Hi,I'm designing a PCB that can get 8 digital inputs and 4 analog inputs. But these inputs can be range from 3.3v to 24v. For the digital inputs I have used universal logic shifter method using comparator where I can give any voltage range of digital...
I'm looking to add a serial EEPROM to a product, and have a somewhat odd situation. The device will loose power spontaneously and often (few times an hour). My question is: What happens if the M24C01-R looses power during a write operation? I assume...
Hello community,i have trouble to identify a defect power semiconductor from ST.The package is TO-220 and is marked with "GF309VW" and the ST-Logo. Can anyone identfiy the device?Thanks in advance!
Hi,The datasheet of the M95M04-DR 4-Mbit serial SPI bus EEPROM (https://www.st.com/en/memories/m95m04-dr.html) mentions on page 24 the device is implementing "Error correction code (ECC x 4)".What is the method to be impelennted on the microcontrolle...
HiI using STM6601, but my device only has only one button. I want to get a reset with a long press, but the datasheet says that the SR input cannot be connected to ground all time.Perhaps there is another way to reset?
Hello, I bought two EVLSPIN32G4-ACT motor control evaluation boards and tried to setup CAN-FD communication between them. Then I came to know it doesn't have a CAN transceiver IC(U3) populated on board. Image attached for your reference. Can anyone t...
I have the following questions and need help:1. Can this transistor be used at a frequency of 900kHz? Can it only be used in frequency bands above 1MHz?2. The data sheet provides a test circuit under 30MHz conditions. We do not fully understand the f...
since LPS22HH support one byte read or multiple byte read. wonder how LPS22HH handles the last bit on I3Cbecause last bit in Read data is 'T', rather than ACK/NACK from I3C Controller.How does LPS22HH (target) know Controller need single or mulitple ...
Hello,I'm having some problems with the M95M01 EEPROM.Firstly, I had a problem where after the writing the data to the EEPROM was not consistent with the read made afterward. I could narrow down the problem to be related to the way that I'm monitorin...
What steps are required to set stwlc98 to TX mode?If you set 0x0020 to 01, 0x000E becomes 03.However, AC1 and AC2 do not cause burst oscillation.The Optional (TX mode only) circuit is on the board, and VOUT is connected to 5V.
