Description and Introduction

256K x 8 HIGH-SPEED CMOS STATIC RAM The IS61LV2568L-8K is a high-speed 256K x 8 (2-Mbit) static RAM (SRAM) manufactured by ISSI (Integrated Silicon Solution, Inc.).  

### **Specifications:**  
- **Organization:** 256K x 8 (2 Mbit)  
- **Voltage Supply:** 3.3V (±10%)  
- **Access Time:** 8 ns  
- **Operating Current:** 70 mA (typical)  
- **Standby Current:** 5 mA (typical)  
- **Package:** 32-pin TSOP (Type I)  
- **Operating Temperature Range:** Commercial (0°C to +70°C) and Industrial (-40°C to +85°C)  
- **Interface:** Asynchronous  
- **Tri-State Outputs:** Yes  
- **Auto Power-Down:** Supported  

### **Descriptions and Features:**  
- **High-Speed Operation:** 8 ns access time for fast read/write operations.  
- **Low Power Consumption:** Features standby and operating modes to reduce power usage.  
- **Wide Voltage Range:** Operates at 3.3V with tolerance for industrial applications.  
- **Asynchronous Operation:** No clock required for read/write operations.  
- **CMOS Technology:** Ensures low power and high performance.  
- **Industrial-Grade Options:** Available for extended temperature ranges.  
- **Compatibility:** Directly replaces similar-density SRAMs from other manufacturers.  

This SRAM is commonly used in networking, telecommunications, and embedded systems requiring fast, low-power memory.
