Secure Boot Supported ARM MCU

akaradag — Wed, 05 Jul 2023 08:07:13 GMT

Hi NXP technical support team,

I am looking for secure boot supported ARM MCU with features in below,

- RSA-4096 bit public keys

- x509 cert format support

- sha256 hash function

- OTP or PFR storage support

I see a few products (i.e. LPC5500), but cannot compare them. Could you please assist me to see all options with comparing of secure boot features... like a table

#mcu #secureboot #32-bit-arm #RSA-4096-#sha256

best regards, Anil

Hello @akaradag

What do you want to compare, the four parts you list? We can not compare them, because they are not the same class, responsible for different functions, you can google them to know detail.

Secure boot of lpc55sxx use all the functions you mentioned. about secure boot, you can have a look at chapter 7 of UM11126.

Hi @Alice_Yang ,

Thanks for your quick answer. There is a capability on NXP website to compare products. But, secure boot features are not in the property list NXP gives.

I can see details via checking data-sheet of the each family one by one. There might be ann internal method that creates a comparison table with all possible options. Can you do?

Hello @akaradag

LPC55S6x/2x/1x/0x and LPC55s3x all support secure boot, and part number without "S" doesn't suport it. About Secure boot, LPC55S6x/2x/1x/0x is same, there is some difference for lpc55s3x.

There is a security feature comparison table:
