Description and Introduction

CMOS SyncBiFIFOO 256 x 18 x 2 and 512 x 18 x 2 The IDT72615L25PF 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)  
- **Operating Voltage:** 3.3V (±10%)  
- **Access Time:** 25 ns  
- **Operating Temperature Range:** Commercial (0°C to +70°C)  
- **Package:** 100-pin TQFP (Thin Quad Flat Pack)  
- **Power Consumption:** Low-power CMOS technology  
- **I/O Interface:** 5V-tolerant inputs  

### **Descriptions:**  
- The IDT72615L25PF is a dual-port SRAM designed for high-speed data transfer between two asynchronous buses.  
- It supports simultaneous read/write operations from both ports, making it ideal for shared memory applications.  
- Features include independent control signals for each port, allowing non-contention access.  

### **Features:**  
- **True Dual-Port Operation:** Allows simultaneous access from both ports.  
- **Interrupt Flag:** Supports mailbox communication between ports.  
- **Busy Output:** Prevents contention during simultaneous writes.  
- **Automatic Power-Down:** Reduces power consumption when inactive.  
- **5V-Tolerant Inputs:** Ensures compatibility with mixed-voltage systems.  
- **Industrial-Grade Options:** Available for extended temperature ranges.  

This device is commonly used in networking, telecommunications, and multiprocessor systems requiring high-speed shared memory.
