HIGH-SPEED 2K x 16 CMOS DUAL-PORT STATIC RAMS The IDT7133SA35JI 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 8-bit ports
- **Access Time:** 35 ns
- **Operating Voltage:** 5V ±10%
- **Operating Temperature Range:** -40°C to +85°C (Industrial)
- **Package Type:** 48-Pin PLCC (Plastic Leaded Chip Carrier)
- **Power Consumption:**
- Active: 750 mW (typical)
- Standby: 5 mW (typical)
### **Descriptions:**
- The IDT7133SA35JI is a **dual-port SRAM** that allows simultaneous access from two independent buses.
- It is designed for high-performance applications requiring shared memory access, such as communication systems, multiprocessor systems, and data buffering.
- The device features **non-volatile** operation, meaning data is retained as long as power is supplied.
- It includes **on-chip arbitration logic** to prevent data corruption during simultaneous write operations.
### **Features:**
- **True Dual-Port Operation:** Independent read/write access from both ports.
- **Bus Matching:** 8-bit I/O on both ports.
- **Interrupt Flag:** Supports mailbox communication between processors.
- **Semaphore (Hardware Lock):** Enables software coordination between ports.
- **Automatic Power-Down:** Reduces power consumption when not in use.
- **TTL-Compatible Inputs/Outputs:** Ensures compatibility with standard logic levels.
- **High-Speed Access:** 35 ns access time for fast data transfer.
This device is commonly used in **real-time systems, networking equipment, and embedded applications** where concurrent memory access is required.
