I have an LM235 temperature sensor separated from the measuring device 5 meters.When an RF is induced to the LM235, it measures wrong temperatures. I have tried to minimize the problem by putting capacitors on the sensor pins but I have not obtained any results.Is there any way to reduce this problem?

I need to reball a FLI32626H that is clearly presenting soldering issues. One can see the chip is tilted with the naked eye. It has been reflowed twice to no avail.According to ST support, this is a legacy product, and ST no longer has technical resources for supporting this product. No support to legacy, that is truly a regrettable approach.So can you please inform the correct size and dimensions of soldering ball and temperature profile for this package?Here its datasheet: https://www.st.com/resource/en/data_brief/fli32626h.pdfAnd product's website: https://www.st.com/content/st_com/en/products/touch-and-display-controllers/display-controllers/fli32626h.htmlAlso, googling PBGA 409 31x31x2.46 won't return any good info...

I'm using STM32L4A6VGx , MT25QL256 NOR Flash connected with SPI. I'm trying to read the ID but didn't get any response except 0. Here is the code I wrote: // Select Pin HAL_GPIO_WritePin(Select_GPIO_Port, Select_Pin, GPIO_PIN_SET); HAL_Delay(10); HAL_GPIO_WritePin(Select_GPIO_Port, Select_Pin, GPIO_PIN_RESET); Dev_ID[0] = 0x09E; HAL_SPI_Transmit(&hspi2, Dev_ID, 1,10); HAL_SPI_Receive(&hspi2, &Dev_ID[1], 1,10); HAL_GPIO_WritePin(Select_GPIO_Port, Select_Pin, GPIO_PIN_SET);//SPI Configurationstatic void MX_SPI2_Init(void){ /* USER CODE BEGIN SPI2_Init 0 */ /* USER CODE END SPI2_Init 0 */ /* USER CODE BEGIN SPI2_Init 1 */ /* USER CODE END SPI2_Init 1 */ /* SPI2 parameter configuration*/ hspi2.Instance = SPI2; hspi2.Init.Mode = SPI_MODE_MASTER; hspi2.Init.Direction = SPI_DIRECTION_2LINES; hspi2.Init.DataSize = SPI_DATASIZE_8BIT; hspi2.Init.CLKPolarity = SPI_POLARITY_LOW; hspi2.Init.CL

I have designed an isolated AC-DC converter, 300 to 590V AC input (400V AC nom) to 24V, 4A output using the L6566-BH Controller in eDesignSuite. Attaching the details herewith.Any further guidance regarding the Design implementation in actual Hardware ?I would also like to actually design for multiple outputs for the same input: - 1) 24V, 3A 2) 5V, 3AI was not able to design this using the tool, I'm guessing it's a limitation of the tool. Would like some help in this regard also.

We are planning to use the SCLT3-8BQ7, but do not want to connect any LEDs to LDi outputs of the chip. The datasheet does not mention how to connect these pins in this case.Can you please tell us if we should leave these pins floating?NOTE: This question and answer originated from a customer support case which was handled by us. We regularly review support cases and add any helpful ones here for all to benefit from.

Hi ST,We are implementing an M24C02-DRMF3 EEPROM based design and wanted to confirm the correct package marking for this device including part number, die version, date code and fab facility. Although the Data Sheet includes the WFDFPN8 mechanical information, we are unable to find a related package marking specification on the ST site for this device.Thanks for the guidance - CC

Hi, I'm looking for what I think is a Mosfet with this print, see the attached picture.I need to replace it because it's burned, but I don't know the features.Anyone can help me about ?Thanks a lotIvano

I used to choose a 10K resistor.But something seems to been wrong. Can anybody help with this? please!

I am interested in using this part due to it's radiation tolerances. However, the datasheet posted online only explains the radiation and package specifics. There isn't anything describing the pin out and function of the part. Can someone forward it to me? Or point me to where it's located.

I am attempting to connect to an st10f276z5. I have power and ground to the device, PL0.4 tied low, and PL0.5 tied to 5V. ST10 Flasher produces a 'Bad acknowledgement value error. 0x?? instead of 0x5A' Where the read value 0x?? seems to come up different on every attempt. 0x00, 0x5E, etc.I am using ST10 Flasher v2.4b, I suspected the issue was the lack of proper monitor file. Currently I have: 001, 002, 003, 004a, 004b, 006, st10noflash, startchipidIf I'm missing the required monitor file where can I get this? If that isn't the issue what else should I be on the lookout for when setting up to connect? I have been able to successfully connect to and program several ST10F276Z5Q3 so I suspect my serial interface and wiring are correct.

I am working on a LoRaWAN and GNSS project. I have found one inconsistent operation when try to configure UART1 for GNSS connection. UART2 is used as PRINTF for logging.   Procedure to produce bug: Use I-CUBE-LRWAN example as the codebase. Add code from X-CUBE-GNSS into the project. Call GNSS_UART_Init().   Effect of bug: PRINTF() not work. UART1 is not configured.   I have tracked down to the code of HAL_UART_Init() and found that a single HAL_UART_MspInit() callback is invoked for any UART. Since the HAL_UART_MspInit() function is provided in the vcom.c so this caused the bug.  

Hi.Now I am composing the model of the device in the program Microcap using SPICE model of IGBT STGW20NC60VD. This transistor has current-voltage characteristics shown Figure 1. But SPICE model of transistor has other different characteristics (Fig. 2). So I can't simulate correctly the operation of my device, since the current can't exceed the threshold of 30 A. Please send a corrected STGW20NC60VD transistor SPICE model.

Dear Sir/Madam,I have a problem with EEPROM block erase/programming on stm8l152r8 part number.As I understood, EEPROM block erase/programming must be executed from RAM.You have a tutorial included 4 steps as I attached you its picture.I do all the steps correctly but compiler show me error in step 3 (changing linker file lnkstm8l152r8.icf).Please find attached picture of my error and steps.My condition:1-      Software: IAR Embedded Workbench for STM8 version 3.102-      Part Number: stm8l152r8Would you please help me to solving this problem?Kind Regards,Hamed

The M95M02-A125 has SO8 package. I can't see any mark or anything that shows which the pin number 1 is. I may suppose it's according to text orientation, but it's just a guess. So, the question is: how to know the right orientation of the chip?Thanks in advance.Javier

- Is the LIS331DLH long term available? For how long it will be producted?? (very important question)- Is there an evaluation bord/kit available to check the performance of LIS331DLH instead of LIS33DE??What are the main differences between this both types? BR, Andre

I'm trying stability analysis phase margin and gain margin for A6985 on the eDesignSuite.I understand that phase ​margin and fc are showed in bode plot diagram but gain margin is not displayed.and I cannot estimate it manually due to vertical axis shows less than -20dB.Do you have any idea to get a gain margin or to extend vertical axis?Thank you, Sekiguchi

Hello,I have the STM32F446RE board and would like to try out WiFi programming. I have been looking at ESP8266 but can't find a lot written about STM32 Discovery boards interfacing with the module. I understand that this module is communicated with through the UART and the AT command set. But I am concerned because all mention of the ESP8266 discuss the problem of the voltage (3.3V vs 5V). Is there any good tutorial on setting up a dev system for doing wi-fi programming.Thank you,Michael Uman

Does anybody have information on the ST Compression Utility (which says "will be part of STMicroelectronics's Faroudja QuickMatch application"). My company cannot find a 64-bit Mac OS X version - and I can't find anything on this library at all. There is no source - just header files, libs, and DLLs (or 32-bit Mac dylib).

i'm going to update my Win7-Professional to Win10; my question is :there is any knowing trouble to run Atollic TS or CubeMX on Windows 10?

I have a burned SMD Diode and I can see the ST Logo, the code LE and the date Z751 on it. Which part do I need to repair my device? Thank you.
