ST M24LR64-R 13.56 MHz双接口EEPROM开发方案
ST公司的 M24LR64-R是无线存储器，具有口令保护的64Kb EEPROM以及400kHz I2C串行总线和13.56MHz ISO 15693 RF协议的 双接口的64Kb EEPROM，可实现智能手机的近场通信（NFC）。单电源1.8V-5.5V工作，64kb EEPROM分成I2C模式的8192B和RF模式的2048x32b，无接触接口和ISO 15693与ISO 18000-3 mode 1兼容，载波频率13.56 MHz ±7k Hz，广泛用于工业和消费类电子产品。本文介绍了M24LR64-R 主要特性，方框图，M24LR64-R单片和多组合参考设计以及双接口EEPROM开发套件主要特性。
The M24LR64-R device is a dual-interface, electrically erasable programmable memory(EEPROM). It features an I2C interface and can be operated from a VCC power supply. It is also a contactless memory powered by the received carrier electromagnetic wave.
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.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.
