8.6.1 Manufacturer block
This is the first data block (block 0) of the first sector (sector 0). It contains the IC
manufacturer data. This block is programmed and write protected in the production test.
The manufacturer block is shown in
manufacturer data. This block is programmed and write protected in the production test.
The manufacturer block is shown in
and
for the 4-byte NUID and 7-byte
UID version respectively.
8.6.2 Data blocks
All sectors contain 3 blocks of 16 bytes for storing data (Sector 0 contains only two data
blocks and the read-only manufacturer block).
blocks and the read-only manufacturer block).
The data blocks can be configured by the access bits as
•
read/write blocks
•
value blocks
Value blocks can be used for e.g. electronic purse applications, where additional
commands like increment and decrement for direct control of the stored value are
provided
commands like increment and decrement for direct control of the stored value are
provided
A successful authentication has to be performed to allow any memory operation.
Remark: The default content of the data blocks at delivery is not defined.
8.6.2.1
Value blocks
Value blocks allow performing electronic purse functions (valid commands are: read,
write, increment, decrement, restore, transfer). Value blocks have a fixed data format
which permits error detection and correction and a backup management.

which permits error detection and correction and a backup management.
A value block can only be generated through a write operation in value block format:
•
Value: Signifies a signed 4-byte value. The lowest significant byte of a value is stored
in the lowest address byte. Negative values are stored in standard 2´s complement
format. For reasons of data integrity and security, a value is stored three times, twice
non-inverted and once inverted.
