Description and Introduction

CMOS ASYNCHRONOUS FIFO 2048 x 9, 4096 x 9, 8192 x 9 and 16384 x 9 The IDT7203L25J is a high-speed, low-power, 9-bit-wide asynchronous FIFO (First-In, First-Out) memory device manufactured by Integrated Device Technology (IDT).  

### **Key Specifications:**  
- **Organization:** 512 x 9  
- **Speed:** 25 ns access time  
- **Operating Voltage:** 5V  
- **Power Consumption:** Low power CMOS technology  
- **Package:** 28-pin PLCC (Plastic Leaded Chip Carrier)  

### **Descriptions and Features:**  
- **Asynchronous FIFO Operation:** Allows independent read and write clocks for flexible data buffering.  
- **High-Speed Performance:** 25 ns access time enables fast data transfers.  
- **Wide Bus Compatibility:** 9-bit-wide data path supports byte-wide applications with parity.  
- **Flag Logic:** Includes Full, Empty, Half-Full, and Programmable Almost Full/Empty flags for efficient memory management.  
- **Low Power Consumption:** CMOS technology ensures reduced power usage.  
- **Industrial Temperature Range:** Suitable for harsh environments.  
- **Retransmit Function:** Allows data to be re-read from the beginning of the FIFO.  
- **Expandable Depth:** Multiple devices can be cascaded for deeper FIFO configurations.  

This device is commonly used in data buffering, communication systems, and digital signal processing applications.

Application Scenarios & Design Considerations

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

Alternative Part Number

  • CY7C429-25JC --: Pin-compatible asynchronous FIFO with similar 2K x 9 organization and 25 ns access time, widely used as a drop-in replacement for the IDT7203 series.
  • SN74ACT7803-25FN --: Asynchronous FIFO in the same 2K x 9 density class with comparable speed grade, suitable functional substitute when layout allows PLCC package.
  • CY7C421-25JC --: Smaller-density FIFO from the same Cypress asynchronous family; acceptable alternative when reduced depth is tolerable and 25 ns timing is required.
  • CY7C4205-25JC --: Pin-compatible synchronous FIFO from Cypress with similar 25 ns speed grade and 4K x 9 organization, a common drop-in replacement for IDT7203 series.
  • 72V03L25J --: Renesas continues the legacy IDT FIFO line under the 72V prefix; same 4K x 9 density and 25 ns speed, direct functional equivalent.
