MCRF355/360
The occurrence of the cloaking and uncloaking of the
device is controlled by the modulation signal that turns
the modulation transistor on and off, resulting in com-
munication from the device to the reader.
Description
The MCRF355 and MCRF360 are Microchip’s
13.56 MHz microID™ family of RFID tagging devices.
They are uniquely designed read-only passive Radio
Frequency Identification (RFID) devices with an
advanced anti-collision feature. They are programma-
ble with a contact programmer. The device is powered
remotely by rectifying RF magnetic fields that are trans-
mitted from the reader.
The data stream consists of 154 bits of Manchester-
encoded data at a 70 kHz rate. The Manchester code
waveform is shown in Figure 2-2. After completion of
the data transmission, the device goes into SLEEP
mode for about 100 ms. The device repeats the trans-
mitting and SLEEP cycles as long as it is energized.
During the SLEEP time the device remains in an
uncloaked state.
The device has a total of six pads (see Figure 1-1).
Three (ant. A, B, VSS) are used to connect the external
resonant circuit elements. The additional three pads
(VPRG, CLK, VDD) are used for programming and test-
ing of the device.
SLEEP time is determined by a built-in low-current
timer. There is a wide variation of the SLEEP time
between each device. This wide variation of SLEEP
time results in a randomness of the time slot. Each
device wakes up and transmits its data in a different
time slot with respect to each other. Based on this sce-
nario, the reader is able to read many tags that are in
the same RF field.
The device needs an external resonant circuit between
antenna A, B, and VSS pads. The resonant frequency
of the circuit is determined by the circuit elements
between the antenna A and VSS pads. The resonant
circuit must be tuned to the carrier frequency of the
reader for maximum performance. The circuit element
between the antenna B and VSS pads is used for data
modulation. See Application Note AN707 for further
operational details.
The device has a total of 154 bits of reprogrammable
memory. All bits are reprogrammable by a contact pro-
grammer.
A
contact programmer (part number
PG103003) is available from Microchip Technology Inc.
Factory programming prior to shipment, known as
Serialized Quick Turn ProgrammingSM (SQTPSM), is
also available. The device is available in die, wafer,
bumped wafer, wafer-on-frame, PDIP, SOIC and COB
modules.
The MCRF360 includes a 100 pF internal resonant
capacitor (100 pF). By utilizing this internal resonant
capacitor, the device needs external coils only for the
resonant circuit. Examples of the resonant circuit con-
figuration for both the MCRF355 and MCRF360 are
shown in Section 3.0.
When a tag (device with the external LC resonant cir-
cuit) is brought to the reader’s RF field, it induces an RF
voltage across the LC resonant circuit. The device rec-
tifies the RF voltage and develops a DC voltage. The
device becomes functional as soon as VDD reaches the
operating voltage level.
Note: Information provided herein is preliminary
and subject to change without notice.
The device includes a modulation transistor that is
located between antenna B and VSS pads. The transis-
tor has high turn-off (a few MΩ) and low turn-on (3 Ω)
resistance. The turn-on resistance is called modulation
resistance (RM). When the transistor turns off, the res-
onant circuit is tuned to the carrier frequency of the
reader. This condition is called uncloaking. When the
modulation transistor turns on, its low turn-on resis-
tance shorts the external circuit element between the
antenna B and VSS. As a result, the resonant circuit no
longer resonates at the carrier frequency. This is called
cloaking.
The induced voltage amplitude (on the resonant circuit)
changes with the modulation data: higher amplitude
during uncloaking (tuned), and lower amplitude during
cloaking (detuned). This is called “amplitude modula-
tion” signal. The receiver channel in the reader detects
this amplitude modulation signal and reconstructs the
modulation data.

DATA MODULATION
2.0
FUNCTIONAL DESCRIPTION
The data modulation circuit consists of a modulation
transistor and an external LC resonant circuit. The
external circuit must be tuned to the carrier frequency
of the reader (i.e., 13.56 MHz) for maximum perfor-
mance.
The device contains three major sections: (1) Analog
Front-End, (2) Controller Logic and (3) Memory.
Figure 2-1 shows the block diagram of the device.
2.1
Analog Front-End Section
The modulation transistor is placed between antenna B
and Vss pads and has small turn-on resistance (RM).
This small turn-on resistance shorts the external circuit
between the antenna B and Vss pads as it turns on.
This section includes power supply, Power-on Reset,
and data modulation circuits.
2.1.1
POWER SUPPLY
The transistor turns on during the “Hi” period of the
modulation data and turns off during the “Lo” period.
The power supply circuit generates DC voltage (VDD)
by rectifying induced RF coil voltage. The power supply
circuit includes high-voltage clamping diodes to pre-
vent excessive voltage development across the
antenna coil.
When the transistor is turned off, the resonant circuit
resonates at the carrier frequency. Therefore, the
external circuit develops maximum voltage across it.
This condition is called uncloaking (tuned). When the
transistor is turned on, its low turn-on resistance shorts
the external circuit, and therefore the circuit no longer
resonates at the carrier frequency. The voltage across
the external circuit is minimized. This condition is called
cloaking (detuned).
2.1.2
POWER-ON-RESET (POR)
This circuit generates a Power-on Reset when the tag
first enters the reader field. The RESET releases when
sufficient power has developed on the VDD regulator to
allow for correct operation.
The device transmits data by cloaking and uncloaking
based on the on/off condition of the modulation transis-
tor. Therefore, with the 70 kHz - Manchester format, the
data bit “0” will be sent by cloaking (detuned) and
uncloaking (tuned) the device for 7 µs each. Similarly,
the data bit “1” will be sent by uncloaking (tuned) and
cloaking (detuned) the device for 7 µs each. See
Figure 2-2 for the Manchester waveform.

2.2
Controller Logic Section
This circuit generates a SLEEP time (100 ms 50ꢀ)
for the anti-collision feature. During this SLEEP time
(TOFF), the modulation transistor remains in a turned-
on condition (cloaked) which detunes the LC resonant
circuit.
2.2.1
CLOCK PULSE GENERATOR
This circuit generates a clock pulse (CLK). The clock
pulse is generated by an on-board time-base oscillator.
The clock pulse is used for baud rate timing, data
modulation rate, etc.
2.2.4
READ/WRITE LOGIC
2.2.2
MODULATION LOGIC
This logic controls the reading and programming of the
memory array.
This logic acts upon the serial data (154 bits) being
read from the memory array. The data is then encoded
into Manchester format. The encoded data is then fed
to the modulation transistor in the Analog Front-End
section. The Manchester code waveform is shown in
Figure 2-2.

capacitor that is connected across the two inductors
form a parallel resonant circuit to pick up incoming RF
signals and also to send modulated signals to the
reader. The first coil (L1) is connected between
antenna A and B pads. The second coil (L2) is con-
nected between antenna B and VSS pads. The capaci-
tor is connected between antenna A and VSS pads.
3.0
RESONANT CIRCUIT
The MCRF355 requires external coils and capacitor in
order to resonate at the carrier frequency of the reader.
About one-fourth of the turns of the coil should be
connected between antenna B and VSS; remaining
turns should be connected between antenna A and B
pads. The MCRF360 includes a 100 pF internal reso-
nant capacitor. Therefore, the device needs only exter-
nal coils for the resonant circuit. For example, the
device needs 1.377 µH of inductance for the carrier fre-
quency = 13.56 MHz.
Figure 3-1(b) shows the resonant circuit formed by two
capacitors (C1 and C2) and one inductor.
Figure 3-1(c) shows a configuration of an external
circuit for the MCRF360. By utilizing the 100 pF internal
resonant capacitor, only L1 and L2 are needed for the
external circuit.
Figures 3-1 (a) and (b) show possible configurations of
the external circuits for the MCRF355. In Figure 3-1 (a),

DEVICE PROGRAMMING
MCRF355/360 is a reprogrammable device in Contact
mode. The device has 154 bits of reprogrammable
memory. It can be programmed in the following proce-
dure. (A programmer, part number PG103003, is also
available from Microchip).
4. Power the device off (VDD = VSS) to exit
Programming mode.
5. An alternative method to exit the Programming
mode is to bring CLK logic “High” before VPRG to
VHH (high voltage).
6. Any Programming mode can be entered after
exiting the current function.
4.1
Programming Logic
Programming logic is enabled by applying power to the
device and clocking the device via the CLK pad while
loading the mode code via the VPRG pad (See
Examples 4-1 through 4-4 for test definitions). Both the
CLK and the VPRG pads have internal pull-down
resistors.

NOTICE ON DIE AND WAFER
HANDLING
Every die on the wafer is electrically tested according
to the data sheet specifications and visually inspected
to detect any mechanical damage, such as mechanical
cracks and scratches.
The device is very susceptible to Electro-Static Dis-
charge (ESD), which can cause a critical damage to the
device. Special attention is needed during the handling
process.
Any failed die in the test or visual inspection is identified
by black colored ink. Therefore, any die covered with
black ink should not be used.
Any ultraviolet (UV) light can erase the memory cell
contents of an unpackaged device. Fluorescent lights
and sunlight can also erase the memory cell, although
it takes more time than UV lamps. Therefore, keep any
unpackaged device out of UV light and also avoid direct
exposure of strong fluorescent lights and shining
sunlight.
The ink dot specification:
• Ink dot size: 254 µm in circular diameter
• Position: central third of die
• Color: black
Certain IC manufacturing, COB and tag assembly
operations may use UV light. Operations such as back-
grind de-tape, certain cleaning procedures, epoxy or
glue cure should be done without exposing the die
surface to UV light.

NOTES:
DS21287F-page 20
2002 Microchip Technology Inc.
Note the following details of the code protection feature on Microchip devices:
•
•
Microchip products meet the specification contained in their particular Microchip Data Sheet.
Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.
•
There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our knowl-
edge, require using the Microchip products in a manner outside the operating specifications contained in Microchip's Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
•
•
Microchip is willing to work with the customer who is concerned about the integrity of their code.
Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.”
Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our
products.
