Can two ATSHA204As generate the same sequence of random numbers using the same seed? I passed through ATSHA204A data sheet and it seems to me this is not possible. Thanks!

From datasheet,

 

Random numbers are generated through a combination of the output of a hardware RNG and an internal seed

 

The ATSHA204A includes a high-quality RNG that returns a 32-byte random number to the system.

 

AND

 

Because each 32-byte (256-bit) random number is not dependent on past numbers generated on this or any other device,

 

So, I believe - probability is tends to zero.

Kisu Na!!!
