Description and Introduction

HIGH-SPEED 1K x 8 DUAL-PORT STATIC RAM The IDT7130-SA55J is a high-speed 1K x 8 Dual-Port Static RAM (SRAM) manufactured by Integrated Device Technology (IDT).  

### **Specifications:**  
- **Memory Size:** 1K x 8 (8K bits)  
- **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 Ceramic DIP (Dual In-line Package)  

### **Features:**  
- **True Dual-Port Operation:** Allows simultaneous reads and writes from both ports.  
- **Bus Compatibility:** TTL-compatible inputs and outputs.  
- **Automatic Power-Down:** Reduces power consumption when not in use.  
- **Interrupt Flag:** Supports mailbox communication between ports.  
- **On-Chip Arbitration:** Prevents contention during simultaneous access to the same memory location.  
- **High-Speed Performance:** 55ns access time for fast data transfer.  

### **Applications:**  
- Used in multiprocessor systems, communication buffers, and data sharing applications.

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 55ns access time, widely available as a direct functional substitute.
  • AS7C130-55JC --: Alliance Memory second-sources the IDT7130 dual-port SRAM family with matching pinout, speed grade, and package.
  • IDT7005S55J --: Same manufacturer dual-port SRAM family with comparable 55ns speed and J-lead package, usable where slight density differences are acceptable.
