Overview

The MB85RC64TAPNF-G-BDERE1 is a 64Kbit (8KB) non-volatile Ferroelectric RAM (FRAM) memory IC. It offers fast access times comparable to SRAM, while retaining data without power like EEPROM or Flash. This device communicates via an I2C interface, supporting clock frequencies up to 3.4 MHz.

Why Choose This Part

This FRAM offers excellent endurance with virtually unlimited write cycles, surpassing traditional EEPROM and Flash. It combines non-volatility with high-speed random access, similar to SRAM, eliminating the need for battery backup in many applications. Its low operating current of 0.17mA (Typ @3.4MHz) and standby current of 8uA make it suitable for power-sensitive designs.

Applications

Industrial Control Systems
Storing configuration parameters, event logs, and critical operational data that must persist through power cycles in industrial equipment.
Smart Meters
Recording consumption data, tamper events, and billing information in utility meters, benefiting from FRAM's high endurance and non-volatility.
Medical Devices
Saving patient settings, calibration data, and usage statistics in portable and implantable medical devices where data integrity and low power are crucial.
Data Loggers
Capturing sensor readings or system states at regular intervals, providing reliable storage with low power consumption for battery-powered applications.
Wearable Technology
Maintaining user preferences, activity data, and device states in wearables, utilizing FRAM's fast write speeds and low energy requirements.

Getting Started

To get started with the MB85RC64TAPNF-G-BDERE1, interface it with any microcontroller supporting I2C communication. Most embedded development boards (e.g., Arduino, Raspberry Pi, STM32 Nucleo boards) have I2C peripherals. Example code and libraries for I2C FRAMs are widely available, allowing quick integration into projects.

Also Consider

FM24CL16B-GTR Cypress Semiconductor Corp - Offering 16Kbit of FRAM, this alternative provides a slightly larger memory capacity with the same I2C interface and non-volatile benefits.
CAT24C64WI-GT3 ON Semiconductor - For cost-sensitive applications where extremely high write endurance is not critical, a 64Kbit EEPROM like this offers non-volatile storage with an I2C interface.
