FAQs

What is MB85RS256?

The MB85RS256 is a 256-kbit (32,768 x 8-bit) non-volatile FRAM (Ferroelectric RAM) memory device manufactured by Fujitsu Semiconductor. It combines the non-volatility of ROM with the high-speed read and write performance of RAM, making it suitable for applications requiring frequent read and write operations, such as data logging, metering, and automotive ECUs.

How Does MB85RS256 Work?

The MB85RS256 utilizes ferroelectric technology to store data. Unlike traditional RAM, FRAM does not require a backup power supply to retain stored information, providing non-volatile storage characteristics. The device supports high-speed read and write operations with virtually unlimited endurance and low power consumption.

How Many Pins does MB85RS256 have and What are the Functions of the Pinout Configuration?

The MB85RS256 is available in various package options, including SOP, TSSOP, and DFN. The pinout configuration generally includes:

VDD, VSS: Power supply and ground pins, respectively.
SDA, SCL: Serial interface control pins for I2C communication.
WP: Write protect pin to control write operations.
NC: No connect pin (not internally connected).

What are the Pros and Cons of MB85RS256?

Pros:

Non-Volatile: Retains data without the need for a backup power supply.
High-Speed Operation: Supports fast read and write access times.
Endurance: Offers virtually unlimited read and write cycles for long-term reliability.
Low Power Consumption: Consumes low power, suitable for battery-operated devices.
Compact Packages: Available in various compact package options for space-constrained designs.

Cons:

Cost: FRAM technology may have a higher cost compared to conventional non-volatile memory technologies.
Interface Compatibility: Requires support for I2C interface in the host system.

Are There Any Equivalents/Alternatives to MB85RS256 for Recommendation?

The FM25V02A from Cypress Semiconductor is a 256-kbit serial FRAM memory similar to the MB85RS256.
Alternative non-volatile memory devices include EEPROMs (Electrically Erasable Programmable Read-Only Memory) and flash memories from various manufacturers.
