Description and Introduction

DUAL CMOS SyncFIFO The IDT72811L15PFI 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:**
- **Part Number:** IDT72811L15PFI  
- **Type:** Synchronous FIFO  
- **Organization:** 512 x 18 bits  
- **Speed:** 15 ns access time  
- **Operating Voltage:** 3.3V  
- **Operating Temperature Range:** Industrial (-40°C to +85°C)  
- **Package:** 64-pin TQFP (Thin Quad Flat Pack)  
- **Clock Frequency:** Up to 66 MHz  
- **I/O Type:** 3.3V CMOS  

### **Descriptions:**
- The IDT72811L15PFI is a synchronous FIFO designed for high-speed data buffering applications.  
- It supports simultaneous read and write operations with independent clocks.  
- Features programmable almost-full and almost-empty flags for flow control.  
- Suitable for networking, telecommunications, and data processing systems.  

### **Features:**
- **High-Speed Operation:** 15 ns access time, 66 MHz clock frequency.  
- **Low Power Consumption:** Optimized for 3.3V operation.  
- **Synchronous Operation:** Independent read and write clocks.  
- **Programmable Flags:** Almost-full (AF) and almost-empty (AE) indicators.  
- **Retransmit Function:** Allows data to be reread from the start.  
- **Master Reset:** Clears FIFO pointers and flags.  
- **Industrial Temperature Support:** Operates reliably in harsh environments.  

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

(Note: Always refer to the official datasheet for detailed technical specifications and application guidelines.)

Application Scenarios & Design Considerations

DUAL CMOS SyncFIFO

Alternative Part Number

  • CY7C4281V-15AXI --: Pin-compatible synchronous FIFO from Cypress with similar 15 ns speed grade and 5V/3.3V operation, widely used as a drop-in replacement for IDT 72811 series.
  • SN74ACT7808-15PAG --: TI synchronous FIFO with comparable depth and 15 ns access time, functionally equivalent architecture suitable for buffering applications.
  • 72V211L15PF --: Renesas (formerly IDT) FIFO in the same 72V family with matching 15 ns speed and pinout, offering a direct functional substitute.
  • CY7C4255V-15AXC --: Pin-compatible synchronous FIFO with similar 15 ns speed grade and 5V/3.3V operation, widely available as a drop-in functional replacement.
  • SN74ACT7808-15FN --: Synchronous FIFO in the same density class with 15 ns access time, suitable for buffering applications requiring the original's timing.
