7005L12PF

Overview

The Renesas 7005L12PF is a high-speed, asynchronous dual-port static random-access memory (SRAM) with a density of 64 kilobits. It features an 8K by 8 organization and supports simultaneous independent access from two ports. The device operates on a single 5V power supply and provides a typical access time of 12 nanoseconds. It is housed in a 64-pin Thin Quad Flat Package (TQFP) designed for surface-mount applications.

Feature Summary

• True dual-ported architecture enabling simultaneous reads and writes from separate ports without conflict
• Integrated hardware semaphore signaling and port arbitration logic for automatic synchronization
• Automatic power-down mode controlled by chip enable inputs to minimize standby current consumption
• Full TTL compatibility allowing direct interfacing with standard digital logic families

Applications

• High-performance data buffering in telecommunications equipment
• Cache memory implementation in industrial control systems
• Data storage in network switching infrastructure
• Real-time processing buffers in embedded automotive electronics

Procurement Notes

Verify component authenticity through authorized distributors or official Renesas channels due to the prevalence of counterfeit electronic components. Confirm that the specific package variant matches the required PCB footprint and thermal specifications. Ensure compliance with relevant environmental directives applicable to the target deployment region before finalizing procurement orders.

Selection Notes

Select this component when simultaneous independent access to shared memory is required without external arbitration overhead. The 12-nanosecond speed class suits high-frequency bus architectures. Consider the 64-pin TQFP package constraints regarding board space and thermal dissipation requirements during the initial design phase.
