Resolved! Help identifying this ST op amp
I need help identifying a particular ST SOIC 8 op amp. It has the markings: 204/ 9125 I hope to hear back from you as I am interested in this op amp but I cannot find out what it is.
Resolved! VN05NSP Replacement
Hi All, Looking to see if there are any replacements for the VN05NSP. Attached is the datasheet for it. I found VN5E006ASP-E but am not sure if it could work. Attached is it's datasheet as well. Thanks for any help. Byron
Resolved! Blue Pill UART communication problem: bytes not received in loopback test
We are interfacing a Chafon MU910-M UHF RFID reader module with an STM32F103C8T6 (Blue Pill) board using UART communication. During loopback testing, we observed that individual UART ports are functional and can transmit single byte, but when attempt...
Resolved! EVLSTGAP3SXS-H circuit question
Hi,Im analyzing the circuit of the STGAP3SXS in EVLSTGAP3SXS-.I want to ask what's the purpose of this capacitance in the soft off pin, I thought it was filtering by why does it go to the VL instead of GND_ISOThank you.
st33ktpm2x dts file
Hello,We are testing the st33ktpm2x as a secure key generator and storage on our raspberry cm4 running openwrt (kernel 6.6), but came across some problems when trying to access the device.When we connect it via the i2c1 and use the dtbo provided from...
Safe Operating Voltage for STHV800 in Fault Scenarios
Greetings Community,I am using the STHV800 ultrasound pulser in the analog front-end of an ultrasound imaging application. In my setup, I pulse at ±50V, generating a 3-cycle biphasic signal at 5.2 MHz for transmit. The transducer is connected via a 2...
Resolved! STR73x: CAN behavior in loopback mode
STR73xx MCU's are old, but I think the CAN operation is similar to newer parts. This part supports loopback and loopback with silent options. I am interested in the one called just 'loopback'. In loopback, the TX pin is active, but RX pin is disconne...
Resolved! need help setting CAN Rx acceptance mask and filter on a (old) STR73x processor, copied this from the STM32 MCUs Products forum
I read the CAN section of the RM0001 Reference manuaI STR73x ARMTDMI microcontroller family a few times, but still don't understand how to set acceptance masking and filtering. I want to only accept CAN extended messages with 29 bit headers that matc...
Stepper motor drive EMI Filtering
Hi everybody, I am kindly new to the EMI requirement field. I am currently designing a stepper motor control board based on a L6470 driver. I have strict EMI standards to meet so I am thinking about filtering the noise and perturbations caused by the...
