ABI Research最近评选并公布了全球超高频无源和高频无源 RFID芯片的前十大制造商。 前十大超高频无源芯片制造商是： 前十大高频无源芯片制造商是： 超高频的得奖名单并不出人意外，因为实际上似乎总是前三家公司获得大订单。ABI分析家 Mike Liard称，ABI很容易就评选出 Alien、Avery,和 Raflatac为全球...[详细]
便携式医疗设备的特殊性决定了它们应该是对用户友好的、必须工作在无菌环境下，并且空间占用小、耗能低。 同时，便携式医疗设备还需要足够的计算能力以便处理医疗数据，能够连接到无线或有线接口以便记录和发送数据。从设计人员的角度考虑，上述需求需要低功耗的单片机（MCU）和数字信号控制器（Digital Signal Controller，DSC）。 正是有了嵌入式处理器，设计人员才有可能设...[详细]
