The device is powered by rectifying an incoming RF signal from the reader. The device requires an external LC resonant circuit to receive the incoming RF signal and to send data. The device develops a sufficient DC voltage for operation when its external coil voltage reaches approximately 10 VPP. This device has a total of 128 bits of user programmable memory and an additional 12 bits in its configuration register. The user can manually program the 128 bits of user memory by using a contactless programmer in a microID developer kit such as DV103001 or PG103001. However, in production volume the MCRF200 is programmed at the factory (Microchip SQTP – see Technical Bulletin TB023). The device is a One-Time Programmable (OTP) integrated circuit and operates as a read-only device after programming. Application • Low-cost alternative for existing low-frequency RFID devices • Access control and time attendance • Security systems • Animal tagging • Product identification • Industrial tagging • Inventory control RF Signal Reader Data MCRF200  2003 Microchip Technology Inc. DS21219H-page 1 MCRF200 Block Diagram Modulation Control Data Modulation Circuit Coil Connections Clock Generator VCC Rectifier VSS Row Decode Memory Array Counter Column Decode The configuration register includes options for communication 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. DS21219H-page 2  2003 Microchip Technology Inc.
