HIGH-SPEED 1K x 8 DUAL-PORT STATIC RAM The **IDT7140LA100J** is a high-speed, low-power, dual-port static RAM (SRAM) manufactured by **Integrated Device Technology (IDT)**. Below are its specifications, descriptions, and features based on factual data:
### **Specifications:**
- **Part Number:** IDT7140LA100J
- **Manufacturer:** IDT (Integrated Device Technology)
- **Type:** Dual-Port SRAM
- **Density:** 16K (2K x 8-bit)
- **Speed:** 100 ns access time
- **Voltage Supply:** 5V ±10%
- **Operating Temperature:** Commercial (0°C to +70°C)
- **Package:** 48-pin PLCC (Plastic Leaded Chip Carrier)
- **I/O Type:** TTL-compatible
### **Descriptions:**
- The **IDT7140LA100J** is a **16K (2K x 8-bit)** dual-port RAM designed for high-speed data transfer between two asynchronous buses.
- It allows simultaneous access from both ports, making it ideal for **interprocessor communication, buffering, and shared memory applications**.
- The device features **independent control signals** for each port, enabling non-contention read/write operations.
- It is **fully static**, meaning no clock or refresh is required.
### **Features:**
1. **True Dual-Port Operation** – Independent read/write access from both ports.
2. **High-Speed Access** – **100 ns** maximum access time.
3. **Low Power Consumption** – CMOS technology for reduced power usage.
4. **TTL-Compatible Inputs/Outputs** – Ensures compatibility with standard logic levels.
5. **Bus Arbitration Support** – Includes **SEM (Semaphore)** flag control for port synchronization.
6. **Expandable Data Width** – Can be cascaded for wider word configurations.
7. **Industrial Standard Pinout** – Compatible with other industry-standard dual-port RAMs.
8. **Automatic Power-Down** – Reduces power when not in use.
