Applications
Item Level Tagging: To read and write multiple
items in long read range environment.
Anti-Counterfeit: The device has a unique
feature to distinguish between paid, unpaid or
returned merchandise.
Inventory Management: Tag’s data can be read
or updated (written) in multiple tags and long
range environment. Its memory (32 blocks, 1 Kbit,
each block = 32 bits) is well organized for the
inventory management applications.
Product Identifications
• Airline Baggage Tracking
• Book Store and Library Book ID
Low Cost Animal Ear Tags: The device’s long
range reading performance combined with 1 Kbit
of memory is suitable for animal tagging applica-
tions. Tag cost can be cheaper and read range is
much longer than existing 125 kHz conventional
animal ear tags.
Toys and Gaming Tools: Device’s anti-collision
feature for reading and writing allows to make
intelligent interactive toys and gaming tools.
Access Control and Time Attendance Cards:
Device’s long range performance allows to make
long range access control, parking lot entry, and
time attendance cards.
Inexpensive finished tags and readers are available
from Microchip’s worldwide OEM partners. Please

To enhance data integrity for writing, the device
includes an anti-tearing feature. This anti-tearing
feature provides verification of data integrity for
incomplete write cycles due to failed communication
between the Interrogator and the device during the
write sequences.
1.1 Device’s Communication with
Interrogator
The device can be operated in either Fast Read
Request (FRR) or Fast Read Bypass (FRB) mode,
depending on the status of bit 31 (FR: bit) of Block 0. If
the FR bit is set, the device is operated in FRR mode,
and FRB mode, if the FR bit is cleared. The FR bit is
always reprogrammable and not write-protectable. The
FRR mode is a default setting. The communication
between the Interrogator and tag starts with a FRR or
FRB command.
In FRR mode, the device sends a response only when
it receives the FRR command, not the FRB command.
Conversely, the device in FRB mode sends a response
when it receives the FRB command only, not the FRR
command.
If the device is set to FRR mode and also set to TTF
mode (TF bit = set), the device can send the FRR
response as soon as it is energized.
One of the main purposes of using the two different
modes (FRR and FRB) is to use the device effectively
in the item level supply-chain application, where a rapid
identification and an effective anti-collision read/write
process is needed (i.e., to identify whether it is a paid
or unpaid item, or whether it passed one particular point
of interest or not). This can be done by either checking
the status of the FR bit or by checking the response of
the tag to the command. For this reason, the FR bit is
also called an Electronic Article Surveillance (EAS) bit.
1.1.1 OPERATION OF TAG IN FRR MODE
If the device is in the FRR mode (FR bit = set), the
communication between the Interrogator and the
device can start in two ways, depending on the status
of TF (Bit 30 of Block 0). If the TF bit is cleared, it is
called ITF mode. In this case, the tag waits for the
Interrogator’s FRR command and sends the FRR
response data when it sees the FRR command. If the
TF bit is set, the device is in a TTF mode. In this case,
the tag sends the FRR response as soon as it is
energized, even without the FRR command. The tag
has a short listening window (1 ms) immediately after
the FRR response. The Interrogator sends its next
command during this listening window.
The FRR response includes the 32 bits of tag ID and
FRF (Blocks 3 -5). See Tables 7-3, 7-4 and 7-6 for
data. The Interrogator identifies which tags are in the
field by receiving their FRR responses.
Based upon the FRR response, the Interrogator will
send Matching Code 1 (MC1) or Matching Code 2
(MC2) during the tag’s listening window. The Interroga-
tor sends the MC1 to put the tag into Sleep mode. Tags
in Sleep mode never respond to any command.
Removal of the Interrogator’s RF energy from the
device is the only way to wake-up the device.
If the tag needs further read/write processing, the
Interrogator sends the MC2, followed by a Read or
Write command. After the completion of reading or
writing of block data, the Interrogator sends an End
command to put the tag into Sleep mode.
The reading and writing of the FRR devices takes place
in the Anti-collision mode. For instance, if there are
multiple tags in the field, the Interrogator selects one
tag at a time by controlling the tag’s time slot for the
FRR response. The Interrogator repeats this sequence
until all tags in its field are processed:
- send FRR command
- receive FRR response
- send Matching Code 1 or 2 at tag’s listing
window
- send Read Block command/or send Write
Block command and data
- verify read/write response
- send End command
- verify the End command response
- look for other tag’s FRR responses
1.1.2 OPERATION OF TAG IN FRB MODE
The communication with the device in the FRB mode is
initiated by the FRB command only. If the device sees
the Interrogator’s FRB command, it sends its 32-bit tag
ID and waits for the MC2. This is followed by a Read or
Write command. Once the device is read or written, the
Interrogator sends an End command. Unlike the FRR
mode, the reading and writing of the tag are processed
in a non Anti-collision mode.
See Section 6.0 “Read/Write Anti-Collision Logic”,
for the read and write anti-collision algorithm. See
Example 9-1 for command sequences and device
responses.

Note 1: The bond pad size is that of the passivation opening. The metal overlaps the bond pad passivation by at
least 0.1 mil.
2: Metal Pad Composition is 98.5% Aluminum with 1% Si and 0.5% Cu.
3: As the die thickness decreases, susceptibility to cracking increases. It is recommended that the die be as
thick as the application will allow.
4: The Die Passivation Thickness (1.3 µm) can vary by device depending on the mask set used. The
passivation is formed by:
- Layer 1: Oxide (undoped oxide)
- Layer 2: PSG (doped oxide)
- Layer 3: Oxynitride (top layer)
5: The conversion rate is 25.4 µm/mil.
Notice: Extreme care is urged in the handling and assembly of die products since they are susceptible to
mechanical and electrostatic damage.
