Description and Introduction

256K-bits FRAM LSI using the ferroelectric process and CMOS process technologies The MB85R256G is a FRAM (Ferroelectric Random Access Memory) device manufactured by Fujitsu. Here are the key specifications, descriptions, and features:

### **Specifications:**  
- **Memory Size:** 256 Kbit (32 K × 8 bits)  
- **Interface:** SPI (Serial Peripheral Interface)  
- **Operating Voltage:** 2.7V to 3.6V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Write Endurance:** 10 trillion read/write cycles  
- **Data Retention:** 10 years (at 85°C)  
- **Package:** 8-pin SOP (Small Outline Package)  

### **Descriptions:**  
- Non-volatile memory with high-speed read/write performance.  
- Combines the benefits of RAM (fast access, unlimited endurance) and Flash (non-volatility).  
- No need for a backup battery due to non-volatile storage.  

### **Features:**  
- **High-Speed Operation:** Comparable to SRAM, with no write delays.  
- **Low Power Consumption:** Consumes less power compared to EEPROM/Flash.  
- **SPI Interface:** Supports up to 25 MHz clock frequency.  
- **Hardware Write Protection:** Protects against accidental writes.  
- **RoHS Compliant:** Lead-free and environmentally friendly.  

This FRAM is commonly used in applications requiring frequent data logging, real-time data storage, and low-power operation.
