7007L55PFI8

Memory IC Overview

The Renesas Electronics Corporation 7007L55PFI8 is a dual-port, asynchronous static random-access memory (SRAM) integrated circuit. It provides a total storage capacity of 256 kilobits, organized as 32K words by 8 bits. The device features a parallel interface with a maximum access time and write cycle time of 55 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports an industrial operating temperature range from -40°C to +85°C. The component is housed in a surface-mount 100-TQFP package measuring 14x14 mm.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous access by two processors
• Asynchronous operation eliminating the need for external clock synchronization
• Parallel data interface supporting standard high-speed memory bus connections

Memory IC Applications

• High-performance embedded systems requiring concurrent data access
• Industrial control units operating in extended temperature environments
• Telecommunications equipment utilizing asynchronous memory buffering

Memory IC Procurement Notes

Verify the specific suffix PFI8 against official Renesas documentation to confirm the exact package type and moisture sensitivity level. Confirm RoHS compliance status as older variants may not meet current environmental standards. Check for active obsolescence notices or production discontinuation announcements directly from the manufacturer before finalizing procurement plans.

Memory IC Selection Notes

Select this component when a design requires independent dual-port access without complex arbitration logic. Ensure the system power supply strictly maintains the 4.5V to 5.5V range to guarantee reliable operation. Verify that the PCB layout accommodates the 100-pin TQFP footprint and meets thermal dissipation requirements for the specified industrial temperature grade.

Memory IC Part Context

This part belongs to the Renesas 7007L series of dual-port SRAMs, designed for applications needing fast, non-blocking memory access. The series typically offers various speed grades and capacities. The 7007L55 variant specifically targets mid-range performance needs with a 55ns access time, balancing speed and power consumption for general-purpose asynchronous memory tasks.

Memory IC Replacement Considerations

Consult official Renesas cross-reference guides for verified substitutes. Potential alternatives include other members of the 7007L family with compatible pinouts and electrical characteristics. Ensure any replacement matches the 100-TQFP package dimensions and voltage specifications.
