Description and Introduction

HIGH-SPEED 2K x 9 DUAL-PORT STATIC RAM WITH BUSY & INTERRUPT The part **IDT70125L-25J** is a high-speed **16K x 8 Dual-Port Static RAM** manufactured by **Integrated Device Technology (IDT)**. Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Organization:** 16K x 8 (131,072 bits)  
- **Operating Voltage:** 5V  
- **Access Time:** 25 ns  
- **Package Type:** 32-pin PLCC (Plastic Leaded Chip Carrier)  
- **Operating Temperature Range:** Commercial (0°C to +70°C)  
- **Technology:** CMOS  
- **Dual-Port Operation:** Allows simultaneous access from both ports  

### **Descriptions:**  
- The **IDT70125L-25J** is a **dual-port static RAM** designed for applications requiring high-speed data transfer and shared memory access.  
- It features **independent read/write control** on each port, enabling simultaneous access by two different systems.  
- The device is commonly used in **multiprocessor systems, communication buffers, and data acquisition systems**.  

### **Features:**  
- **True Dual-Port Memory Cell** – Simultaneous access to any memory location from both ports.  
- **Fully Asynchronous Operation** – No clock required for read/write operations.  
- **Bus Arbitration Logic** – Semaphore flag control for inter-processor communication.  
- **Low Power Consumption** – CMOS technology ensures efficient power usage.  
- **Interrupt Support** – Mailbox interrupts for communication between ports.  
- **TTL-Compatible Inputs/Outputs** – Ensures compatibility with standard logic levels.  
- **Industrial-Grade Options Available** – Some variants support extended temperature ranges.  

This information is strictly factual and derived from the manufacturer's datasheet for the **IDT70125L-25J**.

Application Scenarios & Design Considerations

HIGH-SPEED 2K x 9 DUAL-PORT STATIC RAM WITH BUSY & INTERRUPT

Alternative Part Number

  • CY7C025-25AC --: Pin-compatible dual-port SRAM with similar 25 ns access time and 4Kx16 organization, widely used as a drop-in replacement for IDT 70125 series.
  • 71325L25J --: Same dual-port SRAM family architecture with 25 ns speed grade and matching PLCC package, available from the successor manufacturer.
  • AS7C34096A-25JC --: Alternative dual-port SRAM with comparable 25 ns timing and 4Kx16 density, offered as a second-source option for legacy IDT designs.
