Description and Introduction

HIGH-SPEED 8K x 16 SEQUENTIAL ACCESS RANDOM ACCESS MEMORY (SARAM?) The **IDT70825L20PF** is a high-speed, low-power, 8K x 8 dual-port static RAM (SRAM) manufactured by Integrated Device Technology (IDT). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Memory Size:** 8K x 8 (65,536 bits)  
- **Organization:** Dual-port (independent access for both ports)  
- **Supply Voltage:** 5V ±10%  
- **Access Time:** 20 ns  
- **Operating Current:** 120 mA (typical)  
- **Standby Current:** 10 mA (typical)  
- **Package:** 68-pin PLCC (Plastic Leaded Chip Carrier)  
- **Operating Temperature Range:** Commercial (0°C to +70°C)  

### **Descriptions:**
- The **IDT70825L20PF** is a **dual-port SRAM** that allows simultaneous access from two separate buses, making it ideal for multiprocessor and real-time systems.  
- It includes **on-chip arbitration logic** to prevent data corruption during simultaneous write operations to the same address.  
- The device supports **asynchronous operation**, enabling independent read/write cycles on each port.  

### **Features:**
- **True Dual-Port Operation:** Independent read/write access for both ports.  
- **High-Speed Performance:** 20 ns access time.  
- **Low Power Consumption:** CMOS technology for reduced power usage.  
- **Bus Compatibility:** TTL-compatible inputs and outputs.  
- **Automatic Power-Down:** Reduces power when not in use.  
- **Interrupt Support:** Mailbox feature for inter-processor communication.  
- **Semaphore Control:** Hardware-based semaphore for shared resource management.  

This device is commonly used in **multiprocessor systems, communication buffers, and data acquisition systems** where simultaneous memory access is required.
