1.2  
Fuse Map  
The AT88SA100S chip incorporates 128 one-time fuses within the chip. Once burned, there is no way to reset the value of a  
fuse. Fuses, with the exception of the manufacturing ID and serial number bits, which are initialized by Atmel, have a value of  
one when shipped from the Atmel factory and transition to a zero when they are burned.  
Table 1-1. The 128 Fuses in the Atmel AT88SA100S Chip are Arranged in the Following Manner:  
Fuse #  
Name  
Description  
0 – 7  
Fuse Lock Bits  
Each bit, when zero, locks the current value of the corresponding 16-bit block of the  
fuse array, see below for more details  
8 83  
Status Fuses  
Status Fuses  
These fuses can be written with the BurnFuse command and can always be read with  
the Read command. They are totally user-defined  
84 87  
These fuses can be written with the BurnFuse command and can always be read with  
the Read command. They are user-defined, but have special significance for the Pause  
Long command. See Section 6.3  
87  
Fuse Disable  
The MAC command ignores the values of Fuse[0-86] while this fuse is an one  
Once it is burned to zero, the BurnSecure command is disabled  
88 95  
Fuse MfrID  
Fuse SN  
See Section 1.3. Set by Atmel, cannot be modified in the field  
See Section 1.3. Set by Atmel, cannot be modified in the field  
96 127  
Fuse Lock Bits  
Status Fuses  
These eight fuses can be used to prevent further writing of the status fuses. Bit 0, when burned, locks  
Fuse[0-15] from being modified, Bit[1] locks Fuse[16-31] and so on up through bit five, which locks  
Fuse[80-87]. Fuse[88-127] can never be modified with the BurnFuse command.  
Note:  
Burning bit zero has the effect of preventing any changes to the current value of the lock bits  
These fuses can be used to store various information which are not secret. Their value can always be  
determined using the Read command. They can be individually burned using the BurnFuse command.  
Two common usage models for these fuses are:  
1. Consumption logging, i.e. burn one bit after every n uses, the host system keeps track of the  
number of uses so far for this serial number since the last fuse burn.  
2. Model number information. In this situation, the bits are written at the factory and their value is  
locked to prevent modifications in the field. This method can also be used for feature enabling.  
1.3  
Chip Identification  
The chip includes a total of 72-bits of information that can be used to distinguish between individual chips in a reliable manner.  
The information is distributed between the ROM and fuse blocks in the following manner.  
Serial Number  
This 48-bit value is composed of ROM SN (16-bits) and Fuse SN (32-bits). Together they form a serial  
number that is guaranteed to be unique for all devices ever manufactured within the Atmel  
CryptoAuthenticationfamily. This value is optionally included in the MAC calculation.  
Manufacturing ID  
This 24-bit value is composed of ROM MfrID (16-bits) and Fuse MfrID (8-bits). Typically this value is  
the same for all chips of a given type. It is always included in the cryptographic computations.
