Description and Introduction

HIGH-SPEED 4K x 8 DUAL-PORT STATIC SRAM The **IDT7134-SA70JI** is a high-speed, low-power **4K x 8-bit Dual-Port Static RAM (SRAM)** from Integrated Device Technology (IDT). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Memory Size:** 4K x 8-bit (32 Kb)  
- **Organization:** Dual independent 8-bit ports  
- **Speed:** 70 ns access time  
- **Voltage Supply:** 5V ±10%  
- **Operating Temperature:** Industrial (-40°C to +85°C)  
- **Package:** 48-pin PLCC (Plastic Leaded Chip Carrier)  
- **Technology:** CMOS  

### **Descriptions:**
- The **IDT7134-SA70JI** is a **dual-port RAM**, allowing simultaneous access from two independent buses.  
- It supports **asynchronous operation**, meaning no clock is required for read/write operations.  
- Features **on-chip arbitration logic** to prevent data corruption during simultaneous access to the same memory location.  
- Designed for applications requiring high-speed data transfer and shared memory systems.  

### **Features:**
- **True Dual-Port Operation:** Independent read/write on both ports.  
- **Bus Compatibility:** TTL-compatible inputs and outputs.  
- **Low Power Consumption:** Standby current as low as 10 µA (typical).  
- **Automatic Power-Down:** Reduces power when not in use.  
- **Interrupt Flag:** Supports hardware handshaking between ports.  
- **Semaphore Signaling:** Provides hardware-based communication between processors.  
- **High Reliability:** Industrial-grade temperature range.  

This device is commonly used in **multiprocessor systems, communication buffers, and data acquisition systems**.
