RE31
Multi-Protocol HF Reader IC
DOWNLOAD DATASHEETThe RE31 is a single-chip long-range reader designed for all popular 13.56 MHz RFID standard protocols, including ISO/IEC 14443 A/B, and ISO/IEC 15693. It features a 64-byte FIFO buffer for efficient data handling, a 256-byte EEPROM for ample storage, and high transmission power for robust communication. The chip supports hi-speed SPI communication up to 10 Mbps and includes on-chip dual 80 mA 3.3 V regulators to stabilize the power supply for both the chip and external components. The RE31 reader also offers a low power consumption mode to optimize energy usage.
