Description and Introduction

CMOS SyncBiFIFOO 256 x 36 x 2, 512 x 36 x 2, 1024 x 36 x 2 The **IDT723642L15PF** is a high-speed, low-power, synchronous FIFO (First-In, First-Out) memory device manufactured by **Integrated Device Technology (IDT)**. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Density:** 64K x 36 (2,304K bits)  
- **Organization:** 65,536 words × 36 bits  
- **Speed:** 15 ns access time (15PF speed grade)  
- **Operating Voltage:** 3.3V (±10%)  
- **Operating Temperature Range:** Commercial (0°C to +70°C)  
- **Package:** 120-pin TQFP (Thin Quad Flat Pack)  
- **I/O Type:** 5V-tolerant inputs, 3.3V outputs  

### **Descriptions:**
- **Synchronous FIFO:** Supports simultaneous read and write operations with independent clocks.  
- **Low Power:** Optimized for power-sensitive applications.  
- **High Performance:** 15 ns access time ensures fast data transfers.  
- **Flag Logic:** Features programmable Almost Full/Almost Empty flags for flow control.  
- **Retransmit Function:** Allows resetting the read pointer to the start of data for retransmission.  

### **Features:**
- **Dual-Clock Operation:** Independent read and write clocks for asynchronous data transfer.  
- **Programmable Flags:** Configurable Almost Full/Almost Empty thresholds.  
- **Expandable Depth and Width:** Supports expansion in depth (cascading) and width (via external logic).  
- **5V-Tolerant Inputs:** Enables interfacing with 5V logic systems.  
- **Low Standby Current:** Reduces power consumption in idle mode.  
- **Industrial-Grade Options:** Available in extended temperature ranges for harsh environments.  

This FIFO is commonly used in networking, telecommunications, and data buffering applications where high-speed, reliable data storage and retrieval are required.

Application Scenarios & Design Considerations

Alternative Part Number

  • CY7C4265V-15ASXC --: Pin-compatible synchronous FIFO from Cypress with similar 15 ns speed grade and comparable density, widely available as a drop-in functional substitute.
  • SN74ACT7808-15PAG --: TI synchronous FIFO in the same family class with 15 ns access time and similar organization, suitable for replacing the IDT FIFO in buffering applications.
  • 72V275L15PF --: Renesas (formerly IDT) high-speed FIFO with matching 15 ns speed and similar architecture, offering a close functional match with continued long-term availability.
  • CY7C43642-15AC --: Cypress second-source FIFO with matching 64K x 36 architecture and 15 ns speed grade, pin-compatible with the IDT723642 in most designs.
  • SN74ACT7808-15PQ --: TI FIFO in the same 15 ns performance class with similar depth/width organization; requires pinout verification but is a viable functional substitute.
  • 72V3642L15PF --: Renesas (formerly IDT) FIFO family member with equivalent 64K x 36 density and 15 ns timing, offering a direct functional replacement path.
