7025S35GB

Memory IC Overview

The Renesas Electronics Corporation 7025S35GB is a high-speed 8K x 16 Dual-Port Static RAM designed for standalone or master/slave configurations. It features true dual-ported memory cells allowing simultaneous reads of the same location, separate upper-byte and lower-byte control for multiplexed bus compatibility, and full on-chip hardware support for semaphore signaling between ports. The device operates asynchronously from either port with TTL-compatible single 5V power supply and supports battery backup operation with 2V data retention.

Memory IC Feature Summary

• True dual-ported memory architecture enabling simultaneous independent access to shared memory locations by two distinct ports.
• Integrated interrupt flag and on-chip port arbitration logic for efficient resource management without external intervention.
• Hardware-based semaphore signaling support facilitating robust synchronization mechanisms between connected processing units.

Memory IC Applications

• High-performance computing systems requiring concurrent data access
• Multiprocessor architectures utilizing master/slave dual-port configurations
• Industrial automation controllers needing reliable synchronous communication channels

Memory IC Procurement Notes

Verify component authenticity through authorized distributors as this part may be subject to obsolescence notices. Confirm package type matches design requirements since suffixes indicate specific physical form factors. Check current lifecycle status before integration into new designs due to potential discontinuation risks associated with legacy SRAM families.

Memory IC Selection Notes

Select based on required access speed and temperature range specifications. Ensure voltage compatibility with existing system rails given the strict 4.5V to 5.5V operating window. Consider pinout differences when replacing older variants within the same family to maintain board layout integrity.

Memory IC Part Context

Part of the broader 7025 series dual-port RAM family offering various speed grades and packaging options. Designed for applications demanding high bandwidth and low latency inter-process communication. Shares common architectural features across the series while differing in electrical characteristics and physical dimensions based on specific suffix codes.

Memory IC Replacement Considerations

Consult official substitution guides for compatible alternatives such as the 7025L series which may offer improved performance metrics or updated manufacturing processes. Verify functional equivalence regarding timing parameters and signal compatibility before implementing any cross-series replacements.
