Description and Introduction

HIGH-SPEED 32K x 16 DUAL-PORT STATIC RAM The IDT7027L25PF is a high-speed, low-power, 16K x 16 dual-port static RAM (SRAM) manufactured by Integrated Device Technology (IDT). Below are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Memory Size:** 16K x 16 (262,144 bits)  
- **Organization:** Dual-port, 16-bit wide  
- **Speed:** 25 ns access time  
- **Voltage Supply:** 5V ±10%  
- **Operating Temperature:** Commercial (0°C to +70°C) or Industrial (-40°C to +85°C)  
- **Package:** 64-pin Plastic Thin Quad Flat Pack (TQFP)  
- **Power Consumption:** Low power standby mode available  

### **Descriptions:**  
- The IDT7027L25PF is a dual-port RAM allowing simultaneous access from two independent buses.  
- It supports asynchronous operation with semaphore control for inter-processor communication.  
- Designed for high-performance applications requiring shared memory access.  

### **Features:**  
- **True Dual-Port Operation:** Independent read/write access from both ports.  
- **Semaphore Control:** Hardware handshake for shared resource management.  
- **Interrupt Support:** Busy flag and interrupt generation for port contention resolution.  
- **Low Power:** Standby power-saving mode reduces consumption when inactive.  
- **High-Speed Performance:** 25 ns access time for fast data transfer.  
- **TTL-Compatible I/O:** Ensures compatibility with standard logic levels.  
- **Industrial-Grade Options:** Available for extended temperature ranges.  

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

Application Scenarios & Design Considerations

HIGH-SPEED 32K x 16 DUAL-PORT STATIC RAM

Alternative Part Number

  • CY7C027V-25AXC --: Dual-port SRAM with similar 32Kx16 organization and 25 ns access time, pin-compatible footprint in a TQFP package, widely available as a direct functional substitute.
  • 71342SA25PF --: Same dual-port SRAM family architecture with 25 ns speed grade and matching PF package, offering equivalent read/write arbitration behavior.
  • AS7C34098A-25TC --: SRAM with comparable density and 25 ns access time in a similar package, suitable as a lower-cost drop-in alternative for legacy designs.
