Songzhen,

Just to clarify, there is no encryption support on this device. It only has a Code Security Module that prevents the viewing of secure flash/RAM contents by way of password protection.

Song,

www.ti.com/lit/SPRACD0B discusses a pseudo unique number that the customer may be able to use to encrypt the flash contents with an algorithm of their choice.
