Description and Introduction

HIGH-SPEED 2K x 8 DUAL-PORT STATIC RAM WITH INTERRUPTS The IDT7132LA55CB is a high-speed 16K x 8 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 (131,072 bits)  
- **Organization:** Dual 8-bit ports  
- **Access Time:** 55 ns  
- **Operating Voltage:** 5V ±10%  
- **Power Consumption:**  
  - Active: 1,000 mW (max)  
  - Standby: 100 mW (max)  
- **Operating Temperature Range:** 0°C to 70°C (commercial grade)  
- **Package:** 48-pin Ceramic DIP (Dual In-line Package)  

### **Descriptions:**
- The IDT7132LA55CB is a dual-port RAM that allows simultaneous access from two independent buses.  
- It is designed for applications requiring high-speed data transfer between processors or systems.  
- Features include automatic power-down for reduced standby current and fully asynchronous operation.  

### **Features:**
- **True Dual-Port Operation:** Independent read/write access on both ports.  
- **Bus Compatibility:** TTL-compatible inputs and outputs.  
- **Interrupt Control:** Built-in interrupt logic for port-to-port communication.  
- **Semaphore (Flag) Logic:** Hardware support for inter-processor coordination.  
- **Expandable:** Allows for width expansion without additional logic.  
- **High Reliability:** Industrial-grade quality with robust design.  

This device is commonly used in multiprocessor systems, communication buffers, and data-sharing applications.

Application Scenarios & Design Considerations

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

Alternative Part Number

  • CY7C132-55PC --: Dual-port SRAM with comparable 2K x 8 organization and 55 ns access time, pin-compatible with the IDT7132 series and widely available as a second source.
  • IS61C1024-55T --: High-speed CMOS SRAM offering similar 55 ns speed grade and 5V operation, suitable functional replacement for the IDT7132LA55CB in many designs.
  • AS7C1024-55TC --: Legacy-compatible 5V asynchronous SRAM with 55 ns access time, often used as a drop-in substitute for older IDT dual-port SRAM parts.
