Description and Introduction

HIGH SPEED 32K x 8 CMOS EPROM The WS57C256F-55DM is a 256K (32K x 8) CMOS Static RAM manufactured by WSI. Below are its specifications, descriptions, and features:

### **Specifications:**
- **Organization:** 32K x 8  
- **Technology:** CMOS  
- **Access Time:** 55 ns  
- **Operating Voltage:** 5V ±10%  
- **Operating Temperature Range:** Commercial (0°C to +70°C)  
- **Package:** 28-pin DIP (Dual In-line Package)  
- **Pin Count:** 28  
- **Power Dissipation:**  
  - Active: 300 mW (max)  
  - Standby: 30 mW (max)  

### **Descriptions:**
- The WS57C256F-55DM is a high-speed, low-power static RAM designed for applications requiring fast access times and reliable performance.  
- It is compatible with TTL levels and features a fully static operation, eliminating the need for external clocks or refresh cycles.  
- The device is suitable for battery-backed or low-power systems due to its low standby current.  

### **Features:**
- **High-Speed Access Time:** 55 ns  
- **Low Power Consumption:**  
  - Active current: 60 mA (typical)  
  - Standby current: 10 µA (typical)  
- **Fully Static Operation:** No refresh required  
- **TTL-Compatible Inputs and Outputs**  
- **Single 5V Power Supply**  
- **Three-State Outputs**  
- **Industrial Standard Pinout** (JEDEC-compatible)  
- **Reliable Data Retention in Standby Mode**  

This information is based on the manufacturer's datasheet for the WS57C256F-55DM. For detailed electrical characteristics and timing diagrams, refer to the official documentation.
