The FM25V20-G is a non-volatile, low-power FRAM (Ferroelectric Random Access Memory) chip which can permanently store data even when power is turned off. This versatile, low-power and high-speed memory chip is widely used in embedded memory applications, including real-time clocks and transaction logs, and is an effective alternative to many existing EEPROM (Electrically Erasable Programmable ROM) memory chips. This article provides an overview of the FM25V20-G’s application field and working principle.Application Field The FM25V20-G FRAM chip is widely used in various embedded memory applications. It is an ideal memory device for cost and power sensitive embedded systems and designs requiring high reliability and long life. Its feature set makes the FM25V20-G the perfect choice in applications such as industrial automation, GPS receivers, and other resource-constrained applications. In addition, its ease of integration and low power consumption make it a great choice for consumer, medical, automotive, and industrial applications.The FM25V20-G is also used in systems with high demands for performance, reliability, and low power, such as medical and industrial automation. Additionally, its SPI protocol makes it an ideal embedded memory device for applications with strict constraints on board space, making it a cost-effective choice.Working Principle The working principle of the FM25V20-G FRAM chip is based on a ferroelectric process, which allows it to store data without a power supply. This is achieved by using a thin layer of ferroelectric material between two electrodes. The voltage applied to the electrodes creates a very weak electric field, which polarizes the ferroelectric material and allows it to store data.When writing data to the FM25V20-G, the user can set the voltage to any range between 0 V and 5 V, depending on the desired signal strength. At the same time, when reading data from the FM25V20-G, a voltage signal is read and converted into a read value.In addition to its basic read/write operations, the FM25V20-G also features a power-down safety register and an extended data protection register. The power-down safety register allows the chip to maintain data when power is turned off, while the extended data protection register prevents inadvertent erasing of valid data.ConclusionThe FM25V20-G FRAM chip is a versatile, low-power, and high-speed memory chip that is widely used in embedded memory applications. Its low power consumption and ease of integration make it a great choice for resource-constrained designs. Additionally, its ferroelectric process allows it to store data without a power supply, enabling it to perform both write and read operations with relative ease. Finally, the FM25V20-G also includes a power-down safety register and an extended data protection register, both of which provide an additional layer of reliability and security.
