Description and Introduction

HIGH-SPEED 2K x 8 DUAL-PORT STATIC RAM WITH INTERRUPTS The IDT7132LA55J is a high-speed 16K x 8 dual-port static RAM (SRAM) manufactured by Integrated Device Technology (IDT).  

### **Key Specifications:**  
- **Organization:** 16K x 8 (131,072 bits)  
- **Access Time:** 55 ns  
- **Operating Voltage:** 5V ±10%  
- **Power Consumption:**  
  - Active: 1,100 mW (max)  
  - Standby: 55 mW (max)  
- **Package:** 48-pin PLCC (Plastic Leaded Chip Carrier)  
- **Operating Temperature Range:** 0°C to +70°C  

### **Features:**  
- **True Dual-Port Operation:** Allows simultaneous access from both ports.  
- **Semaphore (Flag) Control:** Hardware-based handshake for inter-processor communication.  
- **Bus Arbitration:** On-chip logic resolves simultaneous access conflicts.  
- **Fully Static Operation:** No clock or refresh required.  
- **TTL-Compatible Inputs/Outputs:** Ensures compatibility with standard logic levels.  
- **Industrial Standard Pinout:** Matches industry-standard dual-port RAMs.  

### **Applications:**

This device is designed for high-performance systems requiring fast, reliable dual-port memory access.

Application Scenarios & Design Considerations

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

Alternative Part Number

  • CY7C132-55JC --: Dual-port SRAM with comparable 2Kx8 organization and 55 ns access time, pin-compatible in many PLCC sockets and widely available as a second source.
  • IS61C1024-55J --: High-speed SRAM in a PLCC package with 55 ns speed grade; ISSI parts are commonly used as drop-in replacements for legacy IDT SRAMs.
  • AS7C1024-55JC --: Alliance Memory specializes in legacy SRAM replacements, offering 55 ns PLCC devices that match the timing and package of the original IDT part.
