7027S12PFI

Memory IC Overview

The Renesas Electronics Corporation 7027S12PFI is a dual-port static random-access memory (SRAM) device with a storage capacity of 512 kbit, organized as 32k x 16. It features an asynchronous parallel interface with a maximum access time of 12 ns. The component operates within a supply voltage range of 4.5 V to 5.5 V and supports surface-mount installation in a 100-TQFP package.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous access by two processors
• Asynchronous operation for flexible system integration without clock synchronization requirements
• High-speed data transfer capabilities suitable for demanding processing applications

Memory IC Applications

• Network router buffer memory management
• Telecommunications equipment data buffering
• Industrial control systems requiring fast data logging

Memory IC Procurement Notes

Verify the specific suffix 'PFI' against official Renesas documentation to confirm pinout compatibility and package dimensions. Confirm RoHS compliance status as historical records may vary. Check for obsolescence notices or lifecycle changes before finalizing procurement plans.

Memory IC Selection Notes

Select this component when dual-port asynchronous SRAM functionality is required with 12 ns speed performance. Ensure the design accommodates the 100-TQFP package constraints and 5V logic levels. Compare against synchronous alternatives if clock-domain crossing is not a primary constraint.

Memory IC Part Context

This part belongs to the Renesas 7027S series of dual-port SRAMs. It shares architectural similarities with other members like the 7027L25G but differs in speed grade and package type. The series is designed for high-performance memory applications requiring independent port access.

Memory IC Replacement Considerations

Direct substitutes include the IDT7027S12PFI variant. Verify pin-to-pin compatibility and electrical specifications before substitution.
