Description and Introduction

CMOS ASYNCHRONOUS FIFO 2048 x 9, 4096 x 9, 8192 x 9 and 16384 x 9 The IDT7203L120DB is a high-speed, low-power 2048 x 9 asynchronous FIFO (First-In, First-Out) memory device manufactured by IDT (Integrated Device Technology).  

### **Specifications:**  
- **Organization:** 2048 x 9-bit  
- **Operating Voltage:** 5V  
- **Speed:** 120 MHz (access time: 10 ns)  
- **Power Consumption:** Low power CMOS technology  
- **Package:** 28-pin PLCC (Plastic Leaded Chip Carrier)  
- **Operating Temperature Range:** Commercial (0°C to +70°C) or Industrial (-40°C to +85°C)  
- **I/O Compatibility:** TTL-compatible inputs and outputs  
- **Retransmit Function:** Allows re-reading of data  
- **Flag Logic:** Programmable Almost Full/Almost Empty flags  

### **Descriptions and Features:**  
- **Asynchronous FIFO:** Independent read and write clocks for flexible data buffering.  
- **High-Speed Operation:** Supports 120 MHz operation for fast data transfer.  
- **Low Power:** CMOS technology ensures low power consumption.  
- **Retransmit Capability:** Enables re-reading of stored data without external logic.  
- **Flag Controls:** Programmable flags (Almost Full/Almost Empty) help prevent overflow/underflow.  
- **Expandable Depth:** Can be cascaded for deeper FIFO configurations.  
- **TTL-Compatible:** Ensures easy interfacing with standard logic devices.  

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

Application Scenarios & Design Considerations

CMOS ASYNCHRONOUS FIFO 2048 x 9, 4096 x 9, 8192 x 9 and 16384 x 9

Alternative Part Number

  • CY7C429-25PC --: Pin-compatible asynchronous FIFO from Cypress with similar 2K x 9 organization and 5V operation; widely available second-source option.
  • SN74ACT7803-25PN --: TI asynchronous FIFO in the same 2K x 9 density class with comparable access timing; good functional substitute when IDT parts are unavailable.
  • 72V03L25J --: Renesas/IDT 3.3V/5V-compatible FIFO with matching 2K x 9 architecture and similar speed grade; direct functional replacement from the same product family lineage.
  • CY7C4205-15AC --: Pin-compatible asynchronous FIFO from Cypress with similar 4K x 9 organization and comparable access speed, widely used as a drop-in replacement for IDT7203 series.
  • SN74ACT7803-20DL --: TI asynchronous FIFO in the same 4K x 9 density class with similar timing characteristics, suitable functional substitute when 120ns speed grade is not critical.
  • 72V03L20J --: Renesas/IDT 3.3V 4K x 9 FIFO from a related family with compatible pinout and function, offering a lower-power alternative to the original 5V device.
