13.56-MHz Full-Standard Reader IC : Support ISO14443A/B and ISO15693 Felica
The RE41 is a single-chip long-range reader designed for all popular 13.56MHz RFID standard protocols, including ISO14443A, ISO14443B, ISO15693, and JIS-X-6319. 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 RE41 reader also offers a low power consumption mode to optimize energy usage.
