世纪芯在芯片解密业界长期致力于各类高难度IC解密方案开发,勇于挑战行业内的技术难题。对于MC14468系列疑难型解密芯片,我们的专业工程师专门自主开发了单片机程序读取工具,这就解决了困扰各类技术工程师芯片程序无法读取的问题。
The MC14468, when used with an ionization chamber and a small number of external components, will detect smoke. When smoke is sensed, an alarm is sounded via an external piezoelectric transducer and internal drivers. This circuit is designed to operate in smoke detector systems that comply with UL217 and UL268 specifications.
