† NOTICE: Stresses above those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress rating only and functional operation of the device at those or any other conditions above those indicated in the operational listings of this specification is not implied. Exposure to maximum rating conditions for extended periods may affect device reliability.

The MCRF200 is a passive Radio Frequency Identification (RFID) device for low-frequency applications (100 kHz-400 kHz). 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 MCRF200 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.
