GXSC ferroelectric memory GX85RS128 replaces MB85RS128/FM25V01 for application in programmable AC power supply

Programmable AC power supply is a key equipment in fields such as electronic testing, new energy, and intelligent manufacturing. Its performance depends on high-speed storage and precise retrieval of voltage and current waveform data. This type of device requires frequent writing of user configuration parameters (such as output voltage, frequency, waveform type) and waveform sampling data, and high-frequency reading during output. At the same time, the data is required to be saved for a long time after power failure.

The non-volatile, high-speed read/write, and high erase/write capabilities of ferroelectric memory fully meet the storage requirements of programmable AC power supply. The GXSC ferroelectric memory GX85RS128 is highly compatible with imported devices MB85RS128 (Fujitsu) and FM25V01 (Cypress) in terms of capacity, interface, and performance, providing a cost-effective domestic alternative to programmable AC power supplies.

From the above comparison, it can be seen that the GXSC ferroelectric memory GX85RS128 can replace Fujitsu MB85RS128/Cypress FM25V01 with PIN TO PIN. GX85RS128 adopts a standard SPI interface and is fully compatible with MB85RS128/FM25V01. The chip does not require large-scale hardware circuit modifications during the replacement process, which can reduce the development cost of the solution.

The GX85RS128 storage unit can support up to 1e6 read/write operations, which is much more durable than many similar storage devices. The high number of read/write operations ensures the stability and persistence of data storage. It supports 40MHz high-speed read commands and can respond quickly when handling emergency data requests with AC power, reducing data read latency and improving overall device efficiency. Compared with MB85RS128/FM25V01, GX85RS128 is also comparable in read and write performance.

The design of programmable AC power supply should take into account the power consumption requirements under different working modes. The use of low-power storage chips can effectively reduce overall energy consumption, and the power management circuit should have fast response speed. To ensure data integrity, stable voltage output is required, and the ripple factor of the power supply should be controlled within a very small range. In the design, electromagnetic compatibility should be considered to avoid interference, and the low-power design of GX85RS128 is particularly outstanding compared to MB85RS128/FM25V01. Its maximum power consumption is only 5mA, and the standby current is as low as 7 μ A, which can reduce the frequency of device charging or battery replacement.
