The MB85RC128 is a 128Kbit FRAM (Ferroelectric Random Access Memory) produced by Fujitsu. FRAM is a non-volatile memory technology that combines the advantages of both RAM and ROM. It offers fast write speeds, high endurance, and low power consumption, making it suitable for a wide range of applications.

Applications:

• Data Logging: Used in industrial data loggers, medical devices, and automotive event recorders for continuous data storage.
• Metering: Employed in smart meters for electricity, water, and gas to store consumption data and meter readings.
• Wearable Devices: Utilized in fitness trackers, smartwatches, and other wearables to store user data and activity logs.
• Medical Equipment: Used in medical devices such as glucose monitors and infusion pumps to store patient data and configuration settings.
• Gaming Devices: Employed in gaming consoles and handheld devices to store game save data and user profiles.

Features:

• Memory Size: 128Kbit (16K x 8) capacity.
• Non-Volatile: Data is retained even when power is removed.
• Fast Write Speed: Offers significantly faster write speeds compared to EEPROM and Flash memory.
• High Endurance: Supports a very high number of write cycles (typically 10 trillion read/write cycles).
• Low Power Consumption: Requires very low power for both read and write operations.
• I2C Interface: Communicates via a standard I2C serial interface.
• Wide Operating Voltage: Operates over a wide voltage range (e.g., 2.7V to 3.6V or 1.8V to 3.6V, depending on the specific version).
• Small Package: Available in compact surface-mount packages such as SOP or DIP.

Benefits:

• Data Retention: Provides reliable data storage even in the absence of power.
• Fast Write Operations: Enables rapid data logging and storage.
• Long Lifespan: High endurance ensures reliable operation over an extended period.
• Energy Efficiency: Low power consumption extends battery life in portable devices.
• Easy Integration: I2C interface simplifies integration with microcontrollers and other systems.
