Trusted platform module (TPM) either integrated in to the microcontroller..? or additional module to enable the device level security (TBD).

Is STM32WB55REV6 has Trusted platform module (TPM) either integrated in to the microcontroller..? or additional module to enable the device level security (TBD).

Can you please help me on the ablove

Hi @na.1​ ,

TPM is not a good choice for a microcontroller security - it's quite an overkill, as it's intended for application platforms like PC. I think you should consider rather https://www.st.com/en/secure-mcus/stsafe-a110.html

Hi JHOUD,

Thanks for your response can you please share details about the application of the STSAFE-A110 with the STM32WB55REV6 i mean data regarding interfacing details, design schematic, application notes.

Hi @na.1​ ,

I'm afraid there is nothing specific available for this particular setup (WB+STSAFE). But the interfacing is easy, with I2C fast mode bus and well documented interface. Existing implementation is for example https://www.st.com/content/st_com/en/products/evaluation-tools/product-evaluation-tools/mcu-mpu-eval-tools/stm32-mcu-mpu-eval-tools/stm32-discovery-kits/b-l4s5i-iot01a.html

Given the similarities between L4 and WB you should have no problem adjusting the examples to your project.
