MCRF202

125 kHz Passive RFID Device with Sensor Input

Features

Package Type

PDIP/SOIC

• External sensor input

• Data polarity changes with sensor input condition

• Read-only data transmission

TEST

VSS

VCC

SENSOR

• 96- or 128-bits of factory programming user

memory (also supports 48- and 64-bit protocols)

• Operates up to 400 kHz carrier frequency

• Low-power operation

Description

The MCRF202 is a passive Radio Frequency Identifi-

cation (RFID) device that provides an RF interface for

reading the contents of a user memory array. This

device is specially designed to detect the logic state of

an external sensor, and alters its data transmissions,

based on the condition of the sensor input. The device

outputs a normal bit data stream if the sensor input has

a logic ‘1’ state, but outputs an inverted data stream for

a logic ‘0’ state. In this way, the reader can monitor the

state (condition) of the external sensor input by

detecting whether the data from the device is a normal

or inverted data stream.

• Modulation options:

- ASK, FSK, PSK

• Data Encoding options:

- NRZ Direct, Differential Biphase Manchester

Biphase

• Die, Wafer, PDIP or SOIC package option

• Factory programming and device serialization

Applications

• Insect control

• Industrial tagging

The device is powered by rectifying the incoming RF

carrier signal that is transmitted from the reader. When

the device develops sufficient DC voltage, it transmits

the contents of its memory array by modulating the

incoming RF carrier signal. The reader is able to detect

the modulation and decodes the data being transmit-

ted. Code length, modulation option, encoding option,

and bit rate are set at the factory to fit the needs of

particular applications.

Data

The MCRF202 is available in die, wafer, PDIP and

SOIC packages. The encoding, modulation, bit rate

options, and data fields are specified by the customer

and programmed by Microchip Technology Inc. prior to

shipment. See Technical Bulletin TB023 for more

information on factory serialization (SQTP™).
