Description and Introduction

HIGH-SPEED 8K x 8 DUAL-PORT STATIC RAM The IDT7005S55J is a high-speed 16K x 8 dual-port static RAM (SRAM) manufactured by Integrated Device Technology (IDT). Below are the specifications, descriptions, and features:

### **Specifications:**
- **Part Number:** IDT7005S55J  
- **Manufacturer:** IDT (Integrated Device Technology)  
- **Type:** Dual-Port Static RAM (SRAM)  
- **Density:** 16K x 8 (131,072 bits)  
- **Speed:** 55ns access time  
- **Operating Voltage:** 5V ±10%  
- **Package:** 48-pin PLCC (Plastic Leaded Chip Carrier)  
- **Operating Temperature Range:** Commercial (0°C to +70°C)  
- **I/O Type:** TTL-compatible  

### **Descriptions:**
- The IDT7005S55J is a high-performance dual-port RAM designed for applications requiring simultaneous access from two independent buses.  
- It features separate control, address, and data pins for each port, allowing independent read/write operations.  
- The device is commonly used in multiprocessor systems, communication buffers, and data-sharing applications.  

### **Features:**
- **True Dual-Port Operation:** Simultaneous access from both ports.  
- **High-Speed Access:** 55ns maximum access time.  
- **Fully Asynchronous Operation:** No clock required.  
- **Bus Compatibility:** TTL-compatible inputs and outputs.  
- **On-Chip Arbitration:** Prevents contention when both ports access the same memory location.  
- **Low Power Consumption:** Standby mode reduces power usage.  
- **Industrial Standard Pinout:** Compatible with other industry-standard dual-port RAMs.  

This information is based on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

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

Alternative Part Number

  • CY7C006A-55JC --: Dual-port SRAM with comparable 8Kx16 organization and 55 ns access time, pin-compatible in many designs and widely available as a second source.
  • 7130LA55J --: IDT/Renesas dual-port SRAM in the same 8Kx16 class with 55 ns speed grade, offering a direct functional replacement from the same vendor family.
  • AS7C34096A-55JCN --: Alliance Memory SRAM with matching 55 ns timing and JEDEC PLCC package, commonly used as a drop-in alternative when the original IDT part is unavailable.
