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

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.
