Note 4:
The write cycle time (t
WR
) is the time from a valid stop condition of a write sequence to the end of the internal erase/program cycle. During the write cycle,
the FM24C128 bus interface circuits are disabled, SDA is allowed to remain high per the bus-level pull-up resistor, and the device does not respond to its slave
1、引言 汽车污染是当前人们最为关心和急需解决的重要课题之一。作为汽车排气污染物的检测的重要方法,简易瞬态工况法（VMAS法，IG法）可以统计排放总质量，监控车辆的真实排放情况，设备成本不高，测量比较准确，与新车认证检测结果具有相关性，可以检测NO相关因子等一系列优点，成为人们研究的热点。VMAS（Vehicle Mass Analysis System）检测方法在美国和欧洲都有很好的应用基础，...[详细]
国际半导体设备材料产业协会（SEMI）昨（10）日公布半导体设备资本支出的年中预测报告（SEMI Capital Equipment Forecast），预估2012年全球半导体设备营收规模将达到423.8亿美元，2013年将成长至467.1亿美元。
受惠平板电脑、智慧型手机与行动装置等消费性电子商品亮丽表现，半导体设备的采购需求仍将持续。SEMI在报告中指出，2011年半...[详细]
