7007S35J8

Memory IC Overview

The Renesas Electronics Corporation 7007S35J8 is a dual-port static random-access memory (SRAM) device with a storage capacity of 256 kbit, organized as 32K x 8. It features an asynchronous parallel interface with a maximum access time of 35 ns. The component operates on a single 5V power supply ranging from 4.5 V to 5.5 V, with a maximum power current of 295 mA. It is housed in a 68-PLCC surface-mount package and supports standard density random access data storage.

Memory IC Feature Summary

• Supports simultaneous independent read and write operations through two separate ports for high-throughput data handling.
• Includes on-chip hardware logic for semaphore signaling and port arbitration to manage concurrent access conflicts.
• Features automatic power-down functionality controlled by chip enable signals to reduce standby power consumption.

Memory IC Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded processing systems
• Data acquisition systems requiring low-latency memory access

Memory IC Procurement Notes

This component is officially discontinued and no longer manufactured by Renesas Electronics. Verification of availability is restricted to existing stock or surplus channels only. Buyers must confirm the authenticity of legacy inventory and check for moisture sensitivity level compliance before procurement. Replacement strategies should prioritize verified substitute part numbers rather than attempting to source new production units.

Memory IC Selection Notes

Designers should evaluate the 7007S35J8 primarily for legacy system maintenance where pin compatibility is critical. The 68-PLCC package requires specific footprint considerations during board layout. Since the device is obsolete, alternative solutions must be assessed for functional equivalence regarding voltage levels, access speeds, and physical dimensions to ensure seamless integration into existing architectures.

Memory IC Part Context

The 7007S35J8 belongs to the 7007S35 series of dual-port SRAMs produced by Renesas Electronics. This series is characterized by its ability to support master/slave configurations for wider word systems without additional discrete logic. The component utilizes advanced CMOS technology to deliver high-speed performance while maintaining TTL-compatible input levels for broad interoperability.

Memory IC Replacement Considerations

Publicly confirmed substitute part numbers are not explicitly listed in the provided documentation. Designers should consult official Renesas obsolescence notices for recommended upgrades or verify cross-reference data from authorized distributors for compatible alternatives.
