Description and Introduction

HIGH SPEED 32K x 8 CMOS EPROM The WS57C256F-70DMB is a 256K (32K x 8) CMOS Static RAM (SRAM) manufactured by WSI (WaferScale Integration). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Organization:** 32K x 8 (256Kbit)  
- **Technology:** CMOS  
- **Access Time:** 70ns  
- **Operating Voltage:** 5V ±10%  
- **Operating Temperature Range:** Commercial (0°C to +70°C) or Industrial (-40°C to +85°C)  
- **Package:** 28-pin DIP (Dual In-line Package)  
- **Power Consumption:**  
  - Active: ~200mW (typical)  
  - Standby: ~20mW (typical)  

### **Descriptions & Features:**
- **High-Speed Operation:** 70ns access time for fast read/write operations.  
- **Low Power Consumption:** CMOS technology ensures low power in both active and standby modes.  
- **Fully Static Design:** No refresh cycles required.  
- **TTL-Compatible Inputs/Outputs:** Ensures compatibility with standard logic levels.  
- **Tri-State Outputs:** Allows bus sharing in multi-device systems.  
- **Wide Operating Voltage Range:** 4.5V to 5.5V.  
- **Reliable Data Retention:** Maintains data integrity with minimal standby current.  
- **Industrial-Grade Options:** Available for extended temperature range applications.  

This SRAM is commonly used in embedded systems, industrial controls, telecommunications, and other applications requiring fast, low-power memory.
