Description and Introduction

HIGH-SPEED 4K x 9DUAL-PORT STATIC RAM The **IDT7014S25J** is a high-speed **16K x 8 Dual-Port Static RAM** manufactured by **Integrated Device Technology (IDT)**. Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Organization:** 16K x 8 (131,072 bits)  
- **Supply Voltage:** 5V ±10%  
- **Access Time:** 25 ns  
- **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: 55 mW (typical)  

### **Descriptions:**  
- **Dual-Port Architecture:** Allows simultaneous access from both ports (left and right) for high-speed data transfer.  
- **Interrupt Control:** Supports mailbox communication with interrupt flags for efficient processor synchronization.  
- **Bus Arbitration:** On-chip semaphore logic prevents contention between ports.  
- **Asynchronous Operation:** Independent control signals for each port (CE, OE, WE).  

### **Features:**  
- **High-Speed Performance:** 25 ns access time for fast data processing.  
- **Fully Static Operation:** No refresh cycles required.  
- **Expandable Data Width:** Can be cascaded for wider data buses.  
- **Low-Power Standby Mode:** Reduces power consumption when inactive.  
- **Industrial-Grade Reliability:** Robust design for stable operation.  

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

Application Scenarios & Design Considerations

HIGH-SPEED 4K x 9DUAL-PORT STATIC RAM

Alternative Part Number

  • CY7C144-25JXC --: Pin-compatible 4K x 18 dual-port SRAM with 25 ns access time, direct functional replacement for the IDT7014S25J in PLCC packaging.
  • IS61C1024-25J --: High-speed 25 ns SRAM in PLCC package from a well-established memory vendor, suitable as a drop-in substitute for the same socket and timing class.
  • AS7C4096A-25JC --: Legacy-compatible 25 ns SRAM in PLCC, offered by a vendor specializing in end-of-life memory replacements for IDT parts.
  • 71342SA25J --: Same 4K x 18 dual-port SRAM architecture and 25 ns speed grade, offered under the Renesas/IDT 71342 series naming.
  • AS7C34096A-25JCN --: Drop-in 4K x 18 dual-port SRAM replacement with matching 25 ns timing, commonly used as a second-source alternative.
