7054S35PRF

Memory IC Overview

The Renesas Electronics Corporation 7054S35PRF is a high-speed, four-port static random-access memory (SRAM) with a capacity of 4K x 8 bits. It features fully asynchronous operation across all four independent ports, allowing simultaneous access to the same memory locations without on-chip hardware arbitration. The device operates on a single 5V power supply and supports battery backup for data retention. It is housed in a 128-pin Thin Quad Flatpack (TQFP) package.

Memory IC Feature Summary

• True FourPort architecture enabling simultaneous read/write access to identical memory addresses from multiple ports
• Fully asynchronous control logic eliminating the need for synchronized clock signals or wait states
• Automatic low-power standby mode activated by chip enable signals to reduce active current consumption

Memory IC Applications

• Multiprocessor systems requiring real-time communication between multiple processors
• High-speed data buffering where concurrent access latency must be minimized
• Systems utilizing master/slave configurations without external arbitration logic

Memory IC Procurement Notes

Verify component authenticity through authorized distributors as this part may be discontinued. Confirm temperature grade and lead-free status against specific datasheet revisions. Check for obsolescence notices from Renesas or IDT prior to procurement planning. Ensure packaging type matches design requirements for surface mount assembly.

Memory IC Selection Notes

Select this component when system architecture demands independent, simultaneous access to shared memory resources. It is suitable for designs avoiding complex external arbitration circuits. Consider power dissipation limits and thermal management for TQFP packages. Verify compatibility with existing TTL-compatible logic levels in the target application environment.

Memory IC Part Context

This device belongs to the IDT/Renesas 7054 family of FourPort SRAMs. It shares architectural similarities with dual-port variants but offers expanded concurrency. The series is designed for applications prioritizing bandwidth and reduced latency over simple point-to-point memory interfaces.

Memory IC Replacement Considerations

Cross-reference with IDT7054S35PRF for functional equivalence. Verify pinout compatibility before substitution. Assess thermal performance differences if replacing with industrial-grade variants.
