7007L55PF8

Memory IC Overview

The Renesas Electronics Corporation 7007L55PF8 is a dual-port static random access memory (SRAM) integrated circuit. It features a storage capacity of 256 kbit organized as 32K x 8 bits. The device utilizes an asynchronous parallel interface with a maximum access time of 55 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and supports surface-mount installation in an 80-TQFP package measuring 14x14 mm. The component functions reliably across a standard commercial temperature range from 0°C to +70°C.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations by two separate masters.
• Asynchronous parallel interface for straightforward integration into legacy or high-speed data bus systems.
• Volatile SRAM technology providing fast, non-destructive read capabilities with low power consumption.

Memory IC Applications

• High-performance embedded systems requiring rapid data buffering.
• Industrial control units needing reliable temporary data storage.
• Telecommunications equipment utilizing parallel memory interfaces.

Memory IC Procurement Notes

This component is officially designated as obsolete by the manufacturer. Procurement is restricted to remaining stock held by distributors or secondary market suppliers. Verify authenticity carefully due to potential availability of refurbished or counterfeit units. Confirm RoHS compliance status, as older batches may not meet current environmental regulations. Lead times are unpredictable and dependent on third-party inventory levels rather than direct manufacturing schedules.

Memory IC Selection Notes

Engineers should evaluate this part only if specific legacy compatibility with the 7007L series is required. Consider modern alternatives offering improved pin compatibility or enhanced performance metrics. Verify that the 80-TQFP footprint matches existing PCB designs. Assess whether the 55 ns access time meets current system timing requirements. Check for updated replacement components within the same product family that maintain functional equivalence.

Memory IC Part Context

The 7007L55PF8 belongs to the broader 7007L series of dual-port SRAMs produced by Renesas Electronics. This series is designed for applications requiring shared memory access between multiple processors or controllers. The device represents a transition point in Renesas's memory portfolio, bridging older IDT-derived technologies with newer Renesas-specific offerings. It serves niche markets where dual-port functionality is critical for system architecture.

Memory IC Replacement Considerations

Official substitutes include the IDT7007L55PF8, which shares identical specifications and pinout configurations. Other compatible options within the 7007L family may offer variations in package type or speed grades. Always verify electrical parameters and mechanical dimensions before substitution to ensure seamless integration without redesigning the host system.
