Description and Introduction

HIGH-SPEED 1K x 8 DUAL-PORT STATIC RAM The **IDT7130LA55J** is a high-speed **1K x 8 Dual-Port Static RAM** manufactured by **Integrated Device Technology (IDT)**. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Memory Size:** 1K x 8 (8K bits)  
- **Organization:** Dual-port (simultaneous access)  
- **Supply Voltage:** 5V ±10%  
- **Access Time:** 55ns  
- **Operating Current:** 150mA (typical)  
- **Standby Current:** 10mA (typical)  
- **Package:** 48-pin PLCC (Plastic Leaded Chip Carrier)  
- **Operating Temperature Range:** 0°C to +70°C (Commercial)  

### **Descriptions:**
- The **IDT7130LA55J** is a **dual-port static RAM** that allows independent, simultaneous access from two separate buses.  
- It is designed for applications requiring high-speed data sharing between processors or systems.  
- Features **on-chip arbitration logic** to prevent data corruption during simultaneous writes.  
- Suitable for **FIFO buffers, shared memory systems, and multiprocessor applications**.  

### **Features:**
- **True Dual-Port Memory:** Independent read/write operations on both ports.  
- **Fully Asynchronous Operation:** No clock required.  
- **Bus Compatibility:** TTL-compatible inputs and outputs.  
- **Semaphore (Flag) Logic:** For inter-processor communication.  
- **Automatic Power-Down:** Reduces power consumption when not in use.  
- **High-Speed Access:** 55ns maximum access time.  
- **Industrial-Grade Options Available:** Extended temperature range versions (e.g., IDT7130SA55J).  

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

Application Scenarios & Design Considerations

HIGH-SPEED 1K x 8 DUAL-PORT STATIC RAM

Alternative Part Number

  • CY7C130-55JC --: Pin-compatible dual-port SRAM with similar 1Kx8 organization and 55 ns access time, widely used as a drop-in replacement for IDT7130 series.
  • AS7C130-55JC --: Direct functional equivalent dual-port SRAM from Alliance Memory, same 1Kx8 density and 55 ns speed grade, often stocked as an IDT7130 alternative.
  • IS61C1024-55J --: Comparable high-speed SRAM in a PLCC package with 55 ns access time; verify pinout and dual-port functionality before substitution.
  • CY7C131-55JC --: Another Cypress dual-port SRAM in the same family with comparable organization and timing, suitable when the 130 series is unavailable.
