7024S55PF

Memory IC Overview

The Renesas Electronics Corporation 7024S55PF is a dual-port, asynchronous SRAM IC with a storage capacity of 64Kb (4K x 16). It features parallel interface and a 55 ns access time. The device operates on a 4.5V to 5.5V supply voltage within an industrial temperature range of -40°C to +85°C. It is housed in a 100-TQFP (14x14) surface-mount package.

Memory IC Feature Summary

• Supports simultaneous independent read/write operations from two separate ports
• Includes on-chip hardware for semaphore signaling and port arbitration
• Provides interrupt flag functionality for efficient data synchronization

Memory IC Applications

• High-speed data buffering between processors
• Network switch memory buffers
• Industrial control system data logging

Memory IC Procurement Notes

Verify the exact suffix against official Renesas documentation to confirm pinout compatibility and electrical specifications. Confirm RoHS compliance status as older variants may differ. Check current production status and lead times directly with authorized distributors or the manufacturer before finalizing procurement plans.

Memory IC Selection Notes

Select this component when true dual-port capability is required for concurrent data access without external arbitration logic. Ensure the 55 ns speed meets system timing requirements. Verify that the 100-pin TQFP package fits the PCB layout constraints and that the industrial temperature range aligns with the operating environment.

Memory IC Part Context

This part belongs to the 7024S series of dual-port static RAMs designed for high-performance applications. It offers a balance of density and speed, utilizing standard CMOS technology. The series is widely used in embedded systems requiring fast, reliable memory sharing between multiple masters.

Memory IC Replacement Considerations

Consult official Renesas substitution guides for compatible alternatives. Verify pin-to-pin compatibility and electrical parameter equivalence if replacing with other dual-port SRAM models.
