Description and Introduction

SILICON GATE CMOS 32,768 WORD X 8 BIT STATIC RAM The TC55257BPL-10 is a 262,144-bit high-speed static RAM (SRAM) manufactured by Toshiba. Below are the specifications, descriptions, and features based on the available knowledge:

### **Specifications:**
- **Organization:** 32K x 8 bits  
- **Operating Voltage:** 5V ±10%  
- **Access Time:** 10 ns  
- **Operating Temperature Range:** 0°C to +70°C  
- **Package Type:** 28-pin Plastic DIP (Dual In-line Package)  
- **Power Consumption:**  
  - Active: 275 mW (typical)  
  - Standby: 27.5 mW (typical)  

### **Descriptions:**
- The TC55257BPL-10 is a high-performance CMOS static RAM designed for applications requiring fast access times and low power consumption.  
- It is compatible with TTL levels and features a fully static operation, meaning no clock or refresh is required.  
- The device is suitable for use in cache memory, battery-backed applications, and other high-speed memory systems.  

### **Features:**
- **High-Speed Operation:** 10 ns access time.  
- **Low Power Consumption:** CMOS technology ensures low active and standby power.  
- **TTL Compatibility:** Inputs and outputs are TTL-compatible.  
- **Fully Static Design:** No refresh or clock required.  
- **Tri-State Output:** Allows for bus-oriented applications.  
- **Single 5V Power Supply:** Simplifies system design.
