7054S45PRFI8

Memory IC Overview

The 7054S45PRFI8 is a high-speed, asynchronous static random-access memory (SRAM) device belonging to the FourPort family. It provides a storage capacity of 32 kilobits, organized as 4K words by 8 bits. The component features four independent ports, each with separate control, address, and data lines, allowing simultaneous and asynchronous access to any memory location without on-chip arbitration. Designed for industrial applications, it operates within a temperature range of -40°C to +85°C and utilizes a 128-pin Thin Quad Flat Package (TQFP).

Memory IC Feature Summary

• Supports fully asynchronous operation across four independent ports.
• Enables simultaneous access to identical memory locations from multiple ports.
• Includes automatic power-down functionality controlled by chip enable signals.

Memory IC Applications

• Systems requiring concurrent read/write operations from multiple masters.
• Industrial control environments necessitating wide operating temperatures.
• Hardware architectures where external port arbitration logic is omitted.

Memory IC Procurement Notes

Verify current availability status as this specific part number may be obsolete or subject to end-of-life notices. Confirm package integrity and moisture sensitivity level handling requirements upon receipt. Ensure compatibility with existing system voltage levels and timing constraints before finalizing procurement decisions.

Memory IC Selection Notes

Select this component when multi-master access to shared memory is required without complex arbitration hardware. Evaluate the trade-off between the four-port capability and the increased pin count compared to standard single-port SRAMs. Consider the industrial temperature rating if deployment occurs in harsh environmental conditions.

Memory IC Part Context

This device is part of the Renesas 7054 series, which specializes in high-performance FourPort SRAM solutions. The series is designed to facilitate efficient data sharing in parallel processing systems. The 'S' designation typically indicates an industrial temperature grade, while 'PRFI8' specifies the lead-free tape and reel packaging configuration.

Memory IC Replacement Considerations

Consult official documentation for direct cross-references. Verify that potential substitutes maintain the four-port architecture and 32Kb capacity. Ensure replacement packages match the 128-pin TQFP form factor and meet the same electrical specifications.
