Memory is critical when it comes to the proper functioning of computers, other digital devices, and embedded systems. As technology advancements come, memory devices have become smaller, more efficient, and more reliable. MB85RS256APNF-G-JNE1 is an example of a cutting-edge memory device that is ideal for high-end applications. This article will discuss the MB85RS256APNF-G-JNE1 application field and its working principle.

Application Field

The MB85RS256APNF-G-JNE1 is a FRAM (Ferroelectric Random-Access Memory) chip that is part of the 512Kbit Serial FRAM Memory Series from Fujitsu. This series has been designed for a variety of applications, including Factory Automation, Security and Autom counter readings, Medical Devices, POS terminals and Intelligent Measuring Instruments. The MB85RS256APNF-G-JNE1 chips can also be used in those applications that require reliable non-volatile data storage and AI and fuzzy logic applications when combined with a microcontroller.

The MB85RS256APNF-G-JNE1 has a data retention of more than 10 years and an unlimited write cycles endurance so it can handle data logging and similar jobs. In addition, it features high-speed communication that allows it to be employed in high-end applications.

Working Principle

The MB85RS256APNF-G-JNE1 is a low-power Serial FRAM device that operates at speeds of up to 100 MHz. It has a 512K-bits of FRAM non-volatile memory that is organized in 32 blocks of 16K-bits each. The MB85RS256APNF-G-JNE1 is controlled by a one-wire serial interface that allows for both read and write operations. The FRAM memory is divided into two segments. The upper half is the regi file, which can be read or written by the user. The lower half is used for data storage and is protected from unauthorized access.

The regi file can be divided in up to 19 pages, each containing configurations that enable the chip to operate in different modes. The page 0 contains the configuration registers of the chip, which are used by the chip to enable its functions. Other pages are user-defined, which enable the user to store data, configure the chip and so on.

The MB85RS256APNF-G-JNE1 is powered with a supply voltage of 3V, 3.3V, 1.8V and 5.0V. It also has an integrated voltage regulator that allows the use of an external voltage supply of up to 5.5V. The chip has an excellent power efficiency of 1mW/MHz, ensuring a low-power operation even when used at high speeds.

Conclusion

The Fujitsu MB85RS256APNF-G-JNE1 is a cutting-edge FRAM device that offers high speeds, unlimited write cycles, data retention time and a host of other features. Its low-power operation and integrated voltage regulator make it an ideal chip for use in a variety of applications, including Factory Automation, Security and Autom counter readings, Medical Devices, POS terminals and Intelligent Measuring Instruments. This device has a number of advantages over other types of memory devices, making it a versatile and reliable option for storing data.
