Difference in design for 25 and 25c

I'm not interested in the user feature "continuous", I know it's the non-volatile memory, but the design difference in HW behind this:
is it achieved through exchange of some parts (different parts) or just through adding of additional components?

thanks for hints/pointers/ideas!



The major step was the technology switch from PMOS to CMOS. The latter allows low power memory save as required by continuous memory.


Hi Marcus

Thanks a lot, this was the information I was looking for!

Best regards
