lpc4337 vs lpc43s37 aes encryption

Hello

I need help : i have questions about lpc4337 vs lpc43s37

it seems the only difference betwin both is the aes encrytion.

i need to encrypt with basic aes encryption....and i found an Application Note from NXP (AN11241) and the software library for use it.

it seems i don't need to have lpc43s37 to do that : the lpc4337 can use this library without aes peripheral i'm right?.

thanks

yes, AN11241 is SW lib, you can port it to LPC4337 to implement AES encryption.

But please note:

The library has been tested on the following targets: LPC11Axx (Cortex-M0 based), LPC1769 (Cortex-M3 based). For porting the library to other targets, the user may extend or modify the target definition in the cipher.h file.

For more, see AN11241.

Have a nice day,

Jun Zhang
