7008L25PFI

Memory IC Overview

The 7008L25PFI 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 an asynchronous parallel interface with a maximum access time of 25 nanoseconds and a write cycle time of 25 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports an industrial operating temperature range from -40°C to +85°C. The component is housed in a 100-lead Thin Quad Flat Pack (TQFP) surface-mount package.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous access to the same memory array by two separate processors or systems.

Memory IC Applications

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

Memory IC Procurement Notes

Verify component authenticity through authorized distributors due to end-of-life status. Confirm RoHS3 compliance for environmental regulations. Check moisture sensitivity level handling requirements during assembly. Validate package dimensions against PCB footprint specifications. Review product change notices for any manufacturing site updates.

Memory IC Selection Notes

Select this component when dual-port functionality is required for concurrent data access. Ensure system voltage matches the 4.5V to 5.5V operational range. Consider the 25ns speed grade for timing constraints. Verify thermal management capabilities for the -40°C to +85°C environment. Compare pin compatibility if replacing older variants in existing designs.

Memory IC Part Context

This part belongs to the IDT 7008L series of high-performance dual-port SRAMs. It succeeds earlier generations like the 7008L15 and 7008L20, offering standardized 25ns performance. The series is designed for applications requiring fast, independent read/write operations without bus contention between multiple masters.

Memory IC Replacement Considerations

Direct substitutes include the 7008L20PFI (20ns speed) and 7008L15PF (15ns speed), provided timing margins allow. Pin-compatible alternatives may exist from other manufacturers, but verify electrical characteristics and logic levels carefully.
