7005L12PFI

Overview

The Renesas Electronics Corporation 7005L12PFI is a dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 64 kilobits, organized as 8K words by 8 bits. The device features an asynchronous parallel interface with a maximum access time of 12 nanoseconds. It operates within a supply voltage range of 4.5 volts to 5.5 volts and supports surface-mount installation in a 64-pin Thin Quad Flat Package (TQFP). The component is designed for industrial temperature ranges.

Feature Summary

• Supports independent simultaneous read and write operations at both Port A and Port B without bus contention.
• Utilizes asynchronous logic control signals including chip selects, output enables, and write enables for flexible system integration.
• Maintains data integrity through dedicated power-down detection mechanisms that automatically isolate internal circuits during low-voltage conditions.

Applications

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

Procurement Notes

Verify the specific suffix PFI to confirm the TQFP-64 package type and lead-free compliance status. Confirm RoHS directive adherence requirements against current manufacturing standards. Check for moisture sensitivity level handling precautions during assembly. Validate that the source document confirms the component is currently active or identify appropriate obsolescence management strategies if the part is discontinued.

Selection Notes

Select this component when a system requires high-speed dual-port memory with a 12-nanosecond access window. Ensure the design accommodates the 64-TQFP footprint and 4.5V to 5.5V power supply constraints. Consider the industrial temperature range specifications for environmental compatibility. Evaluate pin count and interface complexity against simpler single-port alternatives if dual independence is not required.

Part Context

This component belongs to the Renesas 7005L series of dual-port SRAMs. The series offers various speed grades and packaging options to suit different performance and form-factor requirements. The 7005L12 variant specifically targets applications demanding faster cycle times compared to slower counterparts in the same family, providing enhanced throughput for critical data paths.
