Description and Introduction

8,192 WORD X 8 BIT CMOS STATIC RAM The TC5564AFL-20 is a high-speed 8K x 8-bit static RAM (SRAM) manufactured by Toshiba. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Organization:** 8K x 8-bit (65,536 bits)  
- **Access Time:** 20 ns  
- **Operating Voltage:** 5V ±10%  
- **Operating Temperature Range:** Commercial (0°C to +70°C) or Industrial (-40°C to +85°C)  
- **Package:** 28-pin SOP (Small Outline Package)  
- **Power Consumption:**  
  - Active: 275 mW (max)  
  - Standby: 27.5 mW (max)  

### **Descriptions:**
- **Type:** High-speed CMOS static RAM  
- **Pin Configuration:** Compatible with industry-standard 8K x 8 SRAMs  
- **Data Retention:** Guaranteed in standby mode with reduced voltage (2V min)  

### **Features:**
- **High-Speed Operation:** 20 ns access time  
- **Low Power Consumption:**  
  - CMOS technology for reduced power usage  
  - Battery backup capability  
- **Fully Static Operation:** No clock or refresh required  
- **Tri-State Output:** Allows direct bus connection  
- **TTL-Compatible Inputs/Outputs:** Ensures easy interfacing  
- **Single 5V Power Supply:** Simplifies system design  

This SRAM is designed for applications requiring fast, reliable memory access, such as embedded systems, industrial controls, and telecommunications equipment.
