72V3660L15PF8

FIFOs Memory Overview

The 72V3660L15PF8 is a synchronous first-in, first-out memory device manufactured by Renesas Electronics. It features a storage organization of 4K words by 36 bits, providing a total capacity of 144 kilobits. The component operates with a maximum clock frequency of 66.7 MHz and supports a data rate of 66.7 megabits per second. Access time is specified at 10 nanoseconds. It functions as a unidirectional buffer powered by a single 3.3-volt supply, with voltage limits ranging from 3.15 volts to 3.45 volts. The device is housed in a 128-pin Thin Quad Flat Package.

FIFOs Memory Feature Summary

• Synchronous operation with dedicated read and write clocks for precise data buffering
• Unidirectional data flow architecture designed for specific interface buffering needs
• Supports programmable status flags indicating full and empty memory states
• Integrated First Word Fall Through capability for reduced latency

FIFOs Memory Applications

• Interface bridging between processors operating at different clock speeds
• Network equipment packet buffering and traffic management
• Digital signal processing system data alignment

FIFOs Memory Procurement Notes

This component is officially discontinued and no longer in production. Verification of availability requires checking authorized distributors for remaining stock or surplus inventory. Sourcing should focus on verified suppliers offering traceability documentation. Designers must evaluate long-term supply risks and initiate replacement part qualification immediately to ensure continued manufacturing viability.

FIFOs Memory Selection Notes

Engineers selecting this part must account for its discontinuation status when planning product lifecycles. The 36-bit wide data bus and 4K depth are specific constraints that limit compatibility with narrower or deeper memory requirements. Verify that the 128-pin TQFP package fits the target board layout and that the 3.3V logic levels match the system voltage domain without requiring level shifting.

FIFOs Memory Part Context

The 72V3660L15PF8 belongs to the Renesas 72V series of high-performance synchronous FIFOs. This family is characterized by wide data buses suitable for parallel data interfaces. The L15 suffix typically denotes specific timing and package variations within the broader 72V3660 product line, distinguishing it from other speed grades or pin configurations available in the same series.
