RE31
Multi-Protocol HF Reader IC
13.56-MHz Multi-Standard Reader IC : Support ISO14443A/B and ISO15693
The RE31 is a single-chip long-range reader designed for all popular 13.56MHz RFID standard protocols, including ISO14443A, ISO14443B, and ISO15693. 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 10Mbps and includes on-chip dual 80mA 3.3V 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.
