7027L55PFI8

Memory IC Overview

The 7027L55PFI8 is a dual-port static random-access memory (SRAM) integrated circuit manufactured by Renesas Electronics Corporation. It provides a storage capacity of 512 kilobits, organized as 32K words by 16 bits. The device utilizes an asynchronous 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 surface-mount installation in a 100-pin Thin Quad Flat Package (TQFP) measuring 14x14 mm. The component is rated for an ambient operating temperature range from -40°C to +85°C.

Memory IC Feature Summary

• Supports simultaneous independent read and write operations at both Port A and Port B without bus contention.

Memory IC Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in industrial control systems
• Data logging in automotive electronic modules

Memory IC Procurement Notes

Verify the RoHS compliance status carefully, as this specific part number may not meet current environmental directives. Confirm the package marking and date code against official Renesas documentation to ensure authenticity. Check for any product discontinuance notices or end-of-life notifications that may affect long-term availability and support.

Memory IC Selection Notes

Select this component when a 5V logic interface is required for dual-port memory applications. Ensure the system design accommodates the 100-TQFP footprint and thermal requirements. Compare performance metrics against newer series if lead times are critical, as older variants may have limited production runs.

Memory IC Part Context

This device belongs to the 7027L family of high-performance dual-port SRAMs. It is designed for applications requiring fast, non-blocking data transfer between two independent processors or buses. The 55ns speed grade offers a balance between performance and power consumption for standard 5V logic environments.

Memory IC Replacement Considerations

Direct replacement options include the 7027L20PFGI, which offers faster access times but requires verification of pin compatibility and electrical characteristics.
