Description and Introduction

BUS-MATCHING BIDIRECTIONAL FIFO 512 x 18-BIT . 1024 x 9-BIT 1024 x 18-BIT . 2048 x 9-BIT The IDT72520L35J is a high-speed, low-power 16K x 8 dual-port static RAM (SRAM) manufactured by Integrated Device Technology (IDT).  

### **Key Specifications:**  
- **Memory Size:** 16K x 8 (131,072 bits)  
- **Organization:** Dual-port, allowing simultaneous access from both ports  
- **Speed:** 35 ns access time  
- **Voltage Supply:** 5V ±10%  
- **Operating Temperature Range:** Commercial (0°C to +70°C)  
- **Package:** 48-pin PLCC (Plastic Leaded Chip Carrier)  

### **Features:**  
- **True Dual-Port Operation:** Independent read/write access on both ports  
- **Bus Compatibility:** TTL-compatible inputs and outputs  
- **Low Power Consumption:** Standby mode reduces power usage  
- **Interrupt Flag:** Supports hardware interrupt signaling for port contention  
- **Semaphore Control:** Built-in semaphore logic for inter-processor communication  
- **Automatic Power-Down:** Reduces power when not in use
