Manufacturer Part Number

72V801L15PFG

Description

High-speed synchronous FIFO memory chip. Supports bi-directional data transfers with 256 words of 9 bits each, in two banks. Offers 4.5K bit total memory. Designed for buffering data at 10ns access time and 66.7MHz data rate. Comes in a 64-lead TQFP package suitable for surface mounting. Can expand depth and width with programmable flag support. Obsolete status.

Operates at standard logic voltage (3 V to 3.6 V).

Low power consumption (up to 40mA max).

Stable performance within 0–70°C ambient.

Allows flexible configuration for expanded memory width/depth.

Application Environments

Used in digital systems requiring high-speed data buffering.

Common in telecommunications network hardware, routers, and switches.

Data acquisition and video processing systems.

Suitable for embedded systems needing temporary data storage between speed mismatched processes.

Not recommended for new designs due to Obsolete status.

Selection Guidelines

Choose this device for systems needing fast, bidirectional FIFO buffering within the specified voltage range.

Check operating temperature and package compatibility with board design.

Verify memory size and speed fit project needs.

For new designs, consider alternative or available non-obsolete models for better long-term support.

Check programmable flag features versus specific application requirements.

Usage Considerations

Check voltage supply compatibility.

Obsolete part: ensure sufficient inventory for longevity or plan migration.

Pay attention to surface mounting requirements for 64-TQFP packages.

Absence of FWFT and retransmit features may impact system design—review FIFO needs.

Program flag functions as required by your data management scheme.

Verify that thermal conditions are within device specifications.

Potential Equivalent/Replacement Models

This model is obsolete—no direct drop-in replacements guaranteed.

Possible alternatives from Renesas or other manufacturers may exist in the FIFO synchronous buffer category (e.g., 72V801 family, 72V721, 72V361 chip families).

For exact match and suitability, contact Ariat-Tech sales team for specific advice and up-to-date inventory on alternatives.

If you need form-fit-function compatibility, always verify pinout, speed, and voltage with alternative options.

If no alternatives match, recommend discussing migration paths with your technical team or Ariat-Tech support.
