### **Specifications:**  
- **Organization:** 32K words × 8 bits  
- **Access Time:** 85 ns  
- **Operating Voltage:** 5V ± 10%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 600-mil 28-pin DIP (Dual In-line Package)  
- **Standby Current (Typical):** 10 µA (CMOS level)  
- **Operating Current (Typical):** 40 mA (at maximum frequency)  
- **Data Retention Voltage:** 2V (min)  

### **Descriptions:**  
- The TC55257DPI-85L is a low-power CMOS SRAM designed for high-speed applications.  
- It features a fully static operation, meaning no clock or refresh is required.  
- It is compatible with TTL levels for easy interfacing with microprocessors.
