7027S55PFI

Memory IC Overview

The Renesas Electronics Corporation 7027S55PFI is a dual-port asynchronous static random-access memory (SRAM) integrated circuit. It provides a total storage capacity of 512 kilobits, organized as 32K words by 16 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 4.5 volts to 5.5 volts and supports an industrial operating temperature range from -40°C to +85°C. The component is housed in a 100-pin Thin Quad Flat Package (TQFP) measuring 14x14 millimeters.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous access by two processors
• Asynchronous operation for flexible system integration without clock synchronization

Memory IC Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm exact package variant and environmental compliance status. Confirm current production lifecycle status, as availability may be limited or subject to discontinuation notices. Ensure compatibility with existing board layouts regarding pin assignments and thermal requirements before finalizing procurement orders.

Memory IC Selection Notes

Select this component when dual-port functionality is required for concurrent processor access to shared memory resources. The 55-nanosecond speed class offers a balance between performance and power consumption for general-purpose industrial applications. Consider the 100-pin TQFP package constraints for PCB space and ensure the system voltage aligns with the specified 4.5V to 5.5V operating range.

Memory IC Part Context

This part belongs to the Renesas 7027 series of dual-port SRAM devices. The series typically includes variants with different access speeds and voltage levels. The 'S' suffix generally denotes a specific speed grade within the family, while 'PFI' indicates the lead-free TQFP package configuration. This series is designed for applications requiring high-reliability memory solutions in industrial and automotive environments.

Memory IC Replacement Considerations

Consult official Renesas datasheets for direct pin-compatible replacements with updated speed grades or RoHS compliance if necessary. Verify that any substitute maintains the 32K x 16 organization and dual-port capability.
