MCRF355/360

13.56 MHz Passive RFID Device with Anticollision

The device needs two external antenna coils (L1 and

FEATURES

L2) to pick up the RF magnetic fields and also to send

back encoded (modulated) data to the reader. The two

antenna coils are connected in series. The first coil (L1)

is connected between Antenna Pad A and Antenna

Pad B. The second coil (L2) is connected between

Antenna Pad B and VSS. The MCRF355 requires an

external capacitor to form a resonant circuit along with

the antenna coils.

• Frequency of operation: 13.56 MHz

• Built-in anticollision algorithm for reading up to 50

tags in the same RF field

• “Cloaking” feature minimizes the detuning effects

of adjacent tags

• Manchester coding protocol

• Data modulation frequency: 70 kHz

• 154 bits of user-programmable memory

• Contact programming or factory-programmed

options

The MCRF360 has 100 pF of internal resonance

capacitor between the Antenna Pad A and VSS (across

the coils). This capacitance can be utilized to form a

tuned LC circuit along with the external antenna coils.

See Section 2.2 for external resonant circuits.

• Very low power CMOS design

• Die, wafer, PDIP or SOIC package options

• On-chip 100 pF resonance capacitor (MCRF360)

• Read-only device after programming

The device includes a modulation transistor that is

located between Antenna Pad B and VSS. This

modulation gate is used to send data to the reader. The

modulation transistor is designed to result in approxi-

mately 2Ω of resistance between Drain, which is con-

nected to Antenna Pad B, and Source, which is

connected to VSS, when it is turned-on.

APPLICATION

Signal

MCRF355

Interrogator

The LC circuit is tuned to the operating frequency

(13.56 MHz) of the reader when the modulation

transistor is in a turned-off condition. This condition is

called uncloaking.

Data

PACKAGE TYPE

PDIP/SOIC

As the modulation transistor turns on, there will be a

shorting effect across L2 due to the 2Ω resistance

across it. This results in a change of the inductance of

the antenna coil, and, therefore, the circuit no longer

resonates at 13.56 MHz. This condition is called cloak-

ing.

VPRG

VDD

CLK

Ant. A

Ant. B

VSS

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 data stream consists of 154 bits of Manchester-

encoded data. The code waveforms are shown in

Figure 2-3. The data is sent to the reader by modulating

(AM) the carrier signal (13.56 MHz). After completion of

the data transmission, the device goes into sleep mode

for 100 ms ± 40%. The device repeats the transmitting

and sleep cycles as long as it is energized.

The MCRF355 and MCRF360 are Microchip’s newest

additions to the microID™ family of RFID tagging

devices. They are uniquely designed read-only passive

Radio Frequency Identification (RFID) devices with an

advanced anticollision feature, operating at 13.56 Mhz.

The device is powered remotely by rectifying RF mag-

netic fields that are transmitted from an interrogator

(reader).

Sleep time is determined by a built-in low-current timer.

The variation of sleep time is approximately ± 20%.

The variation of sleep time between each device results

in a randomness of the time slot. Each device wakes up

and transmits its data in a different time slot with

The device has a total of six pads (see Die Layout).

Three are used to connect the external resonant circuit

elements. The additional three pads are used for

programming and testing of the device.
