72V281L15TF

FIFOs Memory Overview

The 72V281L15TF is a synchronous FIFO memory device manufactured by Renesas Electronics. It features a storage capacity of 576K bits, organized as 64K words by 9 bits. The component supports a maximum data rate of 66.7 MHz with an access time of 10 ns. It operates on a supply voltage ranging from 3 V to 3.6 V and draws a maximum supply current of 55 mA. The device is housed in a 64-TQFP package (10x10 mm) and is designed for surface mount installation.

FIFOs Memory Feature Summary

• Supports independent read and write clocks allowing simultaneous operations
• Includes programmable flags for empty, full, half-full, almost-empty, and almost-full status
• Features fixed low first word data latency and retransmit operation capabilities
• Enables easy expansion in both depth and width configurations

FIFOs Memory Applications

• Data buffering in graphics systems
• Local area network interfaces
• Interprocessor communication links

FIFOs Memory Procurement Notes

Verify RoHS compliance status as sources indicate non-compliance. Confirm moisture sensitivity level 3 handling requirements. Check for end-of-life discontinuation notices from the manufacturer. Ensure availability of valid datasheets for design integration. Validate package dimensions against PCB footprint specifications.

FIFOs Memory Selection Notes

Select this part for applications requiring 64K x 9 synchronous buffering at 66.7 MHz. Consider the 10 ns access time for timing constraints. Verify 3.3 V power supply compatibility. Evaluate TQFP-64 package suitability for assembly processes. Compare against other 72V281 variants for packaging or temperature range differences.

FIFOs Memory Part Context

This component belongs to the 72V281 SuperSync FIFO family. It serves as a 3.3 V version of legacy 5 V devices like the 72291. The series offers functionally compatible performance with reduced power consumption. It maintains pin compatibility with related IDT72V21x1 parts.

FIFOs Memory Replacement Considerations

IDT72V281L15TF is listed as an alias. Verify functional equivalence before substitution. Other 72V281 variants may differ in packaging or temperature grade.
