HIGH-SPEED 2K x 8 DUAL-PORT STATIC RAM WITH INTERRUPTS The IDT7132SA55CB is a high-speed 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, 8-bit word width
- **Access Time:** 55 ns
- **Operating Voltage:** 5V ±10%
- **Operating Temperature Range:** 0°C to +70°C (Commercial)
- **Package Type:** 48-pin Ceramic DIP (Dual In-line Package)
- **Power Consumption:**
- Active: 750 mW (typical)
- Standby: 55 mW (typical)
### **Descriptions:**
- The IDT7132SA55CB is a **dual-port RAM**, allowing simultaneous access from two independent buses.
- It is designed for high-speed applications requiring shared memory access, such as multiprocessor systems, communication buffers, and data acquisition systems.
- Features **on-chip arbitration logic** to prevent data corruption during simultaneous write operations to the same address.
### **Features:**
- **True Dual-Port Operation:** Independent read/write access from both ports.
- **Fully Asynchronous Operation:** No clock required.
- **Bus Compatibility:** TTL-compatible inputs and outputs.
- **Automatic Power-Down:** Reduces power consumption when not in use.
- **Interrupt Flag:** Supports mailbox communication between ports.
- **Semaphore (Flag) Logic:** Enables hardware handshaking between processors.
- **Industrial-Grade Options Available** (e.g., IDT7132LA for extended temperature ranges).
This device is suitable for applications requiring fast, conflict-free memory sharing between multiple processors or systems.
