Hello,
I am now using STM32F042F6P6 for control purpose on my gate driver board. However, the ambient temperature requirement is changed to 120C compared to 85C before.
Since STM32F042F6P6 can not work under this temperature, may I ask if you could recommend a substitute for this chip which could work under 120C and has very nice compatibility with it (least amount of code need to be changed, similar register structure, input/output interfaces).
Thank you!

You probably have to get in contact with an FAE.

Hello

,You have the STM32F042F6P7 which can reach 105°C.
There are devices in other families (F4, L0, L4) designed to operate under 125°C as maximum ambient temperature.
So it depends on the features required in your application to select the ones more suitable for you.
I recommend you to use the selector from
and fix the criteria you need (like max temp = 125°C).If for example it is a requirement for you to use a TSSOP 20 package, you will have as choice STM32L011F4 and STM32L31F4.
The usage of STM32Cube will help you to easily migrate from one family to another as the APIs are almost the same.

PS: It is interesting to add a filter on temperature range in the MCU Fider tool, I will raise this request internally.

The last digit in the marking tells the temperature range; you want 3 there.
