The “Absolute Maximum Ratings” are those values beyond which
the safety of the device cannot be guaranteed. The device should not be
operated at these limits. The parametric values defined in the Electrical
Characteristics tables are not guaranteed at the absolute maximum rating.
The “Recommended Operating Conditions” table will define the conditions
for actual device operation.

ESD testing conforms to MIL-STD-883, Method 3015.

Note 3:
The specified limits represent “worst case” values for the parameter. Since these values normally occur at the temperature extremes, additional
noise immunity and guardbanding can be achieved by decreasing the allowable system operating ranges. Conditions for testing shown in the tables are cho-
sen to guarantee operation under “worst case” conditions.

三星刚出的旗舰新机Galaxy S III固然不错，但是高昂的价格不是每个人都能承受的起。昨天我们报道了一部山寨版的i9300，而现在该机价格和具体配置已经全部出炉。 这款山寨的Galaxy S III名叫HDC Galaxy S3，其外形甚至UI界面都与原型机异常相似。该机的三围为138×70×9.2mm，配备了一块4.7寸触摸屏，分辨率只有800×480像素。

为了在产品众多、竞争激烈的市场上使产品与众不同，手持设备的制造商们往往把电池寿命和电源管理作为手机、PDA、多媒体播放器、游戏机、其它便携式消费类设备等产品的关键卖点来考虑。用户是从电池寿命这方面来看待电源管理的成效，其实它是多种因素共同作用的结果，这些因素包括 CPU 功能、系统软件、中间件，以及使用户可以在更长的充电或更换电池的间隔时间内享用各自设备的策略。 电源管理范围 任...[详细]
概述： 介绍一种CAN-bus网络与以太网连接，构成一个中型远程监控/数据传输网络的方法。
CAN（Controller Area Network——控制器局域网）是一种由CAN控制器组成的高性能串行数据局域通信网络，是国际上应用最广泛的现场总线之一。它最早由德国Bosch公司于1984年推出，最初用于汽车内部测量与执行部件之间的数据通信。CAN-bus总线模型符合OSI的7层结构...[详细]
