■ MEMORY MAP
This section describes the FRAM memory, which is the internal memory of the MB89R118.
• FRAM Configuration
The FRAM has 2,000 bytes for use as user area and 48 bytes for use as system area.
The FRAM memory areas consist of a total of 256 blocks (250 blocks of user area and 6 blocks of system area).
Each block can store 64 bits (8 bytes) of data.
The block is the unit used for the writing and reading of FRAM data. The memory map of the FRAM is shown below.

Blocks “00H” to “F9H” are user area. The user area is defined as an area that can be accessed when the
corresponding block address is specified. On the other hands, Blocks “FAH” to “FFH” are system area. The system
area is defined as an area that can be accessed only with a specific command (request).
The system area consists of 6 blocks and contains UID, AFI, DSFID, EAS bit, and security status (can write or
cannot write) data for individual block. UID is fixed and cannot be updated. AFI, DSFID, and EAS bit are written
at the factory, and can be updated and locked (disable to write) with commands. (Only EAS bit cannot be locked.)
As shown in above, “FAH” holds the UID, and “FCH” to “FFH” hold the security status information on individual
user areas.
As shown in “• Structure of FBH”, “FBH” contains AFI, AFI lock status byte, DSFID, DSFID lock status byte, and
EAS bit. As shown in the next following figure system areas, “FCH” to “FFH” contains block security status data.

The security status of the user area for 250 blocks is stored in the block security status bits in 4 system area
blocks of “FCH” to “FFH”. 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”.
It is possible to read/write data of 2 blocks (128 bits) at one time in the user area. (If Read Multiple Blocks
Unlimited command is used, up to 256 blocks can be accessed at one time.)
EAS bit is a single bit, and it is used for setting EAS status.

■ DATA ELEMENT DEFINITION
1. Unique Identifier (UID)
The MB89R118 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 described later.
The UID consists of the 3 items shown in the following.
• An 8-bit data whose value is always “E0H” (bit 57 to bit 64)
• An 8-bit IC manufacturer’s code whose value is always “08H”, and is defined by 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 MB89R118
code whose value is “01H”. And the 5 bytes from bit 1 to bit 40 define Chip Information.

2. Application Family Identifier (AFI)
The application family identifier (AFI) identifies the type of application set by the transponder.
The AFI can be written with a command. The AFI is 8-bit data and is stored in the system area of memory (FRAM).
The factory default setting of the AFI is “00H”.

In the status of the AFI_flag setting;
• If the AFI is not supported by the transponder, no response to all requests is returned.
• If the AFI is supported by the transponder, the response is returned only if the value is in accord with
the AFIsent from a reader/writer.
3. Data Storage Format Identifier (DSFID)
The data storage format identifier (DSFID) indicates how data is structured in the transponder (LSI memory
device). The DSFID can be programmed with a command.
The DSFID is 8-bit data and is stored in the system area of memory (FRAM). The factory default setting of the
DSFID is “01H”.

MB89R118
4. Cyclic Redundancy Check (CRC)
When a frame is received, reception of correct data--that is, the characters making up the frame is assumed
only when the value of the cyclic redundancy check (CRC) code is valid. For error-checking purposes, a 2-byte
CRC code value is inserted between data and the EOF signal.
The value of CRC code is required from all the data contained between the SOF and CRC field in each frame.
Method of calculation is provided in ISO/IEC 13239. The initial value of the CRC code provided in ISO/IEC
15693-3 is “FFFFH”.
The CRC code is transferred, beginning with the lowest-order bit in the lowest-order byte.

5. Electronic Article Surveillance (EAS) status
EAS status is 1 bit data (LSB side) , which is stored in the system area of memory (FRAM) . The initial value is
“1”. EAS bit “1” means goods-monitoring status, and EAS bit “0” means that goods-monitoring status is cleared.
EAS status can be written by Write EAS command and can be checked “FBH” block (refer to “■ MEMORY MAP”)
by Read commands such as Read Signal Block command.
Together with Gate type reader/writer, EAS command can support anti-theft security functions.

■ FUNCTION DESCRIPTION
1. Communication from Reader/Writer to Transponder
• Modulation method : Only 10% ASK modulation is supported (100% ASK modulation is not supported) .
• Modulation rate (m) should be 10% to 20% for communication with transponder.
Modulation rate m is defined as m = (a - b)/(a + b) with reference to the modulated waveform shown below.
The values a and b indicate, respectively, the maximum and minimum amplitude of magnetic field transmitted
from a reader/writer.

• Data rate and bit coding : The MB89R118 supports only 1-out-of-4 mode for bit coding.
(Not supports 1-out-of-256 mode.)
• 1-out-of-4 mode
: In 1-out-of-4 mode, 2-bit signals are coded in a period of 75.52 µs as shown
in the following. When coding takes place, the data rate is 26.48 Kbps (fc/512). Each
signal is transmitted beginning with the lowest bit.

2. Communication from Transponder to Reader/Writer
• Minimum load modulation amplitude (Vlm) : 10 mV (based on ISO/IEC 10373-7)
• Load modulation subcarrier frequency (fs) : 423.75 kHz(fc/32)
The MB89R118 supports only a 1-subcarrier system.
(Not supports 2-subcarrier system.)
• Data rate : The MB89R118 supports the following 2 data rate modes :
• Low data rate
• High data rate
One of the 2 data rate modes is specified by the Data_rate_flag (described later) sent from
the reader/writer. In low data rate mode, the data rate is 6.62 Kbps (fc/2048); in high data rate
mode, it is 26.48 Kbps (fc/512).
Also the Fast commands (Custom commands) supports the 2 data rate modes specified by
the Data_rate_flag. In Low data rate mode, the data rate is 13.24 Kbps (fc/1024) ; in high data rate
mode, it is 52.97 Kbps (fc/256)
• Bit coding : The Manchester coding is used for the bit coding. The following figure shows the signals
modulated in high data rate mode when standard command is used, and the next following
figure shows the same signals when fast command is used. In low data rate mode of both
standard commands and fast commands, the number of pulses for subcarrier and data transfer
time is 4 times as large as the number in high data rate mode.

• Data frame : A data frame sent from a transponder starts with a start-of -frame (SOF) signal and ends with an
end-of-frame (EOF) signal. The following figure shows the SOF and EOF signals sent in high
data rate mode when standard command is used, and the next following figure shows the same
signals when fast command is used.
In low data rate mode of both standard commands and fast commands, the number of pulses
and data transfer time is 4 times as large as the number in high data rate mode, which is the
same as explained in the figure below. A reader/writer that has sent a frame to a transponder
must be enabled to receive a frame from the transponder within 300 µs after the reader/writer
has completed sending of the frame.

3. FRAM Data Protection if Power Lost During Data Writing
If the power to FRAM is lost while data is being written to it, data may take on unexpected values, possibly
adversely affecting system operation.
The MB89R118’s FRAM is accessed (updated) in byte units.
The MB89R118 circle confirms that the level of power supply voltage is sufficient before data is written to each
byte.
However, since write commands access more than one byte at once a power loss in the middle of write commands
may result in a mixture of new written data and still remaining old data. As a result, confirm success of a write
command with read command after each write command.
4. Requests/Responses
A request is sent from the reader/writer to the transponder. In reply to the request, the transponder sends a
response to the reader/writer.
Each request, and each response, is transmitted in a single frame.
• Structure of requests and responses
A request consists of the following 5 fields :
• Flag
• Command code
• Parameter (required or optional depending on the command)
• Application data
• CRC
A response consists of the following 4 fields :
• Flag
• Parameter (required or option depending on the command)
• Application data
• CRC
Each byte is transferred, beginning with the lowest bit. When two or more bytes are transferred, transfer begins
with the lowest one.
Set the RFU_flag always to “0”.
5. Operating Modes
The MB89R118 has the following 3 operating modes :
Each mode specifies a different mechanism for how the transponder returns a response in reply to a request
from the reader/writer :
• Addressed mode
The MB89R118 enters addressed mode when the Address_flag is set to “1”.
In addressed mode, a request includes a UID (the Address_flag is set to “1” simultaneously), and only the
transponder that matches the UID in the request returns a response. If no transponder that matches the UID
exists, a response is not returned.
13
MB89R118
• Non-Addressed mode
The MB89R118 enters non-addressed mode when the Address_flag is set to “0”.
In non-addressed mode, a request does not include a UID. The transponders that receive the request execute
processing and return response in accordance with the command in the request.
• Select mode
The MB89R118 enters select mode when the Select_flag is set to “1”, and the address_flag is set to “0”.
In select mode, do not include a UID as a request. Of the transponders that receive the command, only the
transponder in the selected state executes processing and returns a response in accordance with the command
in the request.

8. Anti-Collision Algorithm
The MB89R118 executes an anti-collision sequence loop based on an algorithm that complies with ISO/IEC
15693-3.
The anti-collision algorithm is designed to examine the transponders located within reader/writer communication
areas on the basis of UID.
A transponder itself can recognize the existence of other transponders only by information supplied from the
reader/writer. Only the reader/writer can recognize the existence of multiple transponders by itself. It is therefore
the reader/writer that plays the primary role of algorithm executor.
The reader/writer issues an Inventory request (command) to transponders, and some transponders return
responses while other transponders do not according to the algorithm explained in “10. Execution of Inventory
Command by a Transponder”.

MB89R118
9. REQUEST PARAMETER
• Request Parameter Settings
Set the reader/writer as follows before issuing the Inventory command.
• The Nb_slots_flag (bit6), which is a request flag, is set to the desired value :
“0” : 16 slots (for plural transponders)
“1” : 1 slot (for single transponder)
• A mask length and a mask value are added after the command code.
• The mask length is the number of bits in the mask value.
• The mask value is integer bytes of data, transmitted beginning with the lowest bit. If the mask data is not
a multiple of 8 (bits) in length, 0 is padded on the MSB side of the mask value so that the data is in units of bytes.
The following figure shows an example of the mask value with padding. Since the mask length is 12 bits, the
mask value is padded with 4 bits on the MSB side so that the mask data is in units of bytes (2 bytes = 16 bits in
this case).
If the AFI flag in the request flags is set in the format explained in “• Structure of the request frame of 6 Request
Format”, an AFI field is added to the format. The command ends with transmission of an EOF signal as described
in “1. Communication from Reader/Writer to Transponder”. Thereafter, processing in the first slot starts immediately. To proceed to the next slot, the reader/writer sends an EOF signal.

10. Execution of Inventory Command by a Transponder
A transponder returns a response to the reader/writer when its UID is equal to the value that consists of the
mask value and the number of slots. The mask value is sent in the Inventory command, and the number of slots
is determined by the number of times the EOF signal is transmitted.

11. Anti-Collision Sequence
• Execution of anti-collision sequence
A typical anti-collision sequence that is applied when the number of slots is 16 is executed as follows :
1) The reader/writer sends an Inventory command.
The Nb_slots_flag of the request flags is set to “0” to specify the number of slots.
2) In slot 0, transponder 1 returns a response. Other transponders do not respond. The reader/writer recognizes
the UID of transponder 1.
3) The reader/writer sends an EOF signal to proceed to the next slot.
4) In slot 1, transponders 2 and 3 respond. Because the reader/writer cannot recognize the UIDs of the
2 transponders, it remembers that a collision has occurred in slot 1.
5) The reader/writer sends an EOF signal to proceed to the next slot.
6) In slot 2, the reader/writer does not detect any response from transponders and sends an EOF signal to
proceed to the next slot.
7) In slot 3, transponders 4 and 5 respond causing another collision.
8) The reader/writer sends a request (for example, a Read Block command, described later) to transponder 1
whose UID that it has already recognized.
9) When an SOF signal is received, all transponders exit the anti-collision sequence. If transponder 1 is specified
using addressed mode, only transponder 1 can return a response to the reader/writer.
10) Every transponder is enabled to receive another request from the reader/writer. If the Inventory command
is executed again, the sequence starts at slot 0.
11) The mask value is the data whose size is a number of bytes integer and which is sent in LSB-first mode. If
the size of the data to be masked is not a multiple of 8 (bits), the unnecessary bits on the MSB side of the
mask value are padded with “0” to make the mask value byte data.

• Timing definitions
• Period during which the transponder waits for the start of response transmission after an EOF signal transmitted
from the reader/writer : t1_a
After detection of an EOF signal sent from the reader/writer, each transponder must wait for a certain time (t1_a)
before sending a response to the reader/writer. t1_a begins at the rising edge of the EOF pulse. The following
table lists the defined minimum, nominal, and maximum values of t1_a.
Also, ISO/IEC 15693-3 specifies that if the transponder detects a modulated signal from the reader/writer within
t1_a, the transponder must reset the t1_a timer and wait for another t1_a period before sending a response to
the reader/writer; otherwise, the slot counter must be incremented. On the MB89R118, however, the transponder
ignores all modulated signals sent from the reader/writer during the following tmit.
21
MB89R118
• Period during which the transponder ignores modulated signals after an EOF signal transmitted from the
reader/writer : tmit
After detection of an EOF signal sent from the reader/writer, each transponder must ignore the 10% modulated
signals from the reader/writer for a time (tmit).
tmit begins at the rising edge of the EOF pulse. The minimum value of tmit is defined as 4384/fc (323.3 µs) +
tnrt, as shown in the following table.
In the above expression, tnrt stands for the response time of the transponder.
• Period during which the reader/writer waits before sending a request : t2_a
After a response to a request (except a Inventory command or a Stay Quiet command) from a transponder has
been received, the reader/writer must wait for a certain period (t2_a) before sending the next request. The
minimum value of t2_a is shown in the following table.
If the reader/writer sends a Stay Quiet command to a transponder, the transponder does not return any response.
In this case, t2_a begins at the point at which 9.44 µs has passed since the rising edge of the EOF pulse for the
Stay Quiet command.
If the reader/writer sends an Inventory command to a transponder, the wait time t2_a follows the specifications
of t2inv (period during which the reader/writer waits before sending a request during execution of the Inventory
command) described below.
• Period during which the reader/writer waits before sending a request during execution of the Inventory command : t2inv
While an Inventory command is being executed, the reader/writer sends an EOF signal when it shifts to the next
slot. In this case, the wait time is defined as follows depending on whether transponders return responses :
-
Wait time applied when the reader/writer has received one or more responses : t2invwr
When the reader/writer has received one or more responses, the reader/writer must wait until responses
from the transponders have been completed (that is, the reader/writer receives an EOF signal or tnrt passes).
After that, the reader/writer must wait until t2_a passes before sending an EOF signal to switch to the next slot.
-
Wait time applied when the reader/writer has not received any responses : t3_a
When the reader/writer has not received any responses from the transponders, the reader/writer must wait
until t3_a passes before sending an EOF signal. In this case, t3_a begins at the rising edge of the EOF pulse
that was sent previously. The minimum value of t3_a is defined as 4384/fc (323.3 µs) + tnrt, as shown in the
following table.

On receiving the Write Single Block command, the transponder writes the single-block data included in the
request to the specified block.
The transponder performs verification after writing and returns an error code if the writing has failed.
If the Option_flag (bit 7) is “0”, the transponder shall return its response when it has completed the write operation
starting after <t1nom + a multiple of 4096/fc (302.1 µs)> with total tolerance of ± 32/fc (2.4 µs) and latest within
20 ms. If it is “1”, transponder shall wait for the reception of an EOF from the reader/writer and upon such
reception still return its response. (However, if an EOF is not sent within 38 ms, the time-out occurs and the
transponder can receive another command.)

• Description of command
On receiving the Lock Block command, the transponder locks the data stored in one specified single-block.
The transponder performs verification after writing and returns an error code if the writing has failed.
If the Option_flag (bit 7) is “0”, the transponder shall return its response when it has completed the lock operation
starting after <t1nom + a multiple of 4096/fc (302.1 µs)> with total tolerance of ± 32/fc (2.4 µs) and latest within
20 ms. If it is “1”, transponder shall wait for the reception of an EOF from the reader/writer and upon such
reception still return its response. (However, if an EOF is not sent within 38 ms, the time-out occurs and the
transponder can receive another command.)

2-4. Read Multiple Blocks Command
• Description of command
On receiving the Read Multiple Blocks command, the transponder returns the data stored in the specified
successive blocks to the reader/writer as a response.
Up to 2 blocks of data can be read for one request.
If the Option_flag (bit 7) is “1”, the transponder adds block security status information in the response. If the
Option_flag (bit 7) is “0”, the transponder returns only the data in the specified blocks to the reader/writer.
The value of the “number of blocks” field specified in the request is the expected number of blocks minus 1.
Setting the number of blocks to “01H” makes a request to read 2 blocks. Setting the number of blocks to “00H”
makes a request to read 1 block (the request having the same effect as the Read Single Block command).
Note : For execution in the addressed mode, the Read Multiple Blocks command must be run without shutting off
the RF power supply after obtaining the UID, for example, using the Inventory command. No response may
be expected when RF power supply is not stable.

2-5. Write Multiple Blocks Command
• Description of command
On receiving the Write Multiple Blocks command, the transponder writes the successive multiple-block data
included in the request to the specified blocks.
Up to 2 blocks of data can be written for one request.
The transponder performs verification after writing and returns an error code if the writing has failed. Up to 2
blocks of data can be written for one request. The number of blocks specified in the Write Multiple Blocks
command is similar to the number of blocks specified in the Read Multiple Blocks command. The value of the
number of blocks field specified in the Write Multiple Blocks command is obtained by subtracting 1 from the
number of the expected blocks to be written.
Setting the number of blocks to “01H” makes a request to write 2 blocks. Setting the number of blocks to “00H”
makes a request to write 1 block (the request having the same effect as the Write Single Block command).
If at least one of the blocks specified for data writing is locked, the transponder does not write any data and,
instead, returns an error code.
27
MB89R118
If the Option_flag (bit 7) is “0”, the transponder shall return its response when it has completed the write operation
starting after <t1nom + a multiple of 4096/fc (302.1 µs)> with total tolerance of ± 32/fc (2.4 µs) and latest within
20 ms. If it is “1”, transponder shall wait for the reception of an EOF from the reader/writer and upon such
reception still return its response. (However, if an EOF is not sent within 38 ms, the time-out occurs and the

2-11. Lock DSFID command
• Description of command
On receiving the Lock DSFID command, the transponder locks (write disable) the stored DSFID.
The transponder performs verification after writing and returns an error code if the writing has failed.
If the Option_flag (bit 7) is “0”, the transponder shall return its response when it has completed the lock operation
starting after <t1nom + a multiple of 4096/fc (302.1 µs)> with total tolerance of ± 32/fc (2.4 µs) and latest within
20 ms. If it is “1”, transponder shall wait for the reception of an EOF from the reader/writer and upon such
reception still return its response. (However, if an EOF is not sent within 38 ms, the time-out occurs and the
transponder can receive another command.)
Once the Lock DSFID command has been received, the DSFID cannot be changed by the Write DSFID command.

Up to 2 blocks of data can be read for one request.
If the Option_flag (bit 7) is “1”, the transponder adds block security status information in the response. If the
Option_flag (bit 7) is “0”, the transponder returns only the data in the specified blocks to the reader/writer.
The value of the “number of blocks” field specified in the request is the expected number of blocks minus 1.
Setting the number of blocks to “01H” makes a request to read 2 blocks. Setting the number of blocks to “00H”
makes a request to read 1 block (the request having the same effect as the Fast Read Single Block command).
Note : For execution in the addressed mode, the Fast Read Multiple Blocks command must be run without shutting
off the RF power supply after obtaining the UID, for example, using the Inventory command. No response
may be expected when RF power supply is not stable.

3-8. Fast Write Multiple Blocks Command
• Description of command
The Fast Write Multiple Blocks command is the same as the Write Multiple Blocks command that writes the
successive multiple-block data included in the request. The datarate in the response is twice as defined in ISO/
IEC 15693.
Up to 2 blocks of data can be written for one request.
The transponder performs verification after writing and returns an error code if the writing has failed. Up to 2
blocks of data can be written for one request. The number of blocks specified in the Fast Write Multiple Blocks
command is similar to the number of blocks specified in the Read Multiple Blocks command. The value of the
number of blocks field specified in the Fast Write Multiple Blocks command is obtained by subtracting 1 from
the number of the expected blocks to be written.
Setting the number of blocks to “01H” makes a request to write 2 blocks. Setting the number of blocks to “00H”
makes a request to write 1 block (the request having the same effect as the Fast Write Single Block command).
If at least one of the blocks specified for data writing is locked, the transponder does not write any data and,
instead, returns an error code.
If the Option_flag (bit 7) is “0”, the transponder shall return its response when it has completed the write operation
starting after <t1nom + a multiple of 4096/fc (302.1 µs)> with total tolerance of − 32/fc to + 32/fc (2.4 µs) and
latest within 20 ms. If it is “1”, transponder shall wait for the reception of an EOF from the reader/writer and upon
such reception still returns its response. (However, if an EOF is not sent within 38 ms, the time-out occurs and

■ STATE TRANSITION DIAGRAM
• Definition of states
Each state of MB89R118 is defined as follows.
• Power-Off the state : IF the power-off state, a transponder can not fulfill the function so that the voltage from
a reader/writer is underpowered.
• Ready state
: In the ready state, the MB89R118 can execute all commands from a reader/writer if
the Select_flag is not set.
• Quiet state
: In the quiet state, the MB89R118 can execute the command from a reader/writer
for which the Inventory_flag is not set and the Address_flag is set.
• Selected state
: In the selected state, the MB89R118 can execute the command from a reader/writer
for which the Select_flag is set.
As shown in figure below, the MB89R118 moves from one state to another according
to the status of power and by a command.

■ NOTES ON USING
• Notes on the radio interface
- It is the user’s responsibility to reduce the effects of the electromagnetic waves produced by the reader/writer.
- The user must optimize the shapes of the antenna coils for transponder and reader/writer so that they match
the transmission distance and installation space required for the user’s application.
- If the user intends to access multiple transponders from a reader/writer, the interference between
transponders or between the reader/writer and a transponder may degrade communication performance
(transmission distance and communication time) . Therefore, a user who intends to design a system using
multiple transponders should consider this point.
• FRAM reliability
Up to 1010 writes to the FRAM memory and 10 years of data retention at + 55 °C are guaranteed. For the data
retention characteristics at + 150 °C or higher, see “■ SHIPPING METHOD AND RECOMMENDED ASSEMBLY
CONDITIONS”.
• Difference between rating of ISO/IEC 15693 and MB89R118 implementation.
The table comparing rating of ISO/IEC 15693 to method of MB89R118 is shown in following.
Note that the MB89R118 implementation does not support following ratings.
• 100% amplitude shift keying (ASK) modulation method
• 1-out-of-256 mode data coding
• 2-subcarrier
• Supports more than 3 blocks for Read/Write Multiple Blocks command
(If “Read/Write Multiple Blocks Unlimited command” of Custom commands is used, enables to support more
than 3 blocks.)
