7008S25PFI8

Memory IC Overview

The Renesas Electronics Corporation 7008S25PFI8 is a 512Kbit (64K x 8) asynchronous dual-port static random-access memory (SRAM) IC. It features a parallel interface with a 25 ns access time and operates on a single 5V power supply ranging from 4.5V to 5.5V. The component is housed in a 100-lead Thin Quad Flat Package (TQFP) measuring 14x14 mm, designed for surface-mount installation.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous access by two processors
• Asynchronous operation without clock synchronization requirements
• Parallel data interface supporting block-based data transfer

Memory IC Applications

• High-speed data buffering between independent processing units
• Cache memory implementation in embedded systems
• Data storage in telecommunications equipment requiring concurrent read/write operations

Memory IC Procurement Notes

Verify the specific package variant and lead configuration against the official datasheet before integration. Confirm that the 100-TQFP footprint matches the target PCB design. Ensure voltage levels align with the 4.5V to 5.5V operating range. Check for any RoHS compliance status updates or environmental restrictions applicable to this component in the destination market.

Memory IC Selection Notes

Select this component when a system requires independent dual access to shared memory without bus contention. The 25 ns speed suits moderate-to-high frequency applications. The 100-TQFP package offers a balance of pin count and thermal performance for surface-mount assembly. Consider the 5V logic compatibility if interfacing with legacy digital circuits.

Memory IC Part Context

This device belongs to the 7008S series of asynchronous dual-port SRAMs manufactured by Renesas Electronics. The series provides non-volatile-like reliability with volatile speed, utilizing standard CMOS technology. The 7008S25PFI8 specifically denotes the 25 ns speed grade within the 512Kbit capacity family.

Memory IC Replacement Considerations

Check for direct cross-reference part numbers from IDT or Microchip, as Renesas acquired these product lines. Verify pinout compatibility and electrical specifications before substitution.
