MEMORY CONFIGURATION
This section describes the FRAM memory, which is the internal memory of the MB89R119.
•
FRAM Configuration
The FRAM has 232 bytes for use as user area and 24 bytes for use as system area.
The FRAM memory areas consist of a total of 64 blocks (58 blocks of user area and 6 blocks of system area).
Each block can store 32 bits (4 bytes) of data.
The block is the unit used for the writing and reading of FRAM data. The memory configuration of the FRAM is
shown below.

Blocks “00
H
” to “39

” are user area. The user area is defined as an accessible area when the corresponding
block address is specified. On the other hands, Blocks “3A
H
” to “3F
H
” are system area. The system area is defined
as an accessible area only with a specific command.
The system area consists of 6 blocks and contains RFU, UID, AFI, DSFID, EAS, IC reference and security status
(can write or cannot write data). UID, IC reference and RFU is fixed and cannot be updated. The initial data of
AFI, DSFID, and EAS are written at the factory, and they can be updated and locked (disable to write) with
commands. (EAS bit cannot be locked.)
As shown in above, “3B
H
” and “3C

” and “3F

” are used to store the
security status information such as user areas, AFI, and DSFID.
“3D

The security status of the user area is stored in the block security status bit in system area blocks of “3E
H
” and
“3F
H
” per bit in each block. A user area is unlocked when the corresponding block security status bit is “0”; it is
locked (disable to write state) when the corresponding block security status bit is “1”. In the same way, the security
status of AFI and DSFID are stored in “AFI Lock Status” and “DSFID Lock Status” respectively.
It is possible to read up to 64 blocks data by one command and to write up to 2 blocks data by one command.
EAS bit is 1 bit, and it is used for setting EAS status.

DATA ELEMENT DEFINITION
1. Unique Identifier (UID)
The MB89R119 has a 64-bit unique identifier (UID) that complies with ISO/IEC 15693-3. The UID is used to
distinguish a transponder from another transponder in the anti-collision algorithm.
The UID consists of the 3 items shown in the following.
•
The MSB 8-bit data whose value is always “E0
H
” (bit 57 to bit 64)
•
An 8-bit IC manufacturer code whose value is always “08
H
” according to ISO/IEC 7816-6/AMI (bit 49 to bit 56)
•
Unique 48-bit serial number assigned by Fujitsu (bit 1 to bit 48)
Among the unique 48-bit serial number assigned by Fujitsu, the 1 byte from bit 41 to bit 48 defines MB89R119
code whose value is “02
H
”. And the 5 bytes from bit 1 to bit 40 define Chip Information.
