1 / 24 page  2003 Microchip Technology Inc. DS21267F-page 1 MCRF250 Features Factory programming and memory serialization (SQTP SM) • Anti-collision feature to read multiple tags in the same RF field. • One-time contactless programmable (developer kit only) • Read-only data transmission after programming • 96 or 128 bits of One-Time Programmable (OTP) user memory (also supports 48- and 64-bit protocols) • Typical operation frequency: 100 kHz-400 kHz • Ultra low-power operation (5 µA @ VCC = 2V) • Modulation options: - ASK, FSK, PSK • Data Encoding options: - NRZ Direct, Differential Biphase, Manchester Biphase • Die, wafer, COB or SOIC package options • Factory programming options Applications • Access control and time attendance • Security systems • Animal tagging • Product identification • Industrial tagging • Inventory control • Multiple item tagging Package Type Description The MCRF250 is equipped with an anti-collision feature that allows multiple tags in the same field to be read simultaneously. This revolutionary feature eliminates the issue of data corruption due to simultaneous transmissions from multiple tags. The MCRF250 is a passive Radio Frequency Identifi- cation (RFID) device for low frequency applications (100 kHz-400 kHz). The device is powered by rectifying an incoming RF signal from a reader interrogator. The device requires an external LC resonant circuit to receive the incoming energizing signal and to send data. The device develops a sufficient DC voltage for operation when it’s external coil voltage reaches approximately 10 VPP. This device has a total of 128 bits of user programma- ble 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 MCRF250 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.
