72V281L15TFI

FIFOs Memory Overview

The 72V281L15TFI is a synchronous FIFO memory device manufactured by Renesas Electronics. It features a storage capacity of 64K x 9 bits, organized as 576K total bits. The component supports a maximum data rate of 66.7 MHz with a typical access time of 10 ns. It operates on a single 3.3 V power supply, ranging from 3.0 V to 3.6 V, with a maximum supply current of 55 mA. The device is housed in a 64-pin TQFP package and is designed for surface mount installation.

FIFOs Memory Feature Summary

• Supports independent read and write clocks, allowing simultaneous read and write operations without wait states.
• Includes programmable status flags such as Full, Empty, Half-Full, and user-defined Almost-Empty/Almost-Full indicators.
• Features auto power-down mode to minimize standby power consumption during idle periods.
• Provides retransmit capability with fixed low first-word data latency for efficient data handling.

FIFOs Memory Applications

• High-speed data buffering between asynchronous clock domains
• Data acquisition systems requiring precise timing control
• Network interface cards and communication equipment
• Industrial automation controllers

FIFOs Memory Procurement Notes

Verify the exact suffix configuration against official Renesas documentation, as variations exist for temperature grade and packaging. Confirm RoHS compliance status, as some variants may not meet current environmental standards. Check for end-of-life notices or obsolescence warnings before finalizing procurement plans. Ensure ECAD models match the specific pinout and thermal requirements of your design.

FIFOs Memory Selection Notes

Select this component when a synchronous FIFO with 64K depth and 9-bit width is required. Ensure the system voltage aligns with the 3.3 V specification. Consider the 64-pin TQFP package constraints for PCB layout. Verify that the 10 ns access time meets the timing requirements of the connected logic. Compare against other SuperSync family members if different latencies or widths are needed.

FIFOs Memory Part Context

This part belongs to the Renesas 72V281 SuperSync FIFO series, which offers high-performance memory solutions for digital signal processing and communication applications. The series is known for its compatibility with previous generations and its ability to handle high-speed data transfers efficiently. It is designed for industrial and commercial environments, providing reliable performance across specified temperature ranges.

FIFOs Memory Replacement Considerations

Check for direct pin-compatible alternatives within the 72V281 family, such as the 72V281L15TFG, noting differences in RoHS compliance and packaging type. Verify functional equivalence with IDT72V281 variants if sourcing from other manufacturers. Ensure any substitute maintains the same 64K x 9 organization and 3.3 V operating voltage.
