Description and Introduction

1024K Nonvolatile SRAM The DS1245Y-100 is a nonvolatile static RAM (NV SRAM) manufactured by DALLAS (now part of Maxim Integrated). Here are its key specifications:

- **Memory Size**: 1,048,576 bits (128K x 8)
- **Nonvolatile Storage**: Integrates SRAM with a built-in lithium energy source and control circuitry for data retention without power.
- **Data Retention**: Minimum 10 years without power.
- **Access Time**: 100 ns.
- **Operating Voltage**: 4.5V to 5.5V.
- **Operating Temperature Range**: 0°C to +70°C (commercial grade).
- **Package**: 32-pin DIP (Dual In-line Package).
- **Pin Compatibility**: JEDEC standard pinout for easy replacement of existing SRAMs.
- **Write Protection**: Includes an early power-fail warning circuit to protect data during power loss.
- **Unlimited Write Cycles**: Unlike EEPROM or Flash, it supports unlimited read/write cycles.

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