Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these
or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability.

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]
