Melexis MLX90129 13.56MHz RFID传感和控制方案

Melexis公司的MLX90129是13.56MHz RFID传感器标签和数据采集器,它把外部电阻型传感器的精密采集链和各种接口组合在一起,能通过ISO15693 RFID前端或SPI端口进行接入和控制,仅需接上13.56MHz调谐天线,它就成为RFID温度计. MLX90129主要用于冷链监视,资产管理和监视,建筑物自动化,以及工业,医疗和住宅区控制与监视.本文介绍了MLX90129主要特性,方框图, RFID温度传感器标签, 数据采集器以及基于MCU的MLX90129应用电路, MLX90129评估板EVB90129主要特性,方框图,详细电路图和材料清单.

MLX90129: 13.56MHZ SENSOR TAG / DATALOGGER IC

The MLX90129 combines a precise acquisition chain for external resistive sensors, with a wide range of interface possibilities.

It can be accessed and controlled through its ISO15693 RFID front-end or via its SPI port.Without any other component than a 13,56MHz tuned antenna, it becomes a RFID thermometer. For measuring others physical quantities, one or two resistive sensors can be connected to make batteryless sensing point. Also, the chip can supply a regulated voltage to the other components of the application. Adding a battery will enable the use of the standalone data logging mode. The sensor output data is stored in the internal 3.5kbits user memory.
