Description and Introduction

HIGH-SPEED 2K x 16 CMOS DUAL-PORT STATIC RAMS The **IDT7143-LA35J** is a high-speed, low-power **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-port (independent read/write ports)
- **Supply Voltage:** 5V ±10%
- **Access Time:** 35 ns (max)
- **Operating Current:** 150 mA (typical)
- **Standby Current:** 10 mA (typical)
- **Package:** 48-pin PLCC (Plastic Leaded Chip Carrier)
- **Operating Temperature Range:** 0°C to +70°C (commercial grade)
- **Technology:** CMOS

### **Descriptions:**
- The **IDT7143-LA35J** is a **dual-port SRAM** that allows simultaneous access from two independent buses.
- It is designed for applications requiring high-speed data sharing between processors or systems.
- Features **on-chip arbitration logic** to prevent contention when both ports access the same memory location.
- Supports **asynchronous operation**, allowing each port to function independently.

### **Features:**
- **True Dual-Port Operation:** Independent read/write on both ports.
- **Bus Compatibility:** TTL-compatible inputs and outputs.
- **Automatic Power-Down:** Reduces power consumption when not in use.
- **Interrupt Flag:** Supports mailbox communication between processors.
- **Semaphore (Hardware Lock) Mechanism:** Ensures controlled access to shared resources.
- **High-Speed Performance:** 35 ns access time for fast data transfer.
- **Industrial-Standard Pinout:** Compatible with other dual-port SRAMs.

This device is commonly used in **multiprocessor systems, communication buffers, and data acquisition systems** where simultaneous access to shared memory is required.
