7024L55PFI

Memory IC Overview

The Renesas Electronics Corporation 7024L55PFI is a dual-port, asynchronous static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 64 kilobits organized as 4K words by 16 bits. The device features a parallel interface with an access time and write cycle time of 55 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports surface-mount installation in a 100-pin Thin Quad Flat Package (TQFP) measuring 14x14 mm. The component is rated for an industrial operating temperature range from -40°C to +85°C.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous access by two processors
• Asynchronous operation eliminating the need for external clock synchronization
• Parallel data interface supporting standard bus connections
• Industrial-grade thermal rating for extended environmental stability

Memory IC Applications

• High-speed data buffering between microprocessors and peripherals
• Cache memory implementation in embedded control systems
• Data logging and temporary storage in industrial automation controllers
• Real-time signal processing applications requiring low-latency access

Memory IC Procurement Notes

Verify component authenticity through authorized distributors due to discontinuation status. Confirm RoHS compliance requirements as older batches may not meet current environmental standards. Validate package integrity upon receipt, as TQFP pins are susceptible to bending during handling. Ensure design-in compatibility with existing PCB footprints before finalizing procurement plans.

Memory IC Selection Notes

Select this component when dual-processor data sharing is required without complex arbitration logic. The 55ns speed suits moderate-frequency systems where higher-speed alternatives are unnecessary. Consider the 100-pin TQFP package constraints regarding board space and thermal dissipation. Verify that the 4.5V to 5.5V supply range aligns with the system power architecture.

Memory IC Part Context

This part belongs to the Renesas 7024 series of dual-port SRAMs, designed for high-performance data exchange. It succeeds earlier generations with improved pin compatibility and standardized packaging. The 7024L55PFI variant specifically denotes the 55ns speed grade and leaded TQFP package option within the broader family.

Memory IC Replacement Considerations

Official substitutes include the 7024S55G for PGA packaging or the 7024L55PFGI for green RoHS-compliant versions. Cross-reference pinouts carefully when replacing with third-party equivalents to ensure functional parity.
