MB85RC04V** is a FRAM (Ferroelectric Random Access Memory) device manufactured by **Fujitsu Semiconductor**.

The MB85RC04V is a FRAM (Ferroelectric Random Access Memory) device manufactured by Fujitsu Semiconductor. Below are its key specifications, descriptions, and features:

Specifications:

  • Memory Type: FRAM (Non-volatile)
  • Density: 4 Kbit (512 × 8 bits)
  • Interface: I²C (Two-wire serial interface)
  • Operating Voltage: 2.7V to 3.6V
  • Operating Temperature Range: -40°C to +85°C
  • Write Endurance: 10 trillion (10^13) read/write cycles
  • Data Retention: 10 years (at 85°C)
  • Package Type: 8-pin SOP (Small Outline Package)

Descriptions:

  • The MB85RC04V is a 4 Kbit FRAM that combines the benefits of high-speed read/write operations with non-volatile data storage.
  • Unlike traditional EEPROM or Flash memory, FRAM provides faster write speeds, lower power consumption, and superior endurance.
  • It supports I²C communication (up to 400 kHz) and operates within a 3.3V power supply range.

Features:

  • No Write Delay: Unlike Flash/EEPROM, FRAM does not require a write delay or erase cycle.
  • High-Speed Operation: Supports 400 kHz I²C communication.
  • Low Power Consumption: Ideal for battery-powered applications.
  • High Reliability: 10 trillion read/write cycles and 10-year data retention.
  • Hardware Write Protection: Includes a WP (Write Protect) pin to prevent accidental writes.

This FRAM is commonly used in applications requiring frequent data logging, real-time clock (RTC) backup, and low-power embedded systems.
