Others: hardware and software

I am interesting in using the HCC4051B multiplexer in my design. However, I can't seem to find a good datasheet that describes the pin outs, and functionality.

I am interested in using this part due to it's radiation tolerances. However, the datasheet posted online only explains the radiation and package specifics. There isn't anything describing the pin out and function of the part. Can someone forward ...

I just received a notification that LSM303CTR is Obsolete, do you have a replacement to suggest.

ST10F276Z5 - ST10 Flasher: "Bad acknowledgment value"

I am attempting to connect to an st10f276z5. I have power and ground to the device, PL0.4 tied low, and PL0.5 tied to 5V. ST10 Flasher produces a 'Bad acknowledgement value error. 0x?? instead of 0x5A' Where the read value 0x?? seems to come up diffe...

HAL_UART_Init() bug for more than one UART setting

I am working on a LoRaWAN and GNSS project. I have found one inconsistent operation when try to configure UART1 for GNSS connection. UART2 is used as PRINTF for logging.   Procedure to produce bug: Use I-CUBE-LRWAN example as the codebase.Add code fr...

Invalid SPICE model IGBT STGW20NC60VD.

Hi.Now I am composing the model of the device in the program Microcap using SPICE model of IGBT STGW20NC60VD. This transistor has current-voltage characteristics shown Figure 1. But SPICE model of transistor has other different characteristics (Fig. ...

How to know which is the pin #1 of a M95M02-A125?

The M95M02-A125 has SO8 package. I can't see any mark or anything that shows which the pin number 1 is. I may suppose it's according to text orientation, but it's just a guess. So, the question is: how to know the right orientation of the chip?Thanks...

Hello, the accelerometer LIS33DE is obsolete. Now we may want to implement the LIS331DLH. But I have some questions:

- Is the LIS331DLH long term available? For how long it will be producted?? (very important question)- Is there an evaluation bord/kit available to check the performance of LIS331DLH instead of LIS33DE??What are the main differences between this both...

Stability analysis for A6985

I'm trying stability analysis phase margin and gain margin for A6985 on the eDesignSuite.I understand that phase ​margin and fc are showed in bode plot diagram but gain margin is not displayed.and I cannot estimate it manually due to vertical axis sh...
