Chapter 17
IIM/Fusebox
17.1
The IC Identification Module (IIM) provides an interface for reading and programming information stored
in on-chip fuse elements.
17.2
The IIM provides the primary user-visible mechanism for interfacing with on-chip fuse elements. Among
other uses, e-fuses can be used for unique chip identifiers, cryptographic keys, and various control signals
requiring permanent non-volatility.
The IIM consists of a master controller, a fuse value shadow cache, and a set of registers to hold the values
of signals visible outside the module. Two 256-bit fuse banks are implemented on the MPC5125.
The e-Fuses may be blown under software control at the customer factory or in the field. They include a
mechanism to inhibit further blowing of fuses (write-protect) to support secure computing environments.
The fuse values may also be overridden by software without modifying the fuse element. Similar to the
write-protect functionality, the override functionality can also be permanently disabled.
17.2.1
17.2.2
The IIM is in its functional mode (all specified functionality available) any time it is out of reset and
supplied with the proper clocks.
For programming the external FUSE programming supply, AVDD_FUSEWR must be applied.
