Description and Introduction

HIGH-SPEED 1K x 8 DUAL-PORT STATIC RAM The **IDT7130SA55J** is a high-speed, low-power **1K x 8 Dual-Port Static RAM (SRAM)** manufactured by **Integrated Device Technology (IDT)**. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Memory Size:** 1K x 8 (8Kbit)  
- **Organization:** Dual-port (independent access to both ports)  
- **Speed:** 55ns access time  
- **Voltage Supply:** 5V ±10%  
- **Operating Temperature Range:** Commercial (0°C to +70°C)  
- **Package:** 48-pin PLCC (Plastic Leaded Chip Carrier)  
- **I/O Type:** TTL-compatible  

### **Descriptions:**
- **Dual-Port Functionality:** Allows simultaneous access from both ports with arbitration logic for contention resolution.  
- **High-Speed Operation:** Optimized for low-latency applications.  
- **Low Power Consumption:** Suitable for power-sensitive designs.  
- **Semaphore Support:** Includes hardware semaphore for inter-processor communication.  
- **Busy/Interrupt Flag:** Provides status indication for shared memory access.  

### **Features:**
- **Independent Read/Write Control** for each port.  
- **Fully Asynchronous Operation** (no clock required).  
- **Automatic Power-Down** when not in use.  
- **On-Chip Arbitration Logic** for resolving simultaneous write conflicts.  
- **Industrial-Grade Reliability** with robust noise immunity.  

This device is commonly used in **multiprocessor systems, communication buffers, and data-sharing applications** where simultaneous access is required.  

(Note: For exact pinout and detailed electrical characteristics, refer to the official **IDT datasheet**.)

Application Scenarios & Design Considerations

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

Alternative Part Number

  • CY7C130-55JC --: Dual-port SRAM with comparable 1Kx8 organization and 55 ns access time, pin-compatible in many PLCC-52 sockets and widely available as a second source.
  • AS7C130-55JC --: Direct functional equivalent dual-port SRAM in the same 1Kx8 density and 55 ns speed grade, often used as a drop-in replacement for legacy IDT dual-port parts.
  • CY7C131-55JC --: Same dual-port SRAM family with matching 55 ns timing and PLCC-52 package, suitable when the 1Kx8 density and interface timing must be preserved.
  • IS61C1024-55J --: High-speed CMOS SRAM in the same PLCC package with comparable 55 ns speed grade, suitable for similar memory applications.
  • AS7C1024-55JC --: Legacy-compatible SRAM replacement with matching 55 ns timing and J-lead package, often used to replace discontinued IDT parts.
