### **Specifications:**
- **Density:** 262,144 words × 8 bits (256K × 8)  
- **Operating Voltage:** 5V ± 10%  
- **Access Time:** 55 ns  
- **Operating Current:** 70 mA (max)  
- **Standby Current:** 10 µA (max, CMOS level)  
- **Package:** 28-pin TSOP (Thin Small Outline Package)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Organization:** 256K × 8 bits  

### **Descriptions:**
- The TC55257DFTL-55L is a low-power, high-performance CMOS SRAM designed for applications requiring fast access times and low power consumption.  
- It is commonly used in embedded systems, networking equipment, and industrial applications.  
- The device features a fully static operation, meaning no clock or refresh is required to retain data.  

### **Features:**
- **High-Speed Access:** 55 ns access time.  
- **Low Power Consumption:**  
  - Operating current: 70 mA (max).  
  - Standby current: 10 µA (max, CMOS level).  
- **Wide Operating Voltage Range:** 4.5V to 5.5V.  
- **Tri-State Outputs:** Allows direct connection to a common bus.  
- **Fully Static Operation:** No refresh cycles required.  
- **CMOS Technology:** Ensures low power dissipation.  
- **TSOP Package:** Compact and suitable for space-constrained applications.  

This information is based solely on manufacturer-provided data for the TC55257DFTL-55L SRAM.
