ST M24LR04E－R NFC－RFID标签解决方案

ST公司的M24LR04E-R是集成了双路接口的电擦除可编存储器(EEPROM),包括I2C模式的512x8b和RF模式的128x32b RF,同时具有能量采集的模拟输出,以及用户可编程的数字输出和密码保护,主要用作NFC/RFID标签.本文介绍M24LR04E－R主要特性,电路框图, M24LR-DISCOVERY评估板和RF收发器演示板主要特性,电路图,材料清单和PCB元件布局图.

The M24LR04E-R device is a Dynamic NFC/RFID tag IC with a dual-interface, electrically erasable programmable memory (EEPROM). It features an I2C interface and can be operated from a VCCpower supply. It is also a contactless memory powered by the received carrier electromagnetic wave. The M24LR04E-R is organized as 512 × 8 bits in the I2C mode and as 128 × 32 bits in RF mode.

The M24LR04E-R also features an energy harvesting analog output, as well as a user-configurable digital output pin toggling during either RF write in progress or RF busy mode.I2C uses a two-wire serial interface, comprising a bidirectional data line and a clock line. The devices carry a built-in 4-bit device type identifier code (1010) in accordance with the I2C bus definition.
