Description and Introduction

HIGH-SPEED 2K x 16 CMOS DUAL-PORT STATIC RAMS The **IDT7133LA90J** is a high-speed, low-power **dual-port static RAM (SRAM)** manufactured by **Integrated Device Technology (IDT)**. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Memory Size:** 4K × 8-bit (32 Kbit)  
- **Organization:** Dual 4K × 8-bit independent ports  
- **Access Time:** 90 ns  
- **Operating Voltage:** 5V ± 10%  
- **Power Consumption:**  
  - **Active:** 750 mW (typical)  
  - **Standby:** 55 mW (typical)  
- **Operating Temperature Range:**  
  - **Commercial:** 0°C to +70°C  
  - **Industrial:** -40°C to +85°C  
- **Package Type:** 48-pin PLCC (Plastic Leaded Chip Carrier)  

### **Descriptions:**
- **Dual-Port Architecture:** Allows simultaneous access from both ports for high-speed data transfer.  
- **Asynchronous Operation:** No clock required for read/write operations.  
- **Semaphore Support:** Includes hardware semaphore for inter-port communication.  
- **Bus Matching:** Compatible with 8-bit microprocessors.  
- **High-Speed Performance:** Optimized for applications requiring fast data access.  

### **Features:**
- **Independent Read/Write Control:** Each port operates independently.  
- **On-Chip Arbitration:** Prevents data corruption during simultaneous writes.  
- **Low-Power Standby Mode:** Reduces power consumption when inactive.  
- **TTL-Compatible I/O:** Ensures compatibility with standard logic levels.  
- **Industrial-Grade Reliability:** Suitable for harsh environments.  

This device is commonly used in **communication systems, networking equipment, and embedded systems** where fast, concurrent data access is required.
