automotive certified STM32?

Hi

I am supposed to develop a 'simple' automotive project drive some interior car lights controlled by CAN.

Which ST controller is best suited for this? (Cheapest and smallest)

Are any of the STM32 certified for automotive ?Is there a ST controller with built in CAN interface?Does ST have a certified CAN protocol stack?If not which one would you recommend?

Thx

Would also be interested in a +125C rated part, even at reduced spec, a lot of applications/locations where +85C won't suffice.

What is the constraining factor here? FLASH? Programming/retention?

+125C

There are a few mentioned, look for

3 = Industrial temperature range, - 40 to 125 °C

suffix. I don't know how hard it may be to chase them down in the wild.

Ok, mostly seen 6 (Commercial) and 7 (Industrial) suffix devices

ST might want to pull this into their IoT focus, while Car/Automotive might be the primary internal driver, the use of stuff above 85C gets to be important deploying IoT devices into inhospitable environments, where direct sunlight and ambient temperature are high, and cooling is not available/practical.

Mouser is pulling up an odd mix of STM32L0 and L4 device (notably L496, L475)

I3 and T3 suffixed parts

http://www.mouser.com/Semiconductors/Embedded-Processors-Controllers/Microcontrollers-MCU/ARM-Microcontrollers-MCU/_/N-a85pc?P=1z0wuod&Keyword=stm32&FS=True

 

Poorly categorized in Mouser, no F4 explicitly found at 125C, found looking at the auto-complete suggestions in the part search box (ie looked for 3 suffix as typing STM32F4..)

ST's Data Sheet is out of date, doesn't describe 125C part

I am not sure whether this is 🙂 or :(

Also, sticking to ST, there are two dedicated Automotive lines in the STM8s, and also 3-suffixed parts in the non-automotive lines.

And they are available now, e.g.

  (with CAN as per OP).

Hello,

There is no STM32 with automotive qualification. Automotive qualification is much more than just the temperature...

There are 125C temperature version in the following families:

- STM32F4 access line (STM32F401, STM32F410, STM32F411, STM32F413, STM32F423)

- most STM32L0

- most STM32L4 

complete list

http://www.st.com/content/st_com/en/products/microcontrollers/stm32-32-bit-arm-cortex-mcus.html?querycriteria=productId=SC1169$$962=125|125

STM8AL and STM8AF are qualified for automotive.

There are 125C and even 150C versions available.

STM8AF52xx have a CAN interface and certified driver can be purchased from vector software.

Best regards,

Max

I have used the same filter on that table. Sadly, it does not indicate real availability at the ''garage-scale'' distributors.

And not only that:

I understand why, it's just that it's again misleading and does not help in searching.

I don't try the ''selector'', as I won't install Java (wonder why would that need to be so).

Hi Jan,

The selector is behaving in a way that it marks a line as active as soon as at least one given device belonging to this line is active.

This is the case for STM32F413RG.

Hi Amel,

Thanks. As I wrote above, I understand why is it so; I just said it may be confusing.
