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.

BR,
