Part Number: MAX3232
Dear Team,
I am facing issue while using the Chipset from the Texas Instrumentation.
Currently, I am using MAX3232IPWR (2/2 Transceiver Full RS232 16-TSSOP) For one of my projects.
While using this IC I have observed that the IC is not providing proper response and send some garbage data because of which my communication system is not getting up and I am not able to make my product run.
Below is the output of the IC.
Here C10005 is a TX command and I can expect R10005 as a response but, I am not getting this response with the currently used IC.
*********************************************************************
I had ordered same IC sometimes ago and those ICs are working well in more than 100 boards.
I have checked the Old IC with the same Firmware and I does get proper response as you can see in below image.
**********************************************************************
Upon debugging I have observed that the both the IC have different part number printed on it.
The one which is not responding properly having a part no. :MB3232I 08K G4 A8GT
The old one which is responding properly having part no. : MB3232I 18K G4 A2KR.
Can you please let me know the difference between these two ICs part numbers printed on it and what does it indicates to?
Thanks,
Jay Patel
