Response parameters:
•
Information flags set to 0Fh. DSFID, AFI, VICC memory size (16 bits), and IC reference fields are present.
•
VICC memory size - possible values are:
–
033Fh for ST25TV02K
–
030Fh for ST25TV512
Note:
The first byte is in both cases 03h. It corresponds to a block size of 4 bytes. The 2nd byte is 3Fh when ST25TV
has 64 blocks and 0Fh when ST25TV has 16 blocks.

Get Multiple Block Security Status
When receiving the Get Multiple Block Security Status command, the ST25TV02K/512 send back its security
status for each address block: 0 when block is writable else 1 when block is locked for writing. The blocks security
status are defined by the area security status (and the lock block status). The blocks are numbered from 00h up
to the maximum memory block number in the request, and the value is minus one (–1) in the field. For example,
a value of “06” in the “Number of blocks” field requests will return the security status of seven blocks. This
command does not respond an error if number of blocks overlap areas.
The number of blocks is coded on 1 Byte and only first 256 blocks of ST25TV02K/512 can be addressed using
this command.
