7028L15PF

Memory IC Overview

The Renesas Electronics Corporation 7028L15PF is a dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 1 megabit, organized as 64K words by 16 bits. The device features an asynchronous parallel interface with a maximum access time of 15 nanoseconds. It operates within a supply voltage range of 4.5 volts to 5.5 volts and supports surface-mount installation in a 100-pin Thin Quad Flat Package.

Memory IC Feature Summary

• Supports simultaneous independent read and write operations at both port A and port B for concurrent data processing.

Memory IC Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded systems
• Data storage in industrial control applications

Memory IC Procurement Notes

Verify component authenticity through authorized distributors due to potential counterfeit risks. Confirm RoHS compliance status and moisture sensitivity level requirements before assembly. Check for specific suffix variations that may indicate different packaging or environmental ratings. Ensure compatibility with existing board designs regarding pinout and voltage levels.

Memory IC Selection Notes

Select this component when dual-port functionality is required for simultaneous access from two distinct controllers. Consider the 15 ns access speed and 1Mb density for moderate performance needs. Evaluate the 100-TQFP package constraints against available PCB real estate. Compare against single-port alternatives if concurrent access is not necessary.

Memory IC Part Context

This part belongs to the Renesas 7028L series of dual-port SRAMs. It shares architectural similarities with other members like the 7025L15PFG8 but differs in memory organization and capacity. The series targets applications requiring high-bandwidth memory sharing between processors or peripherals without external arbitration logic.

Memory IC Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify functional equivalence with any proposed replacements regarding pin configuration, voltage tolerance, and timing parameters.
