Description and Introduction

3.3 Volt CMOS DUAL ASYNCHRONOUS FIFO DUAL 512 x 9, DUAL 1,024 x 9 DUAL 2,048 x 9, DUAL 4,096 X 9 The **IDT72V82L20PA** is a high-speed, low-power **First-In, First-Out (FIFO)** memory device manufactured by **Integrated Device Technology (IDT)**. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Memory Size:** 16K x 18 bits (288 Kbits)  
- **Operating Voltage:** 3.3V  
- **Speed:** 20 ns access time  
- **Organization:** Synchronous FIFO  
- **Package:** 64-pin TQFP (Thin Quad Flat Pack)  
- **Operating Temperature Range:** Commercial (0°C to +70°C)  

### **Descriptions:**
- Designed for high-speed data buffering applications.  
- Supports **synchronous** read and write operations with independent clocks.  
- Features **programmable flag** signals (Almost Full, Almost Empty, Full, Empty).  
- Low-power CMOS technology for efficient operation.  

### **Features:**
- **High-Speed Operation:** 20 ns access time for fast data transfer.  
- **Dual-Clock Architecture:** Independent read and write clocks for asynchronous operation.  
- **Flag Control:** Configurable flag logic for efficient data management.  
- **Retransmit Function:** Allows data to be re-read from the beginning of the FIFO.  
- **Low Power Consumption:** Optimized for power-sensitive applications.  
- **Wide Voltage Compatibility:** 3.3V operation with 5V-tolerant inputs.  

This FIFO is commonly used in networking, telecommunications, and data processing systems where high-speed buffering is required.

Application Scenarios & Design Considerations

3.3 Volt CMOS DUAL ASYNCHRONOUS FIFO DUAL 512 x 9, DUAL 1,024 x 9 DUAL 2,048 x 9, DUAL 4,096 X 9

Alternative Part Number

  • CY7C4255V-25AXC --: Cypress synchronous FIFO in the same 2K x 18 density class with similar 20-25 ns access time, pin-compatible PLCC/TQFP options, and widely available as an IDT FIFO replacement.
  • SN74ACT7808-20PN --: TI 2K x 18 asynchronous/synchronous FIFO with comparable 20 ns speed grade and PLCC package, suitable as a functional substitute for the IDT72V82L20PA in buffering applications.
  • 72V82L20PA --: Renesas acquired IDT's FIFO product line and continues to supply the same 72V82L20PA device under the Renesas brand, ensuring identical function, speed, and package.
