Many C2000™ devices contain a unique device number which can be used by an application for enhancing a security solution. This unique device number may be used in a variety of ways. The following are some examples in which the unique device number may be used.
The implementation of the unique device number has evolved as the C2000 technology and devices have advanced. There are two classes of devices which are distinguished as Class-A and Class-B for the following discussion.
Class-A devices:
Class-B devices:
F2838x
F28002x
For Class-A devices, the device number is pseudo-unique. The term pseudo is meant to clearly communicate that TI does not guarantee the value will be unique for every device, but rather that it should generally be unique.
The 32-bit value provided can be considered as two, 16-bit words. For optimum uniqueness over time, all 32 bits should be used. If only 16 bits are required, TI recommends that the least significant word (LSW) and most significant word (MSW) be XOR’d together. If this cannot be done, then the LSW should be used because the MSW alone may not contain enough variability across material to meet the desired requirements.
