7005L55PFI

Overview

The Renesas Electronics Corporation 7005L55PFI is a static random-access memory (SRAM) integrated circuit featuring an 8K x 8 organization, totaling 64 kbit of storage capacity. It operates as an asynchronous dual-port device with parallel interface technology. The component supports a supply voltage range from 4.5 V to 5.5 V and delivers a maximum access time of 55 ns. Designed for surface-mount installation, it is housed in a 64-TQFP package. The device functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Dual-port architecture enabling independent simultaneous access by two processors
• Asynchronous operation without clock synchronization requirements
• Parallel data interface for direct system bus connectivity

Applications

• High-speed data buffering in embedded systems
• Cache memory implementation in microcontroller architectures
• Real-time data logging in industrial control units

Procurement Notes

Verify component authenticity through authorized distributors due to potential obsolescence status. Confirm RoHS compliance and moisture sensitivity levels prior to integration. Check for specific manufacturing date codes if long-term reliability is critical. Ensure proper ESD handling protocols are followed during assembly. Validate pin compatibility with existing PCB footprints before procurement.

Selection Notes

Select this component when dual-processor communication requires independent read/write ports without arbitration delays. Consider the 55 ns access speed for moderate-frequency applications. Verify that the 64-TQFP package fits the available board space. Ensure the operating environment stays within the specified temperature limits. Compare power consumption against alternative SRAM families for efficiency optimization.
