介紹 : ◆低成本設計,單一晶片即可解讀 單、雙或三軌讀卡訊號.
◆精巧設計-4 mm x 5mm 14 pin MLFTM ( QFN) surface mount package
特色 : ◆可處理到三軌訊號,只要將4輸出訊號VDD, VSS, DATA, 及 STROBE接到micro -controller即可
◆Data buffer with Shift-Out
◆抗干擾-配合適切的PCB layout,此ASIC能抗來至PC monitors, cell phones, switching power supplies,等干擾.
◆自動 Gain 控制,卡片讀取從30% - 200% 的 International Standards Organization (ISO) 7811 amplitude standard
