MCRF250  
Contactless Programmable Passive RFID Device With Anti-Collision  
FEATURES  
• Anti-collision feature to resolve multiple tags in  
the same RF field  
APPLICATION  
• Read-only data transmission  
RF  
Signal  
• 96 or 128 bits of One-Time Programmable (OTP)  
user memory (also supports 48 and 64-bit  
protocols)  
Transmitter/  
Receiver  
MCRF250  
• Operates up to 150 kHz  
Data  
• On-chip rectifier and voltage regulator  
• Low power operation  
• Factory programming and device serialization  
available  
The MCRF250 is equipped with an anti-collision  
feature that allows multiple tags in the same field to  
be read simultaneously. This revolutionary feature  
eliminates the issue of data corruption due to  
simultaneous transmissions from multiple tags.  
• Encoding options:  
- NRZ Direct, Differential Biphase, Manchester  
Biphase, Biphase IDI  
• Modulation options:  
- FSK, Direct, PSK (change on data change),  
PSK (change at the beginning of a one)  
The user memory array of this device can be  
programmed contactlessly after encapsulation. This  
allows the user to keep encapsulated blank tags in  
stock for on-demand personalization. The tags can  
then be programmed with data as they are needed.  
• Contactless programmable after encapsulation  
DESCRIPTION  
This device is a Radio Frequency Identification (RFID)  
tag that provides a variety of operating modes. The  
device is powered by an external RF transmitter  
(reader) through inductive coupling. When in the reader  
field, the device will transmit the contents of its memory  
array by damping (modulating) the incoming RF signal.  
A reader is able to detect the damping and decodes the  
data being transmitted. Code length, modulation  
option, encoding option and bit rate are set at the  
factory to fit the needs of particular applications.  
These devices are available in die form or packaged in  
SOIC, PDIP or COB modules. The encoding,  
modulation, frequency, and bit rate options are  
specified by the customer and programmed by  
Microchip Technology Inc. prior to shipment. Array pro-  
gramming and serialization (SQTP) can also be  
arranged upon request. See TB023 (page 23) for more  
information.
