7008L25PFI8

Memory IC Overview

The 7008L25PFI8 is a dual-port static random-access memory (SRAM) integrated circuit manufactured by Renesas Electronics Corporation. It provides a total storage capacity of 512 kilobits, organized as 64K words by 8 bits. The device features asynchronous parallel interface operation with a maximum access time of 25 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports an industrial temperature range from -40°C to +85°C. The component is housed in an 84-pin Thin Quad Flat Package (TQFP) with dimensions of 14x14 mm.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous access to the same memory array
• Asynchronous parallel interface for straightforward integration into standard logic systems
• Industrial-grade operational capability across extended temperature ranges

Memory IC Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded processing systems
• Data acquisition systems requiring rapid temporary storage

Memory IC Procurement Notes

Verify component authenticity through authorized distributors due to end-of-life status. Confirm RoHS compliance requirements against specific project standards, as legacy variants may differ. Validate package integrity upon receipt, ensuring no pin damage occurred during handling or shipping. Cross-reference datasheet revisions to ensure compatibility with existing design specifications.

Memory IC Selection Notes

Select this component when dual-port functionality is required for concurrent read/write operations without external arbitration logic. Consider the 512Kb capacity and 25ns speed as primary constraints. Evaluate the TQFP-84 package suitability for PCB layout density. Compare against single-port alternatives if simultaneous access is unnecessary to reduce cost.

Memory IC Part Context

This part belongs to the Renesas 7008L series of dual-port SRAMs. It shares architectural similarities with other members like the 7008L20JGI8 but differs in access speed and package type. The series is designed for applications demanding high-bandwidth memory access with independent port control.

Memory IC Replacement Considerations

Direct substitutes include the 7008L20JGI8, which offers similar capacity but faster 20ns access time in an 84-PLCC package. Verify pinout compatibility and voltage levels before substitution.
