7007S35G

Memory IC Overview

The Renesas Electronics Corporation 7007S35G is a dual-port static random-access memory (SRAM) integrated circuit with a storage capacity of 256Kb, organized as 32K x 8 bits. It features asynchronous parallel interface operation with an access time and write cycle time of 35 ns. The device operates on a single 4.5V to 5.5V power supply and supports surface-mount installation in a 68-pin PLCC package. It functions within a commercial temperature range of 0°C to +70°C.

Memory IC Feature Summary

• True dual-port architecture enabling simultaneous independent read/write operations from either port without bus contention
• On-chip hardware support for semaphore signaling and interrupt flags to facilitate data synchronization between ports
• Automatic power-down mode controlled by chip enable signals to minimize standby power consumption

Memory IC Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in industrial control systems
• Data logging applications requiring fast concurrent access

Memory IC Procurement Notes

Verify component authenticity through authorized channels due to obsolete status. Confirm package integrity and moisture sensitivity level handling requirements during storage. Check for specific RoHS compliance variations across manufacturing dates. Validate pin compatibility if replacing existing designs. Ensure proper ESD protection protocols are followed during handling and assembly processes.

Memory IC Selection Notes

Select this component when dual-port functionality is required for concurrent processor access. Consider the 35 ns speed and 256Kb capacity for moderate performance needs. Evaluate the PLCC package constraints against board space limitations. Assess power supply stability requirements for the 5V logic family. Compare against newer alternatives if long-term availability is critical.

Memory IC Part Context

This part belongs to the 7007S35 series of dual-port SRAMs manufactured by Renesas Electronics. It shares architectural similarities with other members like the 7007S35J and 7007S35PF, differing primarily in package type. The series is designed for applications needing high-speed non-volatile-like behavior without the complexity of flash memory controllers.
