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.

Highlight Features

  • Support ISO14443A/B, all bit rates
  • Support ISO15693, all modes
  • Modulation index adjustable by software
  • Outstanding read range with maximum driving current up to
    • 300mA @5V TVDD
    • 400mA @7V TVDD
  • Wide operating voltage for Tx from 2.7 to 7.0 V

Interface and Peripheral

  • SPI Interface up to 10 Mbps
  • 64-byte send and receive FIFO-buffer
  • 64-byte addressing user-configurable registers
  • 256-bytes EEPROM
