Please suggest a SIL2 Certified 32-bit Micro Controller.

[NRedd.3]

We are working on Redesign activity of a PLC System; In that we have to Replace Micro controller. Could you please suggest a Low-cost and Sil2 Certified 8,32-bit Micro controller .

Requirement:

1.SIL2 Certified controller

2.48 or More Pin's, SPI Interface - 01 + 01(Optional)

3. SIL Related libraries should be support

4.1K bytes of ram, 1K bytes of eeprom and 12k of on-chip rom(Minimum).

5. Clock frequency >3 MHz

6. Operating Temperature -40°C to +85°C

7. Operating Voltage 3V to 5.5V

Please let me know if you have any questions.

Dear @NRedd.3​ ,

Commonly we have no HW product certified for SIL but we provide certified FW libraries performing self-test of generic parts of the microcontroller together with wide set of documentation helping to setup correct process at STM side. Today most of the common STM32 products are supported by this FW packages. Please visit

https://www.st.com/en/embedded-software/x-cube-stl.html

for more details. From this point of view, you are not limited to concrete product. Then you can visit

Microcontrollers (MCU) and Microprocessors (MPU) - STMicroelectronics

and choose one of the Arm Cortex MCU ranges suitable for you, run product selector and apply filters on the pages there to find a proper product for you.

I suggest you focusing brand-new low-cost mainstream member - STM32C0 subfamily replacing previous 8-bit devices.
