7005L20PFI

Overview

The Renesas Electronics Corporation 7005L20PFI is a static random access memory device featuring 64 kbit storage capacity organized as 8k x 8. It operates with an asynchronous parallel interface and provides a maximum access time of 20 ns. The component supports a supply voltage range from 4.5 V to 5.5 V, with a maximum power consumption of 280 mA. Designed for surface mount installation, it is housed in a TQFP-64 package. The device functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Dual-port architecture enabling independent simultaneous access by two processors
• Asynchronous operation compatible with standard logic interfaces
• High-speed data transfer capabilities suitable for real-time processing applications

Applications

• Data buffering in high-performance computing systems
• Cache memory implementation in embedded controllers
• Real-time signal processing hardware acceleration

Procurement Notes

Verify current availability status as the component may be discontinued or subject to limited supply constraints. Confirm RoHS compliance requirements against specific project standards, noting that certain variants may not meet current environmental directives. Validate package integrity and moisture sensitivity levels prior to assembly to ensure reliable soldering processes during manufacturing.

Selection Notes

Select this component when dual-port functionality is required for concurrent processor access without arbitration overhead. Ensure system voltage rails align with the specified 4.5 V to 5.5 V operational range. Consider the TQFP-64 footprint for PCB layout compatibility and verify thermal management strategies are adequate for the specified power dissipation characteristics under maximum load conditions.

Part Context

This part belongs to the Renesas 7005L series of dual-port SRAMs, designed for applications requiring fast, independent read/write access from two separate masters. The series offers various speed grades and packaging options to accommodate different performance and form factor requirements in industrial and commercial electronic designs.

Replacement Considerations

Check for direct pin-compatible upgrades such as the 7005L20PFGI variant, which may offer updated environmental compliance while maintaining functional equivalence. Verify electrical parameter alignment before substitution.
