Description and Introduction

HIGH-SPEED 1K x 8 DUAL-PORT STATIC RAM The IDT7140LA55P is a high-speed, low-power, 16K x 8-bit dual-port static RAM (SRAM) manufactured by Integrated Device Technology (IDT). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Organization:** 16K x 8-bit (131,072 bits)  
- **Supply Voltage:** 5V ±10%  
- **Access Time:** 55 ns  
- **Operating Current:** 120 mA (typical)  
- **Standby Current:** 10 mA (typical)  
- **Package:** 48-pin DIP (Dual In-line Package)  
- **Operating Temperature Range:** 0°C to +70°C (Commercial)  

### **Descriptions:**
- The IDT7140LA55P is a dual-port RAM, allowing simultaneous access from two independent ports (Port A and Port B).  
- It is designed for applications requiring high-speed data transfer between two processors or systems.  
- Features include automatic power-down mode for reduced power consumption when not in use.  
- Supports full asynchronous operation with independent control signals for each port.  

### **Features:**
- **True Dual-Port Operation:** Simultaneous reads/writes from both ports.  
- **Interrupt Flags:** Supports hardware interrupt generation for port-to-port communication.  
- **Busy Logic:** Prevents contention during simultaneous writes to the same address.  
- **CE (Chip Enable) Power-Down:** Reduces power consumption when inactive.  
- **TTL-Compatible Inputs/Outputs:** Ensures compatibility with standard logic levels.  
- **Industrial-Standard Pinout:** Matches industry-standard dual-port RAM configurations.  

This device is commonly used in multiprocessor systems, communication buffers, and other applications requiring shared memory access.
