7005S25GB

Overview

The Renesas Electronics Corporation 7005S25GB is a high-speed 8K x 8 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, with an access time of 25 ns and a 64 kbit density. The device operates on a single 5V supply within a 4.5V to 5.5V range, utilizing a parallel interface. It is housed in a 68-pin PGA package and supports asynchronous operation from either port.

Feature Summary

• True dual-ported memory architecture enabling simultaneous independent access by two ports
• On-chip hardware support for semaphore signaling and interrupt flags between ports
• Automatic power-down feature controlled by chip enable for low standby power mode
• TTL-compatible inputs and outputs with battery backup capability for data retention

Applications

• Standalone 64K-bit dual-port memory systems
• Master/Slave dual-port RAM configurations for 16-bit or wider word systems
• High-speed data buffering applications requiring concurrent port access

Procurement Notes

Verify component authenticity through authorized channels as this part may be discontinued. Confirm package integrity and moisture sensitivity level handling procedures prior to assembly. Cross-reference datasheet specifications against current design requirements to ensure compatibility with system voltage and timing constraints.

Selection Notes

Select this component when simultaneous independent read/write operations are required without external arbitration logic. The 25 ns access speed suits moderate-to-high frequency applications. Ensure the 68-pin PGA footprint fits the target PCB layout and that the industrial temperature range meets environmental operating conditions.

Part Context

This device belongs to the 7005 series of dual-port SRAMs, offering flexible configuration options for various bus widths. It provides hardware-based port arbitration, simplifying system design compared to software-managed shared memory solutions. The series supports both standalone and cascaded modes for expanded memory architectures.
