723622L15PFG

FIFOs Memory Overview

The Renesas 723622L15PFG is a synchronous dual FIFO memory device featuring two independent 256 x 36 bit buffers. It operates at a maximum clock frequency of 66.7 MHz with an access time of 8 ns. The component supports bidirectional data transfer and requires a single 5.0 V power supply. It is housed in a 120-pin TQFP package and is designated as an obsolete product by the manufacturer.

FIFOs Memory Feature Summary

• Dual independent synchronous FIFO structures for simultaneous bidirectional data buffering
• Hardware support for programmable Almost-Full and Almost-Empty status flags
• First Word Fall Through (FWFT) timing mode capability
• TTL-compatible logic levels for standard 5V system integration

FIFOs Memory Applications

• High-speed data buffering between asynchronous microprocessor buses
• Network interface controller data staging
• Digital signal processing pipeline synchronization

FIFOs Memory Procurement Notes

This component is officially discontinued and no longer in active production. Verification of availability is restricted to surplus or secondary market sources only. Buyers must confirm the authenticity of existing stock and review End-of-Life notifications for potential obsolescence risks before procurement consideration.

FIFOs Memory Selection Notes

Designers should evaluate alternative components from current Renesas families due to the discontinuation status. Compatibility checks regarding pinout, voltage levels, and timing parameters are essential when migrating to successor devices. Legacy design maintenance may require careful sourcing strategies given the limited supply chain support.

FIFOs Memory Part Context

The 723622L15PFG belongs to the Renesas 723622 series of high-performance synchronous FIFOs. This series was engineered for applications requiring wide data paths and fast access times. The specific model provides dual-port functionality within a compact surface-mount package, serving as a bridge between different speed domains in complex digital systems.

FIFOs Memory Replacement Considerations

Consult official Renesas documentation for direct cross-reference part numbers. Verify that any substitute maintains identical pin configurations and electrical specifications to ensure board-level compatibility without redesign.
