72851L25PFI

FIFOs Memory Overview

The Renesas 72851L25PFI is a dual synchronous FIFO memory device featuring two independent 8K x 9 bit memory arrays within a single package. It operates at a maximum clock frequency of 40 MHz with a 15 ns access time, supporting bi-directional data transfer. The component utilizes a standard 5.0 V power supply and is housed in a 64-pin TQFP (14x14 mm) surface-mount package.

FIFOs Memory Feature Summary

• Dual synchronous architecture providing two independent 8K x 9 FIFOs
• Bi-directional bus capability for flexible data handling
• High-speed operation up to 40 MHz

FIFOs Memory Applications

• FPGA buffer management
• High-speed data acquisition systems
• Real-time signal processing interfaces

FIFOs Memory Procurement Notes

Verify the exact suffix 'PFI' against official Renesas documentation to confirm pinout and package dimensions. Confirm RoHS compliance status as distributor listings may vary. Check for end-of-life notices or obsolescence warnings before finalizing procurement plans.

FIFOs Memory Selection Notes

Select this component when dual independent synchronous FIFOs are required in a compact footprint. Ensure system timing requirements align with the 15 ns access speed. Verify voltage compatibility with the specified 5.0 V operating range.

FIFOs Memory Part Context

This part belongs to the Renesas 72851L series of dual synchronous FIFOs. It is functionally equivalent to integrating two separate 72251 FIFO units into one package, offering consolidated control logic and reduced board space for high-density designs.

FIFOs Memory Replacement Considerations

Check for direct cross-references from IDT or other manufacturers offering identical 8K x 9 dual synchronous FIFO specifications. Verify pin compatibility and electrical parameters before substitution.
