I would like to know the hardware differences between the CYB0644A and CYS0644A.

Dear all,

I looked up the datasheets of CYB0644ABZI-S2D44 and CYS0644ABZI-S2D44.
However, I couldn't figure out the hardware difference between the two models.
I wonder if there is a separate part only for hardware other than the content that supports standard secure(S0) and secure boot(B0) respectively.
For example, I would like to know the difference between 'CYB0644A has structural differences in hardware that TM-F cannot be applied' or
'Booting sequence B0 and S0 are designed differently'.

best regard,

alex.

Hi @alexpark,

Sorry for the delay.

There are no differences between the B0 and the S0 devices from a hardware perspective. Hence there is no Hardware difference between CYB0644A and CYS0644A.

Warm Regards,
