7034S20PF

Memory IC Overview

The Renesas Electronics Corporation 7034S20PF is a high-speed, asynchronous dual-port static random-access memory (SRAM) device. It features a storage organization of 4K words by 18 bits, providing a total capacity of 72 kilobits. The component supports parallel interface operations with a maximum access time of 20 nanoseconds. It operates on a single 5V power supply and is housed in a 100-pin Thin Quad Flat Package (TQFP). This memory IC is designed for applications requiring simultaneous independent access from two separate ports.

Memory IC Feature Summary

• True dual-port architecture enabling simultaneous read and write operations from both ports without conflict
• On-chip hardware support for semaphore signaling to manage data integrity between ports
• Integrated port arbitration logic and interrupt flag capabilities for efficient bus management
• Fully asynchronous operation allowing flexible timing control from either memory port

Memory IC Applications

• Stand-alone 72K-bit dual-port memory systems
• Master/Slave configurations for wider word-length data processing
• High-speed data buffering in telecommunications equipment
• Real-time signal processing applications requiring low-latency access

Memory IC Procurement Notes

Verify the specific suffix PF indicates the 100-pin TQFP package configuration. Confirm RoHS compliance status as older variants may differ. Check for end-of-life notifications or obsolescence notices from Renesas. Ensure compatibility with existing PCB footprints for 100-pin QFP packages. Validate moisture sensitivity levels for reflow soldering processes.

Memory IC Selection Notes

Select this component when a true dual-port SRAM with 18-bit word width is required. Compare against single-port alternatives if only one access path is needed. Consider the 20ns access speed relative to system clock requirements. Evaluate the 100-pin package size against available board space. Verify voltage tolerance matches the 5V system design constraints.

Memory IC Part Context

This part belongs to the IDT/Renesas 7034 series of high-speed dual-port SRAMs. It shares architectural similarities with other members like the 7035 but differs in density and pinout. The series is known for robust semaphore-based arbitration. It serves as a legacy solution for embedded systems requiring fast, independent memory access paths.

Memory IC Replacement Considerations

Check for direct pin-compatible replacements within the same family. Verify if newer generations offer improved power consumption. Ensure substitute parts maintain the 18-bit data width. Confirm package dimensions match the original 100-pin TQFP form factor.
