I see that ST2100 is active but it seems there is no stock in anywhere.I only see datasheet but, are there more documentation, application note, evaluation board for this broadband PLC Soc?Thanks in advance!.Best regards.Francisco Jimenez.

Hello, I've downloaded the provided .lib file for p/n STD13N60M2 and created a part for it in LTSpice, but am not having any luck getting it to work correctly. I've created a circuit with a half bridge and get the expected results when using the model included with LTSpice for STM p/n STW11NM80, but no luck with the part I'm hoping to use in my design.I've mapped the pins from the .subckt line in the .lib file as follows:Any suggestions or nuances I'm missing to get this model to work correctly?

Hello,I currently work with an STM32L496ZG chip and the EEPROM emulation driver (download on https://www.st.com/en/embedded-software/x-cube-eeprom.html).In the "eeprom_emul.h" file, we have the next macro :#define PAGE_ADDRESS(__PAGE__) (uint32_t)(FLASH_BASE + (__PAGE__) * PAGE_SIZE + ((START_PAGE_ADDRESS - FLASH_BASE) / BANK_SIZE) * BANK_SIZE) /*!< Get page address from page index */ #define PAGE(__ADDRESS__) (uint32_t)((((__ADDRESS__) - FLASH_BASE) % BANK_SIZE) / FLASH_PAGE_SIZE) /*!< Get page index from page address */ #define PREVIOUS_PAGE(__PAGE__) (uint32_t)((((__PAGE__) - START_PAGE - 1U + PAGES_NUMBER) % PAGES_NUMBER) + START_PAGE) /*!< Get page index of previous page, among circular page list */ #define FOLLOWING_PAGE(__PAGE__) (uint32_t)((((__PAGE__) - START_PAGE + 1U) % PAGES_NUMBER) + START_PAGE) /*!< Get page index of following page, among circular page list */It is use by "eprom_emul.c" for these functions (Init, CleanUP, Read...).I need to change the address

Hi, I use CLT01-38SQ7. In datasheet (DocID028182 Rev 1) is not clear to me how to use Vcs pin (24V sensor power supply sensing input) for UVA purpose.In Figure 7. “Logic status of the SCLT3-8BQ7 power supply�? voltage ranges of Vcc and Vc are shown, but I do not understand how these values are determined, since they depend on the values of the voltage divider in the circuit Vcs (pin 14) and his input current.                                   NOTE: This question and answer originated from a customer support case which was handled by us.

We are using USBUF01W6 as EMI filter for STM32F207VCT6 in USB D+ and D- lines in Full speed mode and we have connected VBUS (5V) at pin 3.3V pin of USBUF01W6. Does this make sense to you?NOTE: This question and answer originated from a customer support case which was handled by us.

I have to read this ARM926 by JTAG connections but I don't have MCU pinout. On web I can only find a datasheet without pinout description.

Hello...Is the STG3157 suitable for headphone-level audio? I need to switch between the inputs of two microphones and put one of them into a small audio amp IC.Thanks!--Jim Newton

Hi, I have searched and could not find any information about the Accordo5 nor Accordo2 SOC in the entire community. Even the Accordo5 product page do not contain much information. I am at loss to where to get information about the complete tool chain for the SOC development. Anyone can help to point me to the right direction/link?

Actually i have many Ic's bought from Texas Instruments,ST,Analog Devices etc.And i have to evaluate my circuit before making it into design.So please help me in selecting a good simualtor with all recent devices and ics libraries available with it.

To reproduce Load GetPos or SimOSGetPos app with STM32L073 example. Enable I2C in gnss_app_cfg.h #define configUSE_I2C 1 Firmware prints out "Booting", then no result. Try to debug by setting a breakpoint at the buffer reading code in TeseoConsumerTask() function (main.c). Stop only just once and never again. gnssMsg = GNSS_Get_Buffer(&pGNSS); UART default setting works fine.

To reproduceEnable I2C in gnss_app_cfg.h#define configUSE_I2C 1When moved, the UART log said(11:58:08.056) -->�?�Going�?�to�?�run...(11:58:12.943) Can�?�not�?�read�?�axes(11:58:12.963) >>�?�sensor_event(11:58:15.875) Accelerometer�?�NOT�?�initializedEverything is ok for default UART setting. One possible issue is the configuration of I2C1 in interrupt mode for Teseo component with background reading.

I can't find any information about VN380SP at the st.com siteIs VN380SP discontinued? Deprecated product?

I was planning to use STP15N95K5, for one of the power converter application. I have RMS current for the switch around 4 A with repetitive peak currents around 30A (0.2 duty cycle with a frequency of operation of 140kHz). The switch operates at a DC voltage of 650V.I am very confused about calculating the peak current. Whether the switch is capable of operating at the specified conditions. Can you please let me know if it is possible to use this particular switch with the calculations?

does anyone know if this chip 23257-B is a variant of ST72324 8-Bit microcontroller? I am looking for a datasheet to confirm, thanks!

I am trying to identify this 32 pin chip (23257-B) used in an automotive application (see picture). I am unable to locate any spec sheets. I am pretty sure it is a variant of the STMicroelectronics ST72324 8-bit microcontroller.  Can anyone confirm and provide a spec sheet for the 23257-B? Thanks - Dana

I'm using the SPW04SA module and want to write sensor data to the Azure Storage Table service. To achieve this I have to add special headers to my requests.Until now I couldn't find out if/how this can be done using AT+S.HTTPPOST and AT+S.HTTPGET. As I understand the documentation I can use the files <in_filename> and <out_filename> to achieve this. However I couldn't find an advice, in which format the 'Custom http request" must be present in <out_filename>. (By the way: For the HTTPGET command the meaning of <in_filename> and <out_filename> seems to be swapped. The response body can be found in <in_filename>)

I want to communicate with the wifi module integrated in the STM32 iot node using AT commands, so i configure the internal uart3 used by the module to receive AT commands and transmit the answer to the AT command but it doesn't work ?

Does anybody have this L9678P typical circuit​ and could you explain the component select method and IC pin function?

I used spice model downloaded from ST product page. But model behaviour is highly strange in LTspice XVII. There is 60V Gate voltage in I. and IV. quandrant. Negative gate current turn triac ON only in one quadrant.Is it possible to use ST models in LTspice? Or does exist some model for LTspice?Thaks a lot.Jan

I am trying to see if a chip marked "23257-B 1MU2114" is a predecessor to the ST72324 8 Bit MCU. It is used in an automotive application, and the documentation says the chip on the board should be an ST72324, but the "23257-B" is there instead (see picture). Does anyone know what the 23257-B is? Can't seem to find data sheet on it anywhere. Please advise - thanks - Dana 

Hi ST10F276 group,we have used St10F276 many years. It works very well. But one project generated random NMI trap recently, and crashed the application. My question is how I can back to user application from NMI trap (interrupt)? So far I only can do is RESET (reboot) the application.Thanks.

I'm using the SPWF04SA module to write sensor data to Azure Storage Table service by sending https POST request over a socket connection. The application works fine for some hundred requests over several hours but occasionally a WIND: NtpServerDelivery message just occurs when I have opened the socket for writing which makes my program hang (yet unknown reason).To circumvent this problem I wanted to control the SPWF04SA ntp client so that the WIND: NtpServerDelivery messages occur at a time where I'm just not opening a socket.I can switch off the NtpServerDelivery with AT+S.SCFG (ip_ntp_startup = 0) command but I'couldn't manage to change the refresh interval with AT+S.SCFG (ip_ntp_refresh = xxxx). Whatever value I write to the 'ip_ntp_refresh' variable (success controlled by reading it back), the WIND: 'NtpServerDelivery' events comes in every 60 minutes.Is there something I could be doing wrong?Is there a way to control the timing of the WIND: NtpServerDelivery messages?

I want to #know if I can #create Topics with #hashtags. And further if I say whodunnit.io does it turn into dummy hotlink?
