Micro SD whith micro controller


Good morning,

This is my first post

I' m searching for a special micro SD card with:

• MCU: 32-bit (produced by ST)

• MCU clock: > 100MHz

• RAM: > 384 Kbytes

• Flash: > 768 Kbytes

• Timer function

• Random number generator function

• Secure memory area required to store encryption keys

• Flash of at least 8Gb

• Sdk to develop and Upload software on microcontroller (ex: rsa and AES key generation function)

• Password or PIN for data protection stored on the flash (not for read but only for mofify/delete/create) 

Is there anyone who can recommend me some manufacturers please?

Thank you

Hello @FuscoV and welcome to the ST Community 😊

If you are locking for an STM32 with specific characteristics. I suggest you use the MCU/MPU selector included in CubeMX:


or the ST MCU Finder. Then, using the filters you can make the choice of product.

PS: What this mean "a special micro-SD card with: MCU: 32-bit (produced by ST)"

But does it have any option for, "an STM32 on a micro-SD Card" ?

I think @FuscoV wants the STM32 embedded within the uSD card?
