2 / 24 page MCRF200 DS21219H-page 2 2003 Microchip Technology Inc. Block Diagram The configuration register includes options for commu- nication protocol (ASK, FSK, PSK), data encoding method, data rate, and data length.These options are specified by customer and factory programmed during assembly. Because of its many choices of configuration options, the device can be easily used as an alternative or second source for most of the existing low frequency passive RFID devices available today. The device has a modulation transistor between the two antenna connections (VA and VB). The modulation transistor damps or undamps the coil voltage when it sends data. The variation of coil voltage controlled by the modulation transistor results in a perturbation of voltage in reader antenna coil. By monitoring the changes in reader coil voltage, the data transmitted from the device can be reconstructed. The device is available in die, wafer, Chip-on-Board (COB) modules, PDIP, or SOIC packages. Factory programming and memory serialization (SQTP) are also available upon request. See TB023 for more information on contact programming support. The DV103001 developer’s kit includes Contactless Programmer, ASK, FSK, PSK reference readers, and reference design guide. The reference design guide includes schematics for readers and contactless programmer as well as in-depth document for antenna circuit designs.
