Description and Introduction

HIGH-SPEED 4K x 8 DUAL-PORT STATIC SRAM The IDT7134LA35J is a high-speed 4K x 8-bit dual-port static RAM (SRAM) manufactured by Integrated Device Technology (IDT). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Memory Size:** 4K x 8-bit (32Kb)  
- **Organization:** Dual-port (independent read/write ports)  
- **Speed:** 35 ns 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  
- **Power Consumption:** Active: 750 mW (typical), Standby: 5 mW (typical)  

### **Descriptions:**
- The IDT7134LA35J is a dual-port RAM that allows simultaneous access from two independent buses.  
- It is designed for high-speed data transfer applications where contention-free operation is required.  
- Features include automatic power-down for reduced standby power consumption.  

### **Features:**
1. **True Dual-Port Operation:** Independent read/write access from both ports.  
2. **High-Speed Performance:** 35 ns access time.  
3. **Low Power Consumption:** CMOS technology for reduced power usage.  
4. **Bus Arbitration Logic:** Built-in semaphore flag for inter-port communication.  
5. **TTL Compatibility:** Fully compatible with TTL levels.  
6. **Automatic Power-Down:** Reduces power when not in use.  
7. **Industrial Standard Pinout:** Compatible with other 4K x 8 dual-port RAMs.  

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

(Note: For detailed electrical characteristics and timing diagrams, refer to the official IDT datasheet.)

Application Scenarios & Design Considerations

HIGH-SPEED 4K x 8 DUAL-PORT STATIC SRAM

Alternative Part Number

  • CY7C134LA-35JC --: Cypress second-source equivalent dual-port SRAM in the same 35 ns speed grade and PLCC package, widely used as a drop-in replacement for IDT7134 family parts.
  • AS7C134-35JC --: Alliance Memory produces pin-compatible dual-port SRAM replacements for legacy IDT parts, offering the same 35 ns access time and 5V operation.
  • 7134LA35J --: Renesas acquired IDT's memory portfolio and continues to supply the same dual-port SRAM device under its own branding, ensuring identical specifications and form factor.
