Description and Introduction

262,144-WORD BY 16 BIT STATIC RAM The part **TC554161FTL-70L** is manufactured by **TOSHIBA**. Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Type:** SRAM (Static Random Access Memory)  
- **Density:** 4Mbit (512K words × 8 bits)  
- **Speed:** 70ns access time  
- **Voltage Supply:** 5V ±10%  
- **Operating Temperature Range:** Commercial (0°C to +70°C)  
- **Package:** 32-pin TSOP (Thin Small Outline Package)  
- **Organization:** 512K × 8  
- **Standby Current:** Low power consumption in standby mode  

### **Descriptions and Features:**  
- **High-Speed Operation:** 70ns access time suitable for high-performance applications.  
- **Low Power Consumption:** Optimized for power-sensitive designs.  
- **Wide Voltage Range:** Operates at 5V with a tolerance of ±10%.  
- **TSOP Package:** Compact and surface-mountable for space-constrained applications.  
- **Asynchronous Operation:** No clock required for read/write operations.  
- **Industrial Standard Pinout:** Compatible with other similar-density SRAMs.  
- **Data Retention:** Maintains data without refresh cycles.  

This SRAM is commonly used in embedded systems, networking equipment, and other applications requiring fast, non-volatile memory.
