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 **IDT72V82L15PA** is a high-speed, low-power synchronous FIFO (First-In, First-Out) memory device manufactured by **Integrated Device Technology (IDT)**. Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Density:** 8,192 x 9-bit (8K x 9)  
- **Organization:** 8K words x 9 bits  
- **Operating Voltage:** 3.3V (±10%)  
- **Speed:** 15 ns access time  
- **Operating Frequency:** Up to 66 MHz  
- **I/O Type:** Synchronous, bidirectional  
- **Package:** 64-pin TQFP (Thin Quad Flat Package)  
- **Temperature Range:** Commercial (0°C to +70°C)  

### **Descriptions:**  
- Designed for high-speed data buffering in networking, telecommunications, and computing applications.  
- Supports **synchronous read and write operations** with independent clocks.  
- Features **programmable Almost Full/Almost Empty flags** for flow control.  
- **Low-power CMOS technology** for reduced power consumption.  
- **Retransmit function** allows data to be reread without resetting the FIFO.  

### **Features:**  
- **Bidirectional data bus** for flexible data transfer.  
- **Independent read and write clocks** for asynchronous operation.  
- **Programmable flags** (Almost Full/Almost Empty) to prevent overflow/underflow.  
- **Master Reset (MR) pin** for clearing FIFO contents.  
- **Low standby current** for power efficiency.  
- **JTAG boundary scan** (IEEE 1149.1 compliant) for testability.  

This FIFO is commonly used in applications requiring high-speed data buffering, such as networking equipment, DSP systems, and data acquisition systems.

Alternative Part Number

  • CY7C4255V-15AC --: Pin-compatible synchronous FIFO from Cypress with similar 15 ns speed grade and 5V/3.3V family options, widely used as a drop-in replacement for IDT 72V-series FIFOs.
  • SN74ACT7808-15PAG --: TI synchronous FIFO in the same 15 ns speed class with comparable depth and interface, suitable functional substitute when IDT parts are unavailable.
  • 72V82L15PA --: Renesas acquired IDT's FIFO product line and continues to supply the same 72V82L15PA device under its own brand, ensuring identical specifications and pinout.
