每天,航空公司都会在全球范围内运送数百万乘客。
作为最安全的交通工具,我在踏上飞机之前从未三思而后行。
一旦我浏览了长长的安全线,我就可以放松,放松,享受运营商提供的船上娱乐。
当船长问“如果有什么我们可以做的让你的航班更愉快,请不要犹豫,”我想打电话按钮并说“加速”!
早在飞机获得飞行认证之前,工程师就会努力工作以确保它能够在A点到B点之间完成,并且在未来几年内不会出现电气或机械问题。
在穿越全球各地的天空时,飞机被宇宙射线轰击,放射性粒子来自地球外部的大气层。
这些粒子穿透其路径上的一切,包括飞机上的电子设备到巴哈马群岛。
但如果我看不到这些颗粒,谁真的在意呢?

你看不到什么可以伤害你
即使我们看不到这些放射性粒子,如果不加以控制,它们会对飞机电子设备产生破坏性影响,从而导致故障甚至完全关闭。
宇宙射线具有足够的能量来改变电子集成电路中的电路元件的状态,导致发生瞬时错误,例如电子存储器设备中的数据损坏,或者CPU的不正确性能,通常被称为“软错误”。
如果被忽视,结果可能是最糟糕的。
幸运的是,像安森美半导体这样的专用集成电路(ASIC)供应商提供了设计解决方案来对抗宇宙射线的电子中断。
成熟的航空航天解决方案
安森美半导体的110nm和180nm数字ASIC工艺节点包括标准单元和SRAM架构,可在电压和温度范围内实现出色的中子测试结果。
此外,增强型基板,冗余和纠错码(ECC)可提供额外的单事件效应(SEE)保护。
这些功能存在于现有的数字ASIC流程中,从而实现了优越的定价,开发和制造周期时间。
凭借ITAR认证,可信认证和QML流程,安森美半导体可以满足您对航空航天应用的所有需求。
中子测试结果
宇宙射线将始终穿透飞行中的飞机。
通过添加ON Semiconductors Rad Hard解决方案,可以管理并几乎消除这些影响。
因此,下次您的航班安全到达目的地时,请感谢飞行员以及帮助指导您的ASIC公司!

Every day, airlines carry millions of passengers around the world. As the safest means of transportation, I never think twice before stepping onto an aircraft. Once I navigate through the long security lines, I am ready to kick back, relax, and enjoy the on-board entertainment the carrier has to offer. When the captain asks “If there is anything we can do to make your flight more enjoyable don’t hesitate to ask,” I want to ring my call button and say “speed up”!
Long before an aircraft is certified for flight, engineers work diligently to ensure that it will make it from point A to point B with no electrical or mechanical problems for years to come. While traversing the skies around the globe, airplanes are bombarded by cosmic rays, radioactive particles that originate from outside earth’s atmosphere. These particles penetrate everything in its path, including the electronics onboard your plane to the Bahamas. But if I can’t see these particles, who really cares?

What You Don’t See Can Hurt You
Even though we can’t see these radioactive particles, if left unchecked they can have devastating effects on airplane electronics which can result in glitches or even complete shutdown. Cosmic rays have sufficient energy to alter the states of circuit components in electronic integrated circuits, causing transient errors to occur, such as corrupted data in electronic memory devices, or incorrect performance of CPUs, often referred to as "soft errors". If ignored, the outcome could be dire at best. Fortunately, Application Specific Integrated Circuit (ASIC) suppliers like ON Semiconductor have design solutions to combat electronic disruptions from cosmic rays.
Proven Aerospace Solutions
ON Semiconductor’s 110nm and 180nm digital ASIC process nodes include standard cell and SRAM architectures that achieve excellent neutron test results across voltage and temperature. In addition, enhanced substrates, redundancy and error correction code (ECC) provide additional Single Event Effects (SEE) protection. These capabilities reside in the existing digital ASIC flows resulting in superior pricing, development and manufacturing cycle times. With ITAR certification, Trusted Accreditation and QML flows, ON Semiconductor can meet all your needs for aerospace applications.
Neutron Test Results
Cosmic rays will always penetrate in-flight aircraft. By adding ON Semiconductors Rad Hard solutions these effects can be managed and nearly eliminated. So the next time your flight arrives safe at your destination, thank the pilot, and the ASIC company that helped guide you there!
