Description and Introduction

HIGH-SPEED 2K x 16 CMOS DUAL-PORT STATIC RAMS The IDT7133SA55JI is a high-speed, low-power 16K x 8-bit dual-port static RAM (SRAM) manufactured by Integrated Device Technology (IDT).  

### **Key Specifications:**  
- **Memory Size:** 16K x 8-bit (131,072 bits)  
- **Organization:** Dual-port, fully independent access  
- **Speed:** 55 ns access time  
- **Voltage Supply:** 5V ±10%  
- **Power Consumption:**  
  - Active: 750 mW (typical)  
  - Standby: 5 mW (typical)  
- **Operating Temperature Range:** -40°C to +85°C (Industrial)  
- **Package:** 48-pin J-Lead Plastic Chip Carrier (PLCC)  

### **Features:**  
- **True Dual-Port Operation:** Allows simultaneous reads and writes from both ports.  
- **Semaphore Signaling:** Built-in hardware for inter-processor communication.  
- **Bus Arbitration:** On-chip logic prevents contention during simultaneous access.  
- **TTL-Compatible Inputs/Outputs:** Ensures compatibility with standard logic levels.  
- **Low-Power CMOS Technology:** Reduces power consumption in active and standby modes.  
- **Automatic Power-Down:** Minimizes power when not in use.  

### **Applications:**  
- Multi-processor systems  
- Shared memory configurations  
- Communication buffering  
- Data acquisition systems  

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

Application Scenarios & Design Considerations

HIGH-SPEED 2K x 16 CMOS DUAL-PORT STATIC RAMS

Alternative Part Number

  • CY7C133-55JC --: Dual-port SRAM with comparable 55 ns access time and 2K x 16 organization, pin-compatible with the IDT7133 series and widely available as a drop-in replacement.
  • IS61C1024-55J --: High-speed CMOS SRAM offering similar 55 ns timing and 5V operation; a practical alternative when the dual-port function is not strictly required.
  • AS7C1024-55JC --: 5V asynchronous SRAM with 55 ns access time in a PLCC package, providing a cost-effective substitute for legacy IDT SRAM designs.
