MB85RC256VPNF-G-JNERE1 Memory: Application Field and Working Principle

The MB85RC256VPNF-G-JNERE1 is a serial FRAM (Ferroelectric Random Access Memory) that is meant for various industrial needs. FRAM is a type of non-volatile memory that retains its contents after shutdown and power cycles. Compared to other volatile and non-volatile memory types, serial FRAM (F-RAM) has the advantages of low power, fast write speeds, and infinite endurance. It is typically used in applications that require frequent data storage and retrieval such as data logging, instrumentation, and process control.

The MB85RC256VPNF-G-JNERE1 by Fujitsu is a 256K memory device that utilises the I2C bus and is programmable to operate up to 400kHz. It is the first of its kind to offer write protection for individual pages or 32-bytes of data, allowing for safe and secure storage and retrieval of data. The device also boasts an area configuration setting feature through external resistance, allowing for up to eight partitions (or areas) of data to be held within the same memory device.

The datasheet for the MB85RC256VPNF-G-JNERE1 memory device states that it is suitable for various applications such as data logging in automotive and industrial environments, as well as in portable and/or handheld devices with low power consumption requirements and stringent data security needs. Additionally, the device is ideal for use in medical instruments, process and quality control, and other automation equipment. It can also be used in storage solutions for the industrial internet of things, the automotive industry, and the internet of things.

MB85RC256VPNF-G-JNERE1 Working Principle

The MB85RC256VPNF-G-JNERE1 operates using the Ferroelectric Properties of barium titanate. The memory cells found within the device are made up of ferroelectric materials, sandwiched between two metallic plates. When a voltage is applied to the two plates, the ferroelectric material will take on either a positive or negative polarization depending on the voltage. This polarization state is interpreted as a digital bit, and can be read and written to the device when in use.

The MB85RC256VPNF-G-JNERE1 memory device operates by applying potentials to the electrodes. To read data, the voltage is applied and the polarization of the surface of the ferroelectric material is detected. When the polarization is reversed, it is interpreted as a logic ‘1’, or no polarization is interpreted as a logic ‘0’. To write data, the voltage is applied in the opposite direction to change the polarization of the material.

Due to the Ferroelectric materials in the memory device, it has the capability to hold information for a relatively long time even in the absence of power. The strength of the stored charge is also very high, ensuring data retention for long periods and allowing for fast write speeds. Additionally, the write protect feature and the ability to create up to eight areas of data storage make the MB85RC256VPNF-G-JNERE1 an ideal choice for industrial applications that require secure and reliable data storage and retrieval.

Conclusion

The MB85RC256VPNF-G-JNERE1 serial FRAM is ideal for applications requiring data storage and retrieval in industrial settings. Its low power consumption and fast write speeds means data can be stored and retrieved quickly and reliably. Additionally, the write protect feature and the ability to create up to eight areas of data storage make the MB85RC256VPNF-G-JNERE1 an ideal choice for applications with stringent data security needs. The MB85RC256VPNF-G-JNERE1 is an ideal choice for many data storage and retrieval needs in various industries.
