Hello Im looking for an old datasheet for the coil driver used In automotive application VB016I have find some VB0xx series’s datasheet for others models of coil drivers but not mineIf anyone have it or know where I can find.. :)thanks mickael 

I found a conflict in the datasheet of PD57060. Or I understand it wrong. Could any of you kindly clarifying the confusion for me.In datasheet page 4, the gain is about 14.3db when the device operated at 945Mhz. In datasheet page 12, the |S21| magnitude is 0.38 at 950Mhz. If I use the formula Gain=20Log10(0.38) to calculate its gain at 950Mhz, it's -8.404db.  Why the result is so different? -8.404db vs 14.3db? which number should be trusted?Thank you

Hi,I would like to know which type of this company's SiC MOSFET product has multiple bonding wires and the case can be opened by chemical etching. I would like it to be a single chip and not a module.Can anyone give me some advice on this please? Thanks in advance for any replies.Best regards,Tianqi

I'm trying to interface the M24256E-FMN6TP I2C EEPROM IC. So far I'm able to write and read data from the memory area. However I'm not able to access the Identification Page and Configurable device address (CDA) register.Apparently the model I have is shipped with the CDA register set to 0000_0000b, thus the device address is 000b. Checking the datasheet, when addressing the EEPROM it is also required to specify the Device Type Identifier which has to be set to 1010b for memory access and 1011b for accessing the Identification Page and the CDA register. Accessing the memory area is fine for read and write (taking in to account that for writing the WC pin needs to be low), for example:  [1010_0000] [ACK] [MSB_ADDR] [ACK] [LSB_ADDR] [ACK] [Data_in/out] [ACK] ...  But when I try to access the Identification Page or the CDA register I get a NACK after the first byte:  [1011_0000] [NACK]   The EEPROM is usable even withou

I am using M24256-BW M24256-BR M24256-BFM24256-DR M24256-DF 256 K-Bit I2C EEPROM for booting purpose.While writing the data into EEPROM, I am not able to write the last byte(64th) of the page.If I will write it separately, then it will work fine but with the page write it is not. Is there any workaround for this issue.I am following the correct sequence of steps given in the datsheet.Thank you.  

Hello,I am planning to drive 3 Stepper motors using ST drivers. Currently, I would like to use L6470 for 2 motors and L6480 for the remaining one. I am planning to develop a test setup using following EVAL boards from ST, X-NUCLEO-IHM02A1 - Drive 2 stepper motorsEVAL6480H - Drive 1 stepper motorSTM32 Nucleo Board - TBDCan I use a single Nucleo board and daisy chain the SPI controls for both the motor boards? Can you suggest a Nucleo board for this configuration?Thanks. 

I am using the GNSS receiver STA8100GA and the EVAL board EVB-TAPP_E1. Yesterday I wanted to change the protocol from RTCM to NMEA. To do this I used the FW configuration window to set RTCM_OB_OFF_SWITCH = 0 & RTCM3_ON_OFF_SWITCH = 0 and NMEA_OVER_UART_ON_OFF to 1 and NMEA_UART_PORT_NUMBER to port0.After applying the new configuration and reconnecting the device, Teseo Suite can't detect my receiver.The receiver is also not detected when I add it manually with all possible configurations. So I think I've done something wrong.  Is there a way to flash the default firmware without Teseo Suite (because I can't find the device in the FW configuration panel)? 

Hello ST,How to check ST Manufactured Ics Mnfg date, Production details, Production Longativity, etc.Thanks SK_20  

Dear Mr/Mrs,I would like to know the following characteristic of the M24256-DRMN3TP/K component:TjmaxThermal Rj-cThermal Rj-bThanks in advance,Best regards,Carlos

in ISO808 I have connected +5V at VDD and +28V at VCC. In my application isolation is not required so is it ok if I short GNDDD and GNDCC with filter?

LSM9DS1 provides 3 orientation registers (ORIENT_CFG_G), but I need Euler angles instead and conversion algorithms require four orientation values. Could you help?

I'm trying to clone the ST example project ...\ST\BlueNRG-LP_LPS DK 1.4.0\Projects\BLE_Examples\BLE_SensorDemo_StaticStack as the starting point for my new WiSE Studio project.  But not having luck at the build phase.  I'm sure it something simple I'm overlooking. These are the steps I'm doing...1. In WiSE I select "Create a project", C Project, Enter project name "FooBar", Executable/WiSE Project, Debug & Release, Board "steval-idb012v1" and hit Finish.  Project gets created OK.2. Right click project FooBar in Project Explorer and select Import.3. Select General/File System -> Next  (Maybe I should be selecting a differntn choice here?)4. From Directory "...\ST\BlueNRG-LP_LPS DK 1.4.0\Projects\BLE_Examples\BLE_SensorDemo_StaticStack\WiSE-Studio\STEVAL-IDB012V1"5. Select "STEVAL-IDB012V1" from left hand pane.  Four files in left hand pane automatically selected (.cproject, .project, BLE_SensorDemo_StaticStack.elf.cfg.6. Select Into Folder "FooBar". 

Hi,Is there any library for which i can give the data from GNSS (Global Navigation and Satellite System) as input to the Library.Thank you.

Hi, I would like to download older versions of the VL53L5CX gesture library (to be exact the 1.7 and 1.8 versions for cortex M4), but I'm only allowed to download the latest one (1.9). Is there any possibility to download these two versions?Regards.Stepan

The below mentioned parts are failing for the ISO 7637-2 Pulse 5a and 5b. I have attached the image of the simulation result which we have done for the ISO 7637-2 pulse 5a in that the maximum power is went beyond the rated power of SM6T39CAY TVS diode(SM6T39CAY).1.) SM6T39CAYWe need the suggestion from the STM Microelectronics for the alternate TVS diode which need to be compliant for the below mentioned ISO 7637-2 standard. The ISO 7637-2 Pulse 5a and Pulse 5b is our critical requirement. The below mentioned standards are our design requirements.Pulse 1Pulse 2Pulse 3a and Pulse 3bPulse 4Pulse 5a and 5b 

HiI need to modify many of the paths in the "project/c++/mcu gcc path". Is there a way to export/import the paths.Or are the paths in stored in a file so that i can edit that file directly ?I am trying to avoid to modify the paths one by one.The objective is to keep all the system headers and middleware in a folder that all other projects can access to save memory. And I need to modify the paths in the projects to locate those system headers. thanks

Hello everybody!Wish y´all a good day, i´m considering to use the STRKT01 for a project but before i buy it i need to know the physical dimensions of the module/development card, also the dimensions of the case that the kit includes. Thanks!
