OMAP5910 Die ID
An electrically readable die ID permits tracing of individual dies back to
manufacturing data and aids in rapid ramp. Access to the die ID by both the
tester and the application is necessary.
The die ID is a 64-bit code. Of these, 56 bits (bits 0 – 55) are data bits that con-
tain x and y coordinates of the die, wafer number, lot number, and manufactur-
ing number. Eight bits (bits 56 – 63) are check bits computed using a Hamming
code.
The die ID can be read by software via the private TIPB (see Table 6–52).
