Description and Introduction

HIGH SPEED 4K X 8 DUAL-PORT STATIC RAM WITH SEMAPHORE The **IDT71342LA45JI** is a high-speed, low-power dual-port static RAM (SRAM) manufactured by **Integrated Device Technology (IDT)**. Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Memory Type:** Dual-Port SRAM  
- **Density:** 16K x 8 (131,072 bits)  
- **Organization:** 16,384 words × 8 bits  
- **Access Time:** 45 ns  
- **Operating Voltage:** 5V ±10%  
- **Operating Temperature Range:** -40°C to +85°C (Industrial)  
- **Package:** 48-lead PLCC (Plastic Leaded Chip Carrier)  
- **I/O Interface:** 5V TTL-compatible  

### **Descriptions:**  
- The **IDT71342LA45JI** is a **dual-port RAM** that allows simultaneous access from two independent buses.  
- It is designed for high-speed data transfer applications where concurrent read/write operations are required.  
- Features **on-chip arbitration logic** to prevent data corruption during simultaneous access to the same memory location.  
- Suitable for **inter-processor communication, buffering, and data sharing** in multiprocessor systems.  

### **Features:**  
- **True Dual-Port Operation:** Independent read/write access from both ports.  
- **Bus Matching:** Directly interfaces with 8-bit microprocessors.  
- **Low Power Consumption:** Standby mode reduces power usage.  
- **Automatic Power-Down:** Enabled when chip is deselected.  
- **Interrupt Flags:** Supports mailbox communication between ports.  
- **High Noise Immunity:** CMOS technology ensures robustness.  

This device is commonly used in **telecommunications, networking, and embedded systems** where fast, concurrent memory access is critical.  

(Note: Always refer to the official **IDT datasheet** for complete technical details.)
