The MB85RC16 is a FRAM (Ferroelectric Random Access Memory) device manufactured by Fujitsu.

Specifications:

• Memory Type: Non-volatile FRAM
• Density: 16 Kbit (2 K × 8 bits)
• Interface: I²C (Two-wire serial interface)
• Operating Voltage: 2.7 V to 5.5 V
• 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 Options: SOP-8, DIP-8

Descriptions:

• The MB85RC16 is a high-reliability, low-power FRAM that combines the benefits of RAM (fast read/write, high endurance) with non-volatile data storage.
• Unlike EEPROM or Flash, it does not require a write delay, making it ideal for real-time data logging and frequent updates.
• It supports I²C communication (up to 400 kHz in Fast Mode).

Features:

• Fast Write Speed: No write delays (unlike EEPROM/Flash).
• High Endurance: 10 trillion read/write cycles.
• Low Power Consumption: No charge pump needed for writes.
• Non-Volatile: Retains data without power.
• Industrial Temperature Range: Suitable for harsh environments.
• Hardware Write Protection: Supports WP (Write Protect) pin for data security.

This device is commonly used in applications requiring frequent data writes, such as industrial systems, metering, automotive, and IoT devices.
