7027S25PFI8

Memory IC Overview

The 7027S25PFI8 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 features asynchronous parallel interfaces for both ports, allowing independent read and write operations. It supports a supply voltage range of 4.5V to 5.5V and operates within an industrial temperature range of -40°C to +85°C. The component is housed in a 100-lead Thin Quad Flat Package with a 14x14mm footprint.

Memory IC Feature Summary

• Dual-port architecture enabling simultaneous independent access from two distinct systems
• Asynchronous operation eliminating the need for external clock synchronization
• Parallel interface supporting standard data bus widths for straightforward integration

Memory IC Applications

• High-speed data buffering between microprocessors and peripheral devices
• Cache memory implementation in embedded control systems
• Data logging and temporary storage in industrial automation controllers

Memory IC Procurement Notes

Verify the specific suffix PFI8 against official Renesas documentation to confirm package type and moisture sensitivity level. Confirm RoHS compliance status through current datasheets, as older variants may differ. Check for end-of-life notices or obsolescence announcements prior to finalizing procurement plans. Ensure voltage requirements match the target system's power rails.

Memory IC Selection Notes

Select this component when dual independent access is required without complex arbitration logic. Compare access times and power consumption against synchronous alternatives if clock distribution is available. Verify that the 100-pin TQFP package fits the board layout constraints. Consider thermal dissipation capabilities given the operating temperature range and supply voltage specifications.

Memory IC Part Context

This part belongs to the Renesas 7027 series of high-performance dual-port SRAMs. These devices are designed for applications requiring fast data exchange between processors. The series typically offers various speed grades and capacities to suit different performance needs. Renesas continues to support legacy components while transitioning to newer technologies.

Memory IC Replacement Considerations

Check for direct pin-compatible upgrades within the 7027 series offering faster access times. Verify functional equivalence with other dual-port SRAMs from Renesas or IDT. Ensure replacement parts maintain the same voltage and temperature specifications.
