FAB, CMA, and PER are nonvolatile fuses blown at the end of each card life step. Once blown,
these EEPROM fuses can not be reset.
The device responds to a read fuse command with fuse byte.
Table 5-1.
When the fuses are all “1”s, read and write are allowed in the entire memory. Before blowing the
FAB fuse, Atmel writes the entire memory to “1” and programs the fabrication subzone (except
CMC and AR) and the secure code.
• The FAB fuse is blown by Atmel prior to shipping wafers to the card manufacturer.
• The CMA fuse is blown by the card manufacturer prior to shipping cards to the issuer.
• The PER fuse is blown by the issuer prior to shipping cards to the end user.
