Description and Introduction

CMOS ASYNCHRONOUS FIFO 256 x 9, 512 x 9, 1,024 x 9 The IDT7202LA65J is a high-speed, low-power, 2048 x 9-bit asynchronous FIFO (First-In, First-Out) memory manufactured by Integrated Device Technology (IDT).  

### **Specifications:**  
- **Memory Organization:** 2048 x 9-bit  
- **Operating Voltage:** 5V  
- **Speed:** 65 ns access time  
- **Power Consumption:** Low power CMOS technology  
- **Operating Temperature Range:** Commercial (0°C to +70°C)  
- **Package:** 28-pin PLCC (Plastic Leaded Chip Carrier)  
- **I/O Compatibility:** TTL-compatible inputs and outputs  
- **Asynchronous Operation:** Independent read and write clocks  
- **Full/Empty Flags:** Indicates FIFO status  
- **Retransmit Capability:** Allows resetting the read pointer to the start of memory  

### **Descriptions and Features:**  
- **High-Speed Operation:** Supports fast data transfer with a 65 ns access time.  
- **Low Power Consumption:** Optimized for power efficiency in CMOS technology.  
- **Asynchronous FIFO:** Enables independent read and write operations without a common clock.  
- **9-Bit Wide Data Bus:** Suitable for byte-wide data storage with parity or control bits.  
- **Status Flags:** Includes Full, Empty, and Half-Full flags for efficient FIFO management.  
- **Expandable Depth:** Can be cascaded for deeper FIFO configurations.  
- **Industrial-Standard Pinout:** Compatible with other FIFO devices for easy replacement.  

This FIFO is commonly used in buffering applications, data rate matching, and communication systems.  

(Note: Always verify datasheets for the latest specifications.)

Application Scenarios & Design Considerations

CMOS ASYNCHRONOUS FIFO 256 x 9, 512 x 9, 1,024 x 9

Alternative Part Number

  • CY7C421-65JC --: Pin-compatible asynchronous FIFO in the same 32-pin PLCC package with comparable 65 ns access time, widely used as a drop-in replacement for the IDT7202 family.
  • SN74ACT7802-65FN --: Asynchronous FIFO with similar 512x9 organization and 65 ns speed grade, offering equivalent functionality in a PLCC package.
  • CY7C429-65JC --: Alternate Cypress FIFO with matching 65 ns timing and PLCC footprint, suitable when the primary Cypress option is unavailable.
