MCRF451 Product details

DESCRIPTION OF DEVICE FEATURES

The MCRF450/451/452/455 is a contactless read/write passive RFID device that is optimized for 13.56 MHz

RF carrier signal. The device needs an external LC resonant circuit to communicate wirelessly with the Interrogator. The device is powered remotely by rectifying an RF signal thatis transmitted from the Interrogator and transmits or updates its contents from memory-based on commands from the Interrogator.



Features

• Contactless read and write with anti-collision algorithm

• 1024 bits (32 blocks) of total memory

• 928 bits (29 blocks) of user programmable memory

• Unique 32-bit tag ID (factory programmed)

• 32 bits for data and 16 bits for CRC per block

• Block write protection

• 70 Kbit/s read data rate (Manchester format)

• Special bit (Fast Read) for fast identification and anti-counterfeit applications (EAS)

• 1-of-16 PPM encoding for writing data

• Interrogator-Talks-First (ITF) or Tag-Talks-First (TTF) operation

• Long range for reading and writing

• High-speed anti-collision algorithm for reading and writing

• Fast and Normal modes for write data speed

• Anti-tearing feature for secure write transactions

• Asynchronous operation for low power consumption and flexible choice of carrier frequency bands

• Internal resonance capacitors (MCRF451/452/ 455)

• Two pad connections for external antenna circuit (MCRF452)

• Three pad connections for external antenna circuit (MCRF450, 451, 455)

• Very low power CMOS design

• Die in waffle pack, wafer, wafer on frame, bumped wafer, COB, PDIP or SOIC package options
