72V281L15PFGI

FIFOs Memory Overview

The 72V281L15PFGI is a 3.3V CMOS SuperSync FIFO memory device manufactured by Renesas Electronics. It features a storage capacity of 32K x 18 bits, organized as 32,768 words of 18-bit width. The component operates within a supply voltage range of 3.0 V to 3.6 V and supports data rates up to 66.7 MHz with a 10 ns access time. It utilizes independent read and write clocks for asynchronous operation and is housed in a 64-pin TQFP package.

FIFOs Memory Feature Summary

• SuperSync architecture with fixed low first word data latency
• Independent read and write clock inputs for dual-clock operation
• Programmable status flags including empty, full, half-full, almost-empty, and almost-full indicators
• Retransmit capability with fixed latency period

FIFOs Memory Applications

• Data buffering in graphics systems
• Interprocessor communication interfaces
• Local area network data handling
• High-speed digital signal processing buffers

FIFOs Memory Procurement Notes

Verify RoHS compliance status and moisture sensitivity level (MSL 3) prior to assembly. Confirm package type is 64-TQFP and check for obsolescence notices or PCN updates from Renesas. Ensure ESD protection measures are followed during handling due to CMOS technology characteristics.

FIFOs Memory Selection Notes

Select this part when 18-bit wide data paths are required alongside high-speed synchronous buffering. Compare against the 72V291 series if 9-bit width suffices, as pin compatibility exists. Verify that the 3.3V operating voltage aligns with system power rails and that the 64-pin TQFP footprint fits the PCB layout constraints.

FIFOs Memory Part Context

This component belongs to the 72V281 SuperSync FIFO family, designed as a low-power 3.3V replacement for older 5V devices like the 72291. It maintains functional compatibility while eliminating the frequency select pin, simplifying clock management. The family emphasizes reduced standby power through auto power-down features.

FIFOs Memory Replacement Considerations

The IDT72V281L15PFGI is an alias for this part number. For 9-bit width applications, the 72V291L15 series offers pin-compatible alternatives. Check Renesas documentation for specific suffix variations regarding lead-free status or packaging differences.
