72215LB15PF8

Overview

The Renesas Electronics Corporation 72215LB15PF8 is a synchronous First-In, First-Out (FIFO) memory device belonging to the 7200 series. It features a storage capacity of 4K words by 18 bits, providing a total density of 72 kilobits. The component supports a maximum data rate of 66.7 MHz with an access time of 15 nanoseconds. It operates within a supply voltage range of 4.5 V to 5.5 V and draws a maximum supply current of 60 mA. The device is housed in a 64-pin Thin Quad Flat Package (TQFP) with dimensions of 14 mm by 14 mm.

Feature Summary

• Synchronous FIFO architecture with independent read and write clock domains for asynchronous data buffering.
• Configurable word width and depth expansion capabilities to adapt to specific system memory requirements.
• Programmable status flags including full, empty, and half-full indicators for flow control management.

Applications

• Data buffering in high-speed serial communication interfaces
• Interprocessor communication between microprocessors and digital signal processors
• Network interface card data staging

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential counterfeit risks. Confirm RoHS compliance status and moisture sensitivity level handling requirements prior to assembly. Check for end-of-life notices or obsolescence warnings as availability may be restricted. Ensure packaging specifications match production line requirements for surface mount technology integration.

Selection Notes

Select this component when a 18-bit wide synchronous FIFO is required for systems operating at 66.7 MHz. Compare against wider bus alternatives if data path alignment differs. Consider the 64-pin TQFP package constraints for PCB layout density. Evaluate power consumption limits against available thermal dissipation solutions in the target enclosure design.

Part Context

This part belongs to the Renesas 7200 series of high-performance synchronous FIFOs, previously manufactured under IDT branding. The series is designed for applications requiring reliable data buffering between components operating at different speeds. The 72215 variant specifically addresses mid-density memory needs with 18-bit word widths, bridging the gap between narrower 9-bit and wider 36-bit configurations.

Replacement Considerations

Direct substitutes include the IDT72215LB15PF8. Verify pinout compatibility and electrical characteristics before substitution. Alternative families may require logic level translation or firmware adjustments.
