Abstract:

In order to meet the requirements of the RFID reader in different applications systems,this study develops a handheld RFID reader which has the MSP430F149 MCU as the core and has the embedded Ethernet network interface.This paper introduces the design method for the network interface in RFID reader which is constituted of MCU and the RTL8139 Ethernet controller,and achieves the handheld RFID reader's access to the internet network for data communications.

Key words: MSP430 MCU;RFID reader;network interface
