Description and Introduction

HIGH-SPEED 1K x 8 DUAL-PORT STATIC RAM The IDT7130-LA35J is a high-speed 1K x 8-bit dual-port static RAM (SRAM) manufactured by Integrated Device Technology (IDT).  

### **Key Specifications:**  
- **Memory Size:** 1K x 8-bit (8,192 bits)  
- **Organization:** Dual-port (independent read/write ports)  
- **Speed:** 35 ns access time  
- **Voltage Supply:** 5V ±10%  
- **Operating Temperature:** Commercial (0°C to +70°C)  
- **Package:** 48-pin PLCC (Plastic Leaded Chip Carrier)  

### **Descriptions and Features:**  
- **True Dual-Port Memory:** Allows simultaneous access from both ports for reading/writing.  
- **Asynchronous Operation:** No clock required for read/write operations.  
- **Bus Compatibility:** TTL-compatible inputs and outputs.  
- **Automatic Power-Down:** Reduces power consumption when not in use.  
- **Semaphore (Flag) Logic:** Supports inter-processor communication.  
- **Expandable Data Width:** Can be cascaded for wider data buses.  
- **Industrial Standard Pinout:** Compatible with other dual-port RAMs.  

This device is commonly used in multiprocessor systems, communication buffers, and other applications requiring shared memory access.

Application Scenarios & Design Considerations

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

Alternative Part Number

  • CY7C130-35JC --: Pin-compatible dual-port SRAM with similar 1Kx8 organization and 35 ns access time, widely available as a direct functional substitute.
  • IDT7130SA35J --: Same 1Kx8 dual-port SRAM family from the original vendor with 35 ns speed grade, offering guaranteed compatibility though from a different speed/grade series.
  • AS7C31026-35JC --: Second-source dual-port SRAM in the same 1Kx8 configuration and 35 ns timing, suitable as a drop-in replacement when IDT parts are unavailable.
