Description and Introduction

2048k Nonvolatile SRAM The DS1249AB-70IND is a nonvolatile static RAM (NV SRAM) manufactured by DALLAS (now part of Maxim Integrated). Below are its key specifications:

- **Memory Size**: 1Mb (128K x 8)  
- **Technology**: Combines SRAM with an integrated lithium energy source for nonvolatility  
- **Access Time**: 70ns  
- **Operating Voltage**: 4.5V to 5.5V  
- **Data Retention**: Minimum 10 years without power  
- **Temperature Range**: Industrial (-40°C to +85°C)  
- **Package**: 32-pin DIP (Dual Inline Package)  
- **Pin Configuration**: JEDEC standard  
- **Write Cycles**: Unlimited (like standard SRAM)  
- **Automatic Power-Fail Protection**: Switches to battery backup when VCC falls below threshold  

This device is designed for applications requiring nonvolatile memory with fast SRAM performance.
