The MCRF202 is a passive Radio Frequency Identification (RFID) IC device with an external sensor Input that provides an RF interface for reading the contents of a user memory array. The MCRF202 is specially designed to detect the logic state of an external sensor, and alter its data transmissions, based on the condition of the sensor input. A logic 1 at the sensor input results in normal operation, a logic 0 at the sensor inputs causes the entire data stream to be inverted. In this way, a reader can simultaneously obtain the tag's ID number and the state of an external switch or other sensor. 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 transmitted. Code length, modulation option, encoding option, and bit rate is set at the factory to fit the needs of specific applications. 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 prior to shipment.
