HIGH-SPEED 3.3V 32K x 16 DUAL-PORT STATIC RAM The IDT70V27L15PF is a high-speed, low-power 16K x 16 dual-port static RAM (SRAM) manufactured by Integrated Device Technology (IDT). Below are its key specifications, descriptions, and features:
### **Specifications:**
- **Organization:** 16K x 16 (262,144 bits)
- **Supply Voltage:** 3.3V ±10%
- **Access Time:** 15 ns
- **Operating Current:** 85 mA (typical)
- **Standby Current:** 5 mA (typical)
- **Package:** 100-pin TQFP (Thin Quad Flat Pack)
- **Operating Temperature Range:** Commercial (0°C to +70°C) or Industrial (-40°C to +85°C)
- **I/O Compatibility:** 3.3V LVTTL
### **Descriptions:**
- The IDT70V27L15PF is a dual-port SRAM designed for applications requiring simultaneous access from multiple processors or controllers.
- It features independent access ports, allowing read/write operations from both ports without contention.
- The device includes semaphore (flag) control for inter-processor communication and hardware arbitration to prevent data corruption during simultaneous writes.
### **Features:**
- **True Dual-Port Operation:** Independent read/write access on both ports.
- **High-Speed Performance:** 15 ns access time.
- **Low Power Consumption:** Optimized for 3.3V operation.
- **Bus Matching:** On-chip address latching and byte control.
- **Semaphore Control:** Built-in hardware for inter-processor coordination.
- **Automatic Power-Down:** Reduces power when not in use.
- **Industrial Temperature Support:** Available in extended temperature range (-40°C to +85°C).
This device is commonly used in networking, telecommunications, and multi-processor systems where high-speed, low-power, and concurrent data access are required.
