Description and Introduction

HIGH-SPEED 2K x 8 DUAL-PORT STATIC RAM WITH INTERRUPTS The IDT71321SA35J is a high-speed 16K x 16-bit dual-port static RAM (SRAM) manufactured by Integrated Device Technology (IDT). Below are the key specifications, descriptions, and features:

### **Specifications:**
- **Memory Size:** 16K x 16-bit (262,144 bits)  
- **Organization:** Dual-port SRAM  
- **Access Time:** 35 ns  
- **Operating Voltage:** 5V ±10%  
- **Operating Temperature Range:** Commercial (0°C to +70°C)  
- **Package:** 48-pin J-Lead Plastic Small Outline (SOJ)  
- **I/O Type:** TTL-compatible  

### **Descriptions:**
- The IDT71321SA35J is a dual-port RAM designed for applications requiring simultaneous access from two independent buses.  
- It provides non-contentious access for both ports when accessing different memory locations.  
- Arbitration logic is included to manage simultaneous access to the same memory location.  

### **Features:**
- **True Dual-Port Operation:** Allows independent, simultaneous read/write access from both ports.  
- **Bus Arbitration:** On-chip logic resolves contention when both ports access the same address.  
- **Interrupt Signaling:** Supports hardware interrupt generation for inter-processor communication.  
- **High-Speed Access:** 35 ns access time for fast data transfer.  
- **Low Power Consumption:** Standby power-saving mode reduces power usage when inactive.  
- **TTL-Compatible Inputs/Outputs:** Ensures easy interfacing with standard logic circuits.  
- **Automatic Power-Down:** Chip deselect feature minimizes power consumption.  

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