Description and Introduction

HIGH-SPEED 2K x 8 DUAL-PORT STATIC RAM WITH INTERRUPTS The IDT71321SA45J is a high-speed 16K x 16-bit dual-port static RAM (SRAM) manufactured by Integrated Device Technology (IDT). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Organization:** 16K x 16-bit  
- **Technology:** CMOS  
- **Speed:** 45 ns access time  
- **Voltage Supply:** 5V ±10%  
- **Operating Temperature Range:** Commercial (0°C to +70°C)  
- **Package:** 48-pin J-Lead Plastic Chip Carrier (PLCC)  

### **Descriptions:**
- **Dual-Port RAM:** Allows simultaneous access from two independent buses for high-speed data transfer.  
- **Asynchronous Operation:** No clock required for read/write operations.  
- **Interrupt Support:** Features BUSY and INT flags for port arbitration and communication.  
- **Low Power Consumption:** Standby mode reduces power usage when inactive.  

### **Features:**
- **Independent Read/Write Ports:** Enables simultaneous access without contention.  
- **BUSY Output:** Prevents data corruption during simultaneous write operations.  
- **Semaphore Signaling:** Supports hardware-based communication between ports.  
- **TTL-Compatible Inputs/Outputs:** Ensures compatibility with standard logic levels.  
- **Industrial-Grade Options Available:** Extended temperature range variants (e.g., IDT71321LA45J).  

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

For detailed electrical characteristics and timing diagrams, refer to the official IDT datasheet.
