72851L25PF

FIFOs Memory Overview

The Renesas 72851L25PF is a synchronous dual-port FIFO memory device. It features a storage capacity of 4K words by 9 bits, organized as two independent 4K x 9 ports. The component supports bidirectional data transfer and operates with a maximum clock frequency of 40 MHz. It utilizes a 64-pin TQFP package and functions within a supply voltage range of 4.5 V to 5.5 V.

FIFOs Memory Feature Summary

• Synchronous dual-port architecture enabling simultaneous read and write operations on separate ports.
• Bidirectional data bus capability allowing flexible data flow direction for each port.
• Integrated programmable flags indicating full, empty, and half-full memory states.

FIFOs Memory Applications

• Data buffering in high-speed digital signal processing systems
• Interface bridging between asynchronous logic components
• Temporary storage in telecommunications equipment

FIFOs Memory Procurement Notes

Verify the specific suffix 'PF' against official Renesas documentation to confirm the exact package type and temperature grade. Ensure compatibility with existing board layouts regarding the 64-pin TQFP footprint. Confirm that the 4.5V to 5.5V operating voltage aligns with the target system power rails before procurement.

FIFOs Memory Selection Notes

Select this component when a synchronous interface with moderate depth is required for 9-bit data paths. Compare against the 72851L15 series if faster access times are necessary, noting potential differences in performance specifications. Consider the 72801 series for alternative word widths or depths if the 4K x 9 configuration does not meet system requirements.

FIFOs Memory Part Context

This part belongs to the Renesas 72851L family of synchronous FIFO memories. These devices are designed for applications requiring reliable data buffering between different clock domains or speeds. The family typically offers various speed grades and organization options to suit diverse embedded memory needs.

FIFOs Memory Replacement Considerations

Check for direct substitutes such as the IDT72851L25PF, which shares identical electrical characteristics and pinout. Verify availability of equivalent parts from other manufacturers offering synchronous FIFOs with similar 4K x 9 organization and 40 MHz operation capabilities.
