Description and Introduction

CMOS ASYNCHRONOUS FIFO 2048 x 9, 4096 x 9, 8192 x 9 and 16384 x 9 The IDT7204 is a high-speed, low-power 4K x 9-bit asynchronous FIFO (First-In, First-Out) memory manufactured by Integrated Device Technology (IDT).  

### **Specifications:**  
- **Organization:** 4K x 9-bit (4096 words x 9 bits)  
- **Memory Type:** Asynchronous FIFO  
- **Operating Voltage:** 5V (±10%)  
- **Speed Grades:** Available in multiple speed options (e.g., 25 MHz, 35 MHz)  
- **Access Time:** Typically 25 ns (varies by speed grade)  
- **Power Consumption:** Low power CMOS technology  
- **Operating Temperature Range:** Commercial (0°C to +70°C) or Industrial (-40°C to +85°C)  
- **Package Options:** 28-pin DIP, PLCC, or SOIC  

### **Descriptions:**  
- The IDT7204 is designed for high-speed data buffering applications.  
- It features independent read and write clocks for asynchronous operation.  
- Includes flag signals (Full, Empty, Half-Full) for status monitoring.  
- Supports retransmit function for data recovery.  

### **Features:**  
- **Asynchronous Operation:** No synchronization required between read and write clocks.  
- **Flag Controls:** Full, Empty, and Half-Full flags for efficient data management.  
- **Retransmit Capability:** Allows re-reading of data without external addressing.  
- **Low Power:** CMOS technology ensures minimal power consumption.  
- **Expandable Depth:** Can be cascaded for deeper FIFO configurations.  
- **Industrial-Grade Options:** Available for extended temperature ranges.  

This FIFO is commonly used in data communication, networking, 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

  • CY7C4291-25PC --: Pin-compatible asynchronous FIFO with similar 4K x 9 organization and timing, widely used as a drop-in replacement for IDT7204.
  • SN74ACT7804-25PN --: Asynchronous FIFO memory with comparable depth and speed grade, suitable functional substitute when board-level timing allows.
  • 72V04L25J --: Same FIFO family architecture from the successor brand, offering equivalent 4K x 9 asynchronous FIFO functionality with similar pinout.
  • SN74ACT7804-25FN --: TI FIFO memory in the same 4K x 9 density class with compatible asynchronous interface, suitable functional substitute.
  • CY7C4251-25PC --: Alternative Cypress FIFO with comparable capacity and timing, usable when the primary Cypress option is unavailable.
