• M24LR04E-RMC6T/2 Application Field and Working Principle

  The M24LR04E-RMC6T/2 is a type of RFID chip for use in multiple fields due to its wide spectrum of applications. This integrated circuit (IC) includes a built-in 32-byte EEPROM and a 2-pin contactless communication interface, suitable for automatic data collection analysis, transportation management, card access systems, and access control.

  The M24LR04E-RMC6T/2 integrates a 32-byte, 1Kbit EEPROM that can be read or written, with a contactless RF transmission interface that is based on magnetic field coupling principles. The chip operates on a supply voltage of 1.8V to 5.5V and is part of a network that includes connected microcontrollers, RF readers, transponders, and IC cards.

  The M24LR04E-RMC6T/2 provides a fast and efficient way to read and write data from/to any accessibility point. Moreover, the chip enables high-security communication over the network. The chip’s built-in AES encryption ensures that the transmitted data is not accessible by unauthorized persons. All contactless communication operations are performed in compliance with the ISO 15693 standard in terms of data rate, modulation, and coding.

  The M24LR04E-RMC6T/2 chip works on a frequency of 13.56 MHz, with an output power of 0 dBm when the supply voltage is 3V. The chip\'s transponder and reader antenna are designed to have a carrier electronic speed of 1.2 kbits/s.

  The M24LR04E-RMC6T/2 chip consists of two parts: the transponder and the reader. The transponder is a small device that contains the chip and an embedded antenna. The reader is a larger device which contains an embedded antenna and a microcontroller. When the reader sends out a communication request, the transponder detects the magnetic field generated by the reader antennas and changes its communication protocol to receive the request.

  When the transponder receives a request, it responds with an authentication code. Once the reader recognizes the code, it will gain access to the chip\'s embedded EEPROM contents. The data stored in the EEPROM can be accessed and modified with the help of specific commands or API which can be implemented using the microcontroller.

  In conclusion, the M24LR04E-RMC6T/2 chip is a versatile chip for RFID applications, due to its contactless design, its low power consumption, efficient network communication, and its 32-byte1Kbit EEPROM memory. The chip is suitable for a wide range of access control, transport, and monitoring applications.
