32CubeMX to create a new project with the following specifications: commercial part number STM32N657X0H3Q ,secure domain and PO1 as GPIO_Output in section Pinout & Configuration .In project manager I selected only Appli as project Structure with basic as Application Structure and MDK-ARM as toolchain with min version V5.32.After this I generated code and opened the project in keil uvision version 5.36. The code is building without any errors but on flashing I encounter the error Invalid ROM table. The debugger is detectable in Target. Only issue that I come accross is when I'm connecting the board using port CN6 via

Hello,I’m working with the ST25R3911 NFC reader IC in a battery-powered application where ultra-low power consumption is critical.Is it allowed to completely switch off VDD_IO while VDD is still supplied (e.g., when the device is in Wake-Up mode)?Will the interrupt pin still work in Wake-Up mode if VDD is present but VDD_IO is off?I noticed that even when VDD is off, if VDD_IO is connected, there seems to be additional leakage current. Could you clarify the expected current paths in such cases?Is there any recommended sequence for powering up/down VDD and VDD_IO to avoid unwanted currents or undefined states?Can VDD_IO be powered directly from a microcontroller GPIO pin (to save power by enabling it only when needed)? What is the typical consumption of VDD_IO in idle conditions?

Hello ST Community,I am working with the STM32U5G9ZJT6Q MCU, and I have generated the code using CubeMX for USB CDC-ACM (Communication Device Class - Abstract Control Model). The code seems to be running fine as it is entering the main loop without any errors. However, the USB CDC device is not being recognized in the Device Manager on my PC when I connect it.Configuration Details:MCU: STM32U5G9ZJT6QUSB Mode: USB_OTG_HS configured in device-only mode.Middleware: USB CDC-ACM (with SOF enabled).System Clock: 128 MHz & HSE: 16 MHZOperating System: Bare-metal (no RTOS).USB Cables: Using two separate USB cables:One for ST-LINK (for debugging and power supply).One for the application USB (for CDC communication).Issue:The application appears to run without issues (I can see it looping in main()), but the USB CDC device does not show up in the Device Manager on my PC. It se

Hi, I saw this post on the forum about 'M33 cold boot' and the possible release of the ecosystem to do so :https://community.st.com/t5/stm32-mpus-products-and-hardware/using-only-the-m33-on-the-stm32mp2-feasibility-and-peripheral/td-p/768536Is there any update about it ?If released, will it be possible for the M33 to launch the boot process of the Cortex-A and maybe power it off depending on the context ?Thanks.Regards.

Hello Together,I would like to try out the STM32CubeMonitor-RF (V2.15.0) with the NUCLEO-WBA55CG board. I downloaded the stm32cubewba mcu package (V1.7.0) and flashed the .bin file from the BLE_TransparentMode example to the board with the STMCubeProgrammer (V2.20.0)(start address: 0x08000000).When starting the STM32CubeMonitor-RF, however, the message "Device under Test not responding" appears. I then loaded the project with the STM IDE (V1.19.0) and selected the BLE_TransparentMode project for my board via the Example Selector when creating a new STM32 project.The same error message appears on the RF Monitor. Do I have to integrate the BLE stack separately?Where can I find the BLE stack?I have noticed that the loaded project structure in the IDE differs from the one from the ST Wiki for the transparent mode. The file "ll_sys_hclk_client.c" and the two libraries "LinkLayer_BLE_Full_lib.a" and "

Hi,  I'm using STM32L0 MCU, My system uses MSI as the main system clock, but my USART is to use HSI to be able to wake up from stop mode. My system will enter stop mode for power saving. I am confused about the settings, before enter stop mode, we have to set system clock after STOP mode using HAL API: __HAL_RCC_WAKEUPSTOP_CLK_CONFIG(RCC_STOP_WAKEUPCLOCK_MSI); // Set system clock as MSI after stop __HAL_RCC_WAKEUPSTOP_CLK_CONFIG(RCC_STOP_WAKEUPCLOCK_HSI); // Set system clock as HSI after stop so that USART able to wake up the MCU   void PreSleepProcessing(uint32_t *ulExpectedIdleTime) { *ulExpectedIdleTime = 0; // WFI is called within next function #ifdef TEST_LP_MODE HAL_GPIO_WritePin(GPIOB, GPIO_PIN_3, 0); #endif if (g_diableStopModeFlags == 0) { while(__HAL_UART_GET_FLAG(&huart1, USART_ISR_BUSY) == SET); /
