MC14468芯片技术攻关与解密案例

时间:2012-07-12 09:09:55

世纪芯较早就已经顺利取得技术突破,成功破解多款典型IC芯片,而由于解密难度大、周期长,使得解密成本及费用相对较高。为此,世纪芯又专门组织技术力量进行该系列芯片低成本解密方案研究,使针对MC14468芯片解密的技术更为成熟,解密成本更低,为客户实现更大经济效益。这里,我们仅以MC14468芯片为例,针对其性能特征做简单介绍:
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.
·Ionization Type with On–Chip FET Input Comparator
·Piezoelectric Horn Driver
·Guard Outputs on Both Sides of Detect Input
·Input–Production Diodes on the Detect Input
·Low–Battery Trip Point, Internally Set, can be Altered Via External Resistor
·Detect Threshold, Internally Set, can be Altered Via External Resistor
·Pulse Testing for Low Battery Uses LED for Battery Loading
·Comparator Output for Detect
·Internal Reverse Battery Protection
·Strobe Output for External Trim Resistors
·I/O Pin Allows Up to 40 Units to be Connected for Common Signaling
·Power–On Reset Prevents False Alarms on Battery Change
