7024L35PFI

Memory IC Overview

The 7024L35PFI is a dual-port static random access memory (SRAM) integrated circuit manufactured by Renesas Electronics. It features a storage capacity of 64 kbit organized as 4K x 16 bits. The device supports parallel interface communication with an access time of 35 ns. It operates on a single power supply voltage ranging from 4.5 V to 5.5 V, with a maximum supply current of 155 mA. The component is designed for surface mount installation in a 100-pin TQFP package and functions within a commercial temperature range of 0°C to +70°C.

Memory IC Feature Summary

• Dual-port architecture enabling simultaneous independent access to memory locations
• Asynchronous operation allowing flexible timing control from either port
• TTL-compatible input and output levels for direct logic interfacing
• Low standby power consumption via automatic power-down control

Memory IC Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded processing systems
• Data acquisition systems requiring concurrent read/write operations
• Industrial control units needing reliable volatile storage

Memory IC Procurement Notes

Verify the specific suffix PFI against official Renesas documentation to confirm the 100-TQFP package and commercial temperature grade. Ensure compatibility with 5V logic families before integration. Check for end-of-life status or discontinuation notices, as older SRAM models may have limited availability or require alternative sourcing strategies for production continuity.

Memory IC Selection Notes

Select this component when a 64-kbit dual-port SRAM with 35-ns speed is required for 5V applications. Compare against the 7024S series for industrial temperature ranges (-40°C to +85°C) if environmental conditions demand it. Consider pinout compatibility with existing PCB layouts designed for 100-pin TQFP packages. Evaluate power dissipation requirements against the 155 mA maximum supply current specification.

Memory IC Part Context

This part belongs to the Renesas 7024/7026 family of dual-port SRAMs, which are widely used in networking and industrial applications. The 7024 series specifically offers 64-kbit density, while the 7026 series provides higher 256-kbit density. These devices are known for their true dual-port capability, allowing two processors to access the same memory simultaneously without conflict through internal arbitration logic.

Memory IC Replacement Considerations

Direct substitutes include the 7024L35JI (84-PLCC package) and 7024L35GB (PGA-84 package) for equivalent electrical performance. For industrial temperature grades, consider the 7024S35 variants. Verify package dimensions and pin assignments before replacement to ensure mechanical fit.
