Product Overview

ANT4-M24LR-A antenna reference board is a ready to use PCB that includes two M24LR64-R dual interface EEPROM ICs connected to a 13.56MHz etched RF antenna on one side, and to an I2C bus on the other side. The M24LR64-R is organized as 8192 × 8 bits in the I2C mode and as 2048 × 32 bits in the ISO 15693 and ISO 18000-3 mode 1 RF mode. It can be operated from a VCC power supply and is also a contactless memory powered by the received carrier electromagnetic wave. Both interfaces are widely used industry standards. The design principle of the M24LR64-R antenna is very simple, the external antenna inductance that needs to be designed on board the PCB should match the M24LR64-R internal tuning capacitance in order to create a circuit resonating at 13.56MHz. Board allows system designers to evaluate the M24LR64-R IC in multibank configuration since the board is seen as a 128Kbit memory split into 2 banks of equal size.
  • Two wire I2C serial interface supports 400KHz protocol
  • 45mm x 75mm 13.56MHz inductive antenna etched on the PCB
  • Single password protection in I2C mode
  • Multiple password protection in RF mode
  • Enhanced ESD/latch up protection
  • 64bit unique identifier
  • More than 40 year data retention
  • More than 1 million write cycles
