7005L15PFI8

Overview

The Renesas Electronics Corporation 7005L15PFI8 is a dual-port static random-access memory (SRAM) IC with a storage capacity of 64 Kbit, organized as 8K x 8. It features an asynchronous parallel interface and a typical access time of 15 ns. The device operates on a single power supply voltage ranging from 4.5 V to 5.5 V, with a maximum supply current of 280 mA. It is housed in a 64-lead Thin Quad Flat Package (TQFP) measuring 14x14 mm and supports surface-mount installation. The component functions within a temperature range of -40°C to +85°C.

Feature Summary

• Dual-port architecture enabling independent read/write operations on separate ports
• Asynchronous operation for flexible timing integration
• Single 5V power supply compatibility

Applications

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

Procurement Notes

Verify the exact package marking and date code against the manufacturer's latest documentation, as this part may be subject to discontinuation notices or lifecycle changes. Confirm that the 64-TQFP footprint matches your PCB design constraints. Ensure compliance with RoHS status requirements, as older batches may not meet current environmental standards. Cross-reference the specific suffix 'I8' to confirm internal revision details before finalizing procurement orders.

Selection Notes

Select this component when a non-volatile-free, high-speed temporary storage solution is required for 8-bit wide data paths. The 15 ns access time suits applications needing low-latency data handling. Consider the dual-port capability if simultaneous host and peripheral access is necessary. Evaluate the 64-TQFP package size against available board space and thermal dissipation requirements for the target environment.

Part Context

This device belongs to the 7005L series of dual-port SRAMs manufactured by Renesas Electronics. It shares architectural similarities with other members like the 7005L25PFI but offers faster access speeds. The series is designed for general-purpose memory applications where data integrity and speed are critical. It complements synchronous FIFO solutions by providing true dual-port independence without clock synchronization constraints.

Replacement Considerations

Direct substitutes include the IDT7005L15PFI8. Verify pinout compatibility and electrical specifications before substitution.
