HIGH-SPEED 1K x 8 DUAL-PORT STATIC RAM The IDT7130LA20P is a high-speed 1K x 8 dual-port static RAM manufactured by Integrated Device Technology (IDT). Below are its specifications, descriptions, and features:
### **Specifications:**
- **Memory Size:** 1K x 8 (8,192 bits)
- **Organization:** Dual 8-bit ports
- **Access Time:** 20 ns
- **Operating Voltage:** 5V ±10%
- **Power Consumption:**
- Active: 750 mW (typical)
- Standby: 55 mW (typical)
- **Operating Temperature Range:** 0°C to 70°C (commercial)
- **Package Type:** 48-pin DIP (Dual In-line Package)
- **Technology:** CMOS
### **Descriptions:**
- The IDT7130LA20P is a high-performance, low-power dual-port RAM designed for applications requiring simultaneous access from two independent buses.
- It supports fully asynchronous operation, allowing independent read/write operations on both ports.
- The device includes built-in arbitration logic to prevent data corruption during simultaneous write operations to the same memory location.
### **Features:**
- **True Dual-Port Operation:** Simultaneous access from both ports.
- **Asynchronous Operation:** No clock required for read/write operations.
- **Bus Compatibility:** TTL-compatible inputs and outputs.
- **On-Chip Arbitration:** Prevents contention during simultaneous writes.
- **Low Power Consumption:** Standby mode reduces power usage.
- **Interrupt Flag:** Supports hardware interrupt generation for port-to-port communication.
- **Expandable Data Width:** Can be cascaded for wider data buses.
This device is commonly used in communication systems, multiprocessor systems, and data buffering applications.
