Hello everyone, I use MCU that has 3V3 output and 5V input tolerant pins, but for my application I need to have 5V output and 5V tolerant input pins. How can I achieve this? Expander is not in the option because it needs SPI/I2C drivers in firmware, and I want to avoid that. I can make 3V3 pin output into 5V pin output using MOSFETs but then the input part is tricky.
Thanks in advance !
Hi Infineon team,
In some of our designs we use the SAK-C167CR-LM-HA+ microcontroller. Can we use SAF- C167CR-LM in place of it?
Are SAK-C167CR-LM-HA+ and SAF- C167CR-LM functionally equivalent? On page 59 of the datasheet, I can see that ambient temperature rating is different between SAK and SAF prefixes. Other than this are there any differences? What does the "HA+" stand for?
Thank you.
Regards,
Abhijeet B

Do we have System Tick timers for S6J3370 Controllers
Hi Experts ,
Can you check and advise the marking format in spansion NOR flashing products ? It refer to any lot code or something ??
MPN : S29GL128P10FFI010
Any PCN and changes in the products due to the infineon and spansion meger .
Pls advise and looking forward for your support.
Thank you
Regards

Hi Sir,
We are using this IC (ICE5GR2280AGXUMA1) for dual output isolation. The primary side is 12V 2A, and the secondary side is 12V 2A. However, when we tested both sides at 0.8A, the voltage dipped to around 9V. This IC has a maximum power rating of 24W. Can we increase the IC power rating, or is this IC sufficient?
Currently we are using this transformer specification i attached below.

We use an Infineon FP 420 L 90 B magneto-resitive sensor to sense position in a precision tilt mechanism, but Infineon no longer makes this part. Does anyone know of a replacement part made by Infineon or another vendor that could take the place of this device?

Can anyone please explain the meaning/root cause of "Clock stop wait timeout reset" reset cause.
Thanks!
Hello, we have used hundreds of thousands of the PMA7107XUMA1 in our products since 2013. I did a LTB through Avnet and on that LTB i have received 3 DC's 1818, 1026 and 1112. I have contacted Counterfeit@ Infineon and confirmed with Avnet that these are good parts. DC 1818 works perfectly. 1112 we cannot program. 1026 we can program yet fails test. 1818 can program and pass test.
We have on hand 1806 DC and we can also program and test. We use an Abracon ABM8-18.08 crystal that we have used for years. Thoughts on 1026y and 1112?
