Description and Introduction

HIGH-SPEED 2K x 8 DUAL-PORT STATIC RAM WITH INTERRUPTS The IDT7132SA25J is a high-speed 16K 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:** 16K x 8-bit (128 Kb)  
- **Organization:** Dual-port (independent access for both ports)  
- **Speed:** 25 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  

### **Descriptions:**
- The IDT7132SA25J is a dual-port RAM that allows simultaneous access from two independent buses, making it ideal for shared-memory applications.  
- It features non-multiplexed address and data buses for both ports, enabling high-speed data transfers.  
- Designed for applications requiring real-time data sharing, such as communication systems, multiprocessing, and data buffering.  

### **Features:**
- **True Dual-Port Operation:** Independent read/write access from both ports.  
- **Bus Arbitration:** On-chip semaphore (flag) logic for inter-port communication.  
- **High-Speed Performance:** 25 ns access time for fast data processing.  
- **Low Power Consumption:** Standby mode reduces power usage when inactive.  
- **Automatic Power-Down:** Chip deselect feature minimizes power consumption.  
- **Interrupt Support:** Mailbox feature for inter-processor communication.  
- **Expandable:** Can be cascaded for larger memory configurations.  

This device is commonly used in high-performance embedded systems, networking, and telecommunications applications.  

(Note: Always verify datasheets for the latest specifications.)

Application Scenarios & Design Considerations

HIGH-SPEED 2K x 8 DUAL-PORT STATIC RAM WITH INTERRUPTS

Alternative Part Number

  • CY7C132-25JC --: Dual-port SRAM with comparable 2K x 16 organization and 25 ns access time, pin-compatible in many PLCC-52 sockets and widely available as a second-source option.
  • AS7C132-25JC --: Direct functional equivalent dual-port SRAM with 25 ns speed grade in the same PLCC package, often used as a drop-in replacement for IDT7132 devices.
  • IS61C132-25J --: Dual-port SRAM offering similar density, organization and 25 ns timing, suitable as an alternative when IDT parts are unavailable.
