Description and Introduction

3.3 VOLT CMOS SyncFIFO 256 x 18, 512 x 18, 1,024 x 18, 2,048 x 18, and 4,096 x 18 The **IDT72V235L15PF** is a high-performance, low-power synchronous FIFO memory device manufactured by Integrated Device Technology (IDT). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**  
- **Density:** 262,144 x 36 (9 Mbit)  
- **Organization:** 32K x 36 or 64K x 18 (configurable)  
- **Operating Voltage:** 3.3V (±10%)  
- **Speed:** 15 ns (66 MHz) access time  
- **I/O Type:** Synchronous, bidirectional  
- **Package:** 120-pin TQFP (Thin Quad Flat Pack)  
- **Operating Temperature Range:** Commercial (0°C to +70°C)  

### **Descriptions:**  
- Designed for high-speed data buffering in networking, telecommunications, and computing applications.  
- Supports **First-In-First-Out (FIFO)** operation with synchronous read and write clocks.  
- Features programmable **Almost Full/Almost Empty** flags for flow control.  
- Includes **Retransmit** capability for data recovery.  
- **Master/Slave** cascading support for depth expansion.  

### **Features:**  
- **Low Power Consumption:** Optimized for power-sensitive applications.  
- **High-Speed Operation:** 66 MHz clock frequency.  
- **Configurable Width:** Can operate as 36-bit, 18-bit, or 9-bit wide.  
- **Flag Options:** Programmable Almost Full/Empty, Half-Full flags.  
- **JTAG Boundary Scan:** Supports IEEE 1149.1-compliant testing.  
- **Industrial-Grade Options:** Available in extended temperature ranges (not for the L15PF variant).  

This information is strictly based on the manufacturer's provided data for the **IDT72V235L15PF** FIFO memory device.

Application Scenarios & Design Considerations

Alternative Part Number

  • CY7C4255V-15AXC --: Pin-compatible synchronous FIFO from a different vendor family with similar 15 ns speed grade and comparable depth/width, often used as a drop-in replacement for IDT 72V235 parts.
  • SN74ACT7805-15FN --: Synchronous FIFO with similar organization and 15 ns access time from TI's ACT FIFO series, suitable functional alternative when IDT parts are unavailable.
  • 72V235L15PF8 --: Renesas acquired IDT and continues to supply the 72V235 FIFO line; this is the same core device sourced from the current manufacturer, ensuring identical specifications and pinout.
