Description and Introduction

HIGH SPEED 4K X 8 DUAL-PORT STATIC RAM WITH SEMAPHORE The IDT71342SA70J is a high-speed 16K x 8-bit dual-port static RAM (SRAM) manufactured by Integrated Device Technology (IDT). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Memory Size:** 16K x 8-bit (131,072 bits)  
- **Organization:** Dual-port (independent access for both ports)  
- **Access Time:** 70 ns  
- **Operating Voltage:** 5V ±10%  
- **Power Consumption:**  
  - Active: 750 mW (typical)  
  - Standby: 55 mW (typical)  
- **Operating Temperature Range:** Commercial (0°C to +70°C)  
- **Package:** 48-pin J-Lead Plastic Chip Carrier (PLCC)  

### **Descriptions:**  
- The IDT71342SA70J is a high-performance, low-power dual-port RAM designed for applications requiring simultaneous access from two independent buses.  
- It features fully independent control, address, and I/O pins for each port, enabling true asynchronous operation.  
- Built-in arbitration logic prevents data corruption during simultaneous writes to the same location.  

### **Features:**  
- **True Dual-Port Operation:** Allows simultaneous reads and writes from both ports.  
- **Bus Compatibility:** TTL-compatible inputs and outputs.  
- **Interrupt Support:** Semaphore flag and mailbox interrupt for inter-processor communication.  
- **Automatic Power-Down:** Reduces power consumption when not in use.  
- **On-Chip Arbitration:** Handles simultaneous access conflicts.  
- **High-Speed Performance:** 70 ns access time for fast data transfer.  

This device is commonly used in multiprocessor systems, communication buffers, and other applications requiring shared memory access.  

(Note: Always verify datasheet details for the latest specifications.)
