Atmel AT88SA102S

1.3. Fuse Map

The Atmel^®AT88SA102S 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 manufacturer ID and serial number bits initialized by Atmel

have a value of one when shipped from the Atmel factory and transition to a zero when they are burned. Bits 0-63

can never be read, while bits 64-128 can always be read.

Table 1-1. The 128 fuses in the Atmel AT88SA102S chip are arranged in the following manner

Fuse #

Name

Description

BurnFuse Enable

If this fuse is one, then the BurnFuse command is enabled. If it is burned to zero, then

the BurnFuse command is disabled

0 & 2  63

64  86

Secret Fuses

Status Fuses

Fuse Disable

These fuses can be securely written by the BurnSecure command but can never be

read directly with the Read command

These fuses can be written with the BurnSecure command and can always be read

with the Read command

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 1.4. Set by Atmel; can’t be modified in the field

96  127

BurnFuse Enable This fuse is used to prevent operation of the BurnFuse command in the application. This fuse

may only be burned to 0 using the BurnSecure command.

Secret Fuses

These 63-fuses are used to augment the keys stored elsewhere in the chip. Knowledge of

both the internally stored keys and the values of the Secret Fuses are required to generate

the correct response to the Cryptographic command of the AT88SA102S. An arbitrary

selection of these fuses is burned during personalization via the BurnSecure command.

Within this document, “Secret Fuses” is used to refer to the entire array of 64-bits: Fuse[0-

63], even though the value of Fuse[1] is fixed for most applications and its value can be

derived from the operation of the chip.

Status Fuses

These 23-fuses can be used to store information which is not secret, as their value can

always be determined using the Read command. They can be written at the same time as the

secret fuses using the BurnSecure command, or they can be individually burned at a later

time with the BurnFuse command. Two common usage models for these fuses are:

1. Calibration or model number information. In this situation, the 23-bits are written at the

factory. This method can also be used for feature enabling. In this case, the BurnFuse

command should not be run in the field, and the BurnFuse Enable bit should be zero.

2. 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. In this case, the BurnFuse command is

necessary to individually burn one of these 23-bits, and the BurnFuse Enable bit should

be a one.

Within this document, “Status Fuses” is used to refer to the entire array of 24-bits: Fuse[64-

87], even though the value of Fuse[87] is fixed after personalization and cannot be modified

in the field.
