Description and Introduction

CMOS SyncFIFOO 256 x 18, 512 x 18, 1024 x 18, 2048 x 18 and 4096 x 18 The IDT72225LB20PF is a high-speed, low-power 16K x 9 synchronous FIFO (First-In, First-Out) memory device manufactured by Integrated Device Technology (IDT). Below are its specifications, descriptions, and features:

### **Specifications:**  
- **Organization:** 16K x 9  
- **Operating Voltage:** 5V  
- **Speed:** 20ns access time  
- **Package:** 32-pin PLCC (Plastic Leaded Chip Carrier)  
- **Operating Temperature Range:** Commercial (0°C to +70°C)  
- **Power Consumption:** Low-power CMOS technology  

### **Descriptions:**  
- The IDT72225LB20PF is a synchronous FIFO designed for high-speed data buffering applications.  
- It supports simultaneous read and write operations with independent clocks.  
- Features programmable flags (Almost Full/Almost Empty) for flow control.  
- Includes retransmit capability for data recovery.  

### **Features:**  
- **High-Speed Operation:** 20ns access time.  
- **Low Power:** CMOS technology for reduced power consumption.  
- **Synchronous Operation:** Independent read and write clocks.  
- **Programmable Flags:** Almost Full (AF) and Almost Empty (AE) for efficient data management.  
- **Retransmit Function:** Allows re-reading of data.  
- **Expandable Depth and Width:** Supports expansion in depth (cascading) and width (byte-wide).  
- **Industrial-Standard Pinout:** Compatible with other FIFO devices.  

This FIFO is commonly used in networking, telecommunications, and data processing applications requiring high-speed buffering.

Application Scenarios & Design Considerations

CMOS SyncFIFOO 256 x 18, 512 x 18, 1024 x 18, 2048 x 18 and 4096 x 18

Alternative Part Number

  • CY7C4255V-20AXC --: Pin-compatible synchronous FIFO with similar 20 ns speed grade and 4K x 18 organization, widely used as a drop-in replacement for IDT72225 series.
  • SN74ACT7805-20PN --: Synchronous FIFO in the same 4K x 18 density class with 20 ns access time, suitable functional alternative when IDT parts are unavailable.
  • 72V225L20PF --: Renesas continues the former IDT FIFO portfolio; this part matches the 4K x 18 density and 20 ns speed with the same PF package footprint.
