  - Automatic power-fail chip deselect  
  - Real-time clock (RTC) with century byte  
  - Battery low flag  

### **Descriptions:**  
- Combines SRAM with a non-volatile element for data retention during power loss.  
- Uses an internal lithium cell to maintain data for over 10 years.  
- Includes a real-time clock (RTC) with BCD-coded timekeeping (seconds, minutes, hours, day, date, month, year).  

### **Features:**  
- **Non-volatile Storage:** Retains data without external power.  
- **Automatic Write Protection:** Prevents data corruption during power transitions.  
- **Low Power Consumption:** Optimized for battery-backed applications.  
- **Industrial Temperature Range:** Suitable for harsh environments.  
- **JEDEC-compliant Pinout:** Ensures compatibility with standard SRAMs.
