I was looking at the database and I did not find this component. I would like to ask help to identify it because I believe that is a discontinued product and may be I am not looking in the right database. Can you help me? I attached the image:

Hello I have another question     I am currently working on a microcontroller project I am building a GPS tachometer which transfers the NMEA data of the GNSS 4 Click Module from Mikroe via UART to my STM32L052K6T6 and outputs it to a display   How can I use a specific sentence from a set of NMEA data sets to output to a display? in my application I need the GPVTG data set, can I simply compare the strings or how can I best solve.   My existing code you can find below

Current data sheet says "When not connected (left floating), these inputs are read as low (0).",​But old Datasheet (REV5.0) says "Chip Enable (E0, E1, E2). These input signals are used to set the value that is to be looked for onthe three least significant bits (b3, b2, b1) of the 7bit Device Select Code. These inputs must be tied to VCC or VSS, to establish the Device Select Code."​Which is correct, including the old device?They have an internal pull-down?​​Best regards.​

Hi guys!I just have a question if STMs MCU's are capable of doing somethings that I need.Currently I have a project that integrates an ESP8266 for the SPIFF (File System) and a Wi-Fi module for a Webserver. I really dont want to keep using the ESP8266 and move onto a mcu that I am more familiar with.I did some research but couldn't find concrete evidence that the STM can replace the ESP8266.So I am asking here if the STM MCU is capable of: Can a STM MCU provide a filesystem within its flash memory? If not what do I need to do to get a File System within a STM MCUCan a STM MCU provide a webserver? I read something about LWip but didn't say practically it supports webservers. Would I need a STM that has a built in Ethernet controller? etcAny tips are helpful thanks TLDR; I need to replace an ESP8266 for a STM mcu but needs a file system and Webserver/Http Server

Hello, I would like to read and write an ST90402C6 mcuand i own a jegger flasher 5 but i cant choose this mcu model. I can select only ST92F120ST92F124 ST92F150ST92F250.If anyone knows of any other way to be able to read this chip?Thank you

I assume that a date code 99 chipset is way past its "Best By:" date. Just curious as I have seen this before but never asked the question.

Hello,I'm repairing SICK sensor and found the unknown component. Please help me recognize this part and possible replacement part.Thank you.

We need the Material declaration of BAT54ZFILM, obsolute product.Please send it. ​

How do we increase the voltage obtained as a result of the current measured in x-nucleo ika-01a1

Hi,This is the first time I am asking on this forum.Could you please help me with Some design help.I have designed circuit with eDESIGNSUITE for following requirements.1.Input voltage:180-265VAC2.Output Voltage-17V 4.2Afrom the design, it resulted out transformer primary inductance:1.6mH.I am bit surprised with the value, because I have checked another similar Design, they have very less inductance.Could you please help me that "Can we trust on eDESIGNSUITE?This is the first time that I am designing with Stm tools.Please help.​

Good morning all. I hope you are well.My quest is for the VND600-SPI am using this power switch for the LED drive.I drive LEDs using the Pwm signal for dimming the power of the leds. I use 1 khz frenquence input f the vnd600-spProblems arise in this situation. The VND600-sp gets very hot.About 90 centergrad. Is this temperature normal? or this power switch is not compatible with using pwm.I am waiting for your answer.Sincerely thank you

I can't find any forum for the Teseo so I'm asking here. I need to know if it's appropriate for a very sensitive receiver in the sub-200MHz range. If the module contains any DC/DC switches that raise the noise floor in these frequencies then it's a non-starter for my project.Furthermore, because of the mechanical size constraints, proximity of the module to the RX chain of the circuit is non negotiable, so I can't just redo the layout to move it away.

Hello. I going to use MLPF-WB55-02E3 with STM32WB55V WLCSP_100.1 On the datasheet MLPF-WB55-02E3 there are recommendation for PCB assembly this chip. The document prescribes to use ground CPW line (on antenna side) with sizes as in the pictures Figure 13. and Figure 14 .  The chip MLPF-WB55-02E3 has 50 Ω nominal impedance . I calculated the ground CPW line with sizes as Figure 13, 14 and got a different value (not 50 Ω ). See the attachment: Did I make a mistake?What  impedance should the line have?Can I make the line according to my PCB stack?2 On the Figure 13 there is a line from STM32 RF port to input MLPF-WB55-02E3. The line has some sizes. Is the sizes part of the mattching design? What is this line characteristic?Can I make the line according to my PCB stack?

Hi,I'm trying to develop using the M24M01 product. There is a part in DATASHEET that I don't understand, so I leave a question.In the item 'Maximum Rbus value versus bus parasitic capacitance Cbus', it is stated that the Rbus X Cbus value should come into the below time line. But if the cbus value or rbus value is too small,(ex. Rbus X Cbus = 10ns for 1kohm, 10pF) What could be the problem? In addition, a pull-up resistor is not required on the SCL line? (Not in DATASHEET)

I need the most recent version of the SPEAr USB Flashing utility that works with SPEAr1340. Version 3.2.5 is listed on st.com but the download is decidedly not the USB flasher. The previous version download, v2.4, does download but doesn't work with the setup I have. Is there a way to get version 3.2.5 or newer?

How to know the of manufacture of this kind of ICs, since it is not written in the datasheet ​

Can the M95M01 work in half duplex mode? The Master has a 3 wire SPI interface with one open drain DIO. From the timings it looks like the M95M01 output is in high impedance whenever the master is accessing the bus. When the slave is answering the master should be recessive. This seems to work, so that there will never be a conflict/short condition. Do you agree?

Hi,Currently, I have two boards that contain a 5 volt power supply. Due to flexibility for future projects, both of are powering the same pin on a connector. The STMPS2171STR was added to one of the boards to cut the voltage going to the connector. However, during bring up I checked the impedance of the output pin of the STMPS2171 to ground and it was high, this matched the datasheet. Once the board was powered on (enable off), I noticed that I had current flowing into the STMPS2171STR , when measured and it was roughly 10mA. I decided to recheck the resistance to ground and surprisingly enough I had 1kOhm to ground. I turned off my power supply and the impedance stayed roughly the same. This behavior goes against what section 3.4 of the datasheet.I have a few questions about this component.I am using this IC correctly?I tested a total of 3 different boards, and all of them display a similar behavior. However, the boards were build by hand, How resistant to heat are those ICs?The datas

Hi,the included data brief in ST site does not provide the function of input pins. Like a truth table as to how to control different channels I was wondering if someone can provide me with the same..Thanks in Advance.Thanks and Regards,Siva

hey allI am using EEPROM library in the link belowhttps://github.com/sinadarvi/SD_HAL_AT24/blob/master/at24_hal_i2c.cI used the code successfully and it worked properly. I am using AT24C32. there is a WriteProtection pin on it, without enabling it, the library worked, do I still need to worry about WP pin?
