【摘要】 将一种新型的非易失性存储器FM31256应用在多因子温室环境检测仪中,使得温室数据掉电后具有10年掉电数据保存期,确保了历史温室因子数据的可靠性存储。该存储器内部集成的实时时钟、低电压复位、看门狗记数器等电路,省去了许多外围芯片和电路,具有小体积多功能的特点,特别适合于温室环境中的便携式智能仪器仪表。更多还原

【Abstract】 A new style FRAM (ferroelectric random access Memory) FM31256 is used in measuring instrument of many factors greenhouse environment,which has 10 years data retention. It has guaranteed dependability memory of historical data of the greenhouse.The RTC (real-time clock),low voltage reset circuit and watchdog timer and so on circuits reduce many peripheral chips and circuits,which has small volume and many functions,especially,is suitable for the portable intellectual instrument and apparatus in the greenhouse environment.更多还原
