72V851L15TFG

FIFOs Memory Overview

The 72V851L15TFG is a synchronous dual-port FIFO memory device manufactured by Renesas Electronics. It features a storage capacity of 144K bits, organized as 8K words by 9 bits per word, doubled for dual-port operation. The component supports a maximum data rate of 66.7MHz with a 10ns access time. It operates on a single 3.3V power supply within a voltage range of 3V to 3.6V. The device utilizes a 64-pin TQFP package and includes programmable flags for status monitoring.

FIFOs Memory Feature Summary

• Dual-clock architecture supporting asynchronous or coincident read and write operations
• Programmable empty, full, almost-empty, and almost-full flags
• First Word Fall Through (FWFT) timing option available
• Output enable control places the data bus in a high-impedance state

FIFOs Memory Applications

• Data buffering in optical disk controllers
• Interprocessor communication interfaces
• Local Area Network (LAN) data handling
• High-speed digital signal processing systems

FIFOs Memory Procurement Notes

Verify the specific suffix 'TFG' against official Renesas documentation to confirm package dimensions and moisture sensitivity level. Confirm RoHS compliance status as historical records vary. Check for End-of-Life notices or Product Change Notifications that may affect long-term availability. Ensure the ordering part number matches the exact speed grade and package variant required for your design.

FIFOs Memory Selection Notes

Select this component when a dual-clock FIFO with 9-bit width is required for 3.3V logic systems. Compare against the 72V851L15PF if tape-and-reel packaging is preferred over tubes. Consider the 72V851L20 series if slower speeds are acceptable but wider availability is needed. Verify temperature range requirements, as industrial grades (-40°C to +85°C) differ from commercial grades.

FIFOs Memory Part Context

This part belongs to the 72V851 family of synchronous FIFOs. It shares architectural similarities with other members like the 72V851L15PF and 72V851L20PF. The primary distinction lies in the package type and manufacturing lot specifications. It serves as a buffer solution for high-speed data transfer between asynchronous domains.

FIFOs Memory Replacement Considerations

The 72V851L15PF is a functional equivalent with identical electrical characteristics but differs in packaging format. Verify pin compatibility and mechanical fit before substitution. No direct drop-in replacements with different packages are officially confirmed without schematic review.
