72841L15PF

FIFOs Memory Overview

The Renesas Electronics Corporation 72841L15PF is a dual synchronous FIFO integrated circuit belonging to the 7200 series. It provides a total storage capacity of 72K bits, organized as two independent 4K x 9 memory blocks within a single package. The device supports a maximum data rate of 100MHz with an access time of 6.5ns. It operates on a supply voltage range of 4.5V to 5.5V and draws a maximum current of 60mA. The component is housed in a 64-pin TQFP (14x14mm) surface-mount package and functions bidirectionally.

FIFOs Memory Feature Summary

• Dual architecture providing two independent 4K x 9 FIFOs with separate control, data, and flag lines for each block.
• Supports flexible configurations including bidirectional operation, width expansion, depth expansion, and priority data buffering.
• Features programmable Almost-Empty and Almost-Full flags alongside standard Empty and Full status indicators.

FIFOs Memory Applications

• Bidirectional data buffering between asynchronous systems
• Width expansion applications requiring parallel data handling
• Two-level priority data buffering scenarios

FIFOs Memory Procurement Notes

Verify RoHS compliance status carefully, as this specific part number is listed as non-compliant in official records. Confirm lead-free availability through alternative suffixes if required by environmental regulations. Check current obsolescence status and last-time-buy dates before finalizing procurement plans.

FIFOs Memory Selection Notes

Select this component when dual independent FIFOs are required without pin-sharing conflicts. Ensure the design accommodates the 64-pin TQFP footprint and 4.5V to 5.5V power requirements. Consider the 6.5ns access time for high-speed interface synchronization needs.

FIFOs Memory Part Context

This device is part of the Renesas 7200 series of synchronous FIFOs. It is functionally equivalent to two 72241 FIFOs combined into one package. The series is designed for applications needing large capacity and design flexibility in a small footprint.

FIFOs Memory Replacement Considerations

Consult manufacturer documentation for direct substitutes. Verify pin compatibility and electrical specifications against alternatives like the 72841L10PFG or other 72841 variants.
