Replace MB85RS128 and FM25V01, ferroelectric memory GX85RS128 voltage monitor application program

Voltage monitor is a single-chip computer as the core of the grid voltage quality monitoring and statistical instruments, can be read into the voltage signal conversion process, under the synchronization control of the clock, automatic statistics of the data, and the statistical results will be stored so that the user needs to make selective output. Support three-way grid voltage signal acquisition, display and classification statistics, can realize the voltage data statistics summary, report generation and rapid reporting and a series of work.

The voltage monitor can accurately and real-time measure the true RMS value of various voltage waveforms. Its data storage chip adopts domestic ferroelectric memory GX85RS128, which has the characteristics of high-speed writing, ultra-low power consumption and long-time data preservation during power failure. Its operating frequency is up to 25MHz and supports 40MHz high-speed read command, which can quickly store these data into the memory.

In addition, the GX85RS128‘s non-volatile features allow the data stored in the ferroelectric memory to be retained even in the event of a sudden failure of the tester that results in an interruption of the power supply. This facilitates fault analysis and data recovery.
