CHANDLER, Ariz., SCAN-TECH '99 Booth #1948, Oct. 5 /PRNewswire/ --
Microchip Technology Inc. (Nasdaq: MCHP) today introduced the world's first
RFID tagging IC with a sensor input that contactlessly provides a serial
number or other fixed data and determines the logic state of an external
sensor output or switch position. The MCRF202 RFID 125 KHz microID(TM)
tagging IC is ideally suited for industrial RFID applications using sensors or
switches.
The MCRF202 features a sensor input to sense the state of an external
switch or logic level. The entire data stream is inverted when logic 0 is
applied and normal data stream when logic 1 is applied. With this unique
feature, design engineers can now power and determine the state of a passive,
batteryless switch or sensor without eye contact and without electrical
contact while simultaneously reading its serial number or other data stored in
the on-chip memory. Any sensor that can be adapted to provide a single binary
output can be powered and read contactlessly, including leak sensors, strain
gauges, temperature sensors with thermal limits, and make/break contacts.
The MCRF202 allows users to read the location, serial number and sensor
state in buried pipes, building components buried in concrete or walls, even
biological sensors inside living animals, in a non-intrusive manner. This
eliminates the digging, cutting or destruction of property, dramatically
reducing costs and improving time to data access.
The MCRF202 features 96 or 128 bits of read-only memory; encoding options
of NRZ Direct, Differential Biphase, and Manchester Biphase; and modulation
options of Direct, FSK, and PSK. A DC output for powering external switching
circuits or other low-current devices allows the MCRF202 to be used as an
AC->DC RF power rectifier or voltage regulator. Current consumption is
inversely proportional to read range.
The device is powered by an external RF transmitter through inductive
coupling and supplies a DC source to the external switch. When exposed to a
reader field, the device transmits the contents of its memory array by damping
(modulating) the incoming RF signal. The reader is able to detect the
modulation 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. Data fields are also factory-serialized in the
customer's format.
To support development of systems utilizing its MCRF202, Microchip offers
the DV103001 microID Developer's Kit, which allows designers to contactlessly
program and read an assortment of tags. This is a complete tool for education
and development of RFID systems based on Microchip's microID family of tags,
including a contactless programmer, reference readers, schematics, software
and product samples. A design reference guide complete with PICmicro(R) 8-bit
microcontroller code files is included.
Pricing for the MCRF202 in 10,000-unit quantities is $0.70 each for die in
wafer and wafer on frame; $0.80 each for die in waffle pack; $0.85 each for
330pF or 1000pF COB; and $0.85 each for 8-pin PDIP or SOIC packages. Samples
and volume production are available today. For more information, contact any
Microchip sales representative.
