摘　　要：传统只读射频卡读卡器的设计一般采用U2270B或P4095读写基站芯片加MCU模式,其成本高、功耗大。本文介绍一种仅采用一片89C2051加少量普通元件构成的读卡器电路以及独特的等时间间隔指令分组并行处理的程序设计方案,电路简单、功耗小、成本低。The traditional approach of designing RFID reader is by an additive with a MCU ,and thus it has the shortage of high cost and high power. This paper electro-circuit only using a 89C2051 with a few common electronic components and uniform intervals. Therefore, the new RFID reader is a simple circuit with advantages U2270 or P4095,a read/write base station IC, presents a new design by means of a reading the technology of dividing instruction group in of lower cost and lower power.
