Description and Introduction

4096K Nonvolatile SRAM The DS1250Y-70 is a nonvolatile static RAM (NV SRAM) manufactured by DALLAS (now part of Maxim Integrated). Here are its key specifications:

- **Memory Size**: 512Kb (64K x 8)
- **Access Time**: 70ns
- **Voltage Supply**: 5V ±10%
- **Data Retention**: 10 years minimum without power
- **Operating Temperature Range**: 0°C to +70°C
- **Package**: 28-pin DIP (Dual In-line Package)
- **Features**: Integrated lithium energy source, real-time clock (RTC), and automatic write protection during power loss
- **Interface**: Parallel (8-bit)

This device combines SRAM with nonvolatile memory technology, ensuring data retention even during power interruptions.
