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™).
