7006S35J

Overview

The Renesas Electronics Corporation 7006S35J is a dual-port asynchronous static random access memory integrated circuit. It provides a storage capacity of 128Kb, organized as 16K words by 8 bits. The device features a parallel interface with a maximum access time of 35 ns. It operates on a single 4.5V to 5.5V power supply and supports surface mount installation in a 68-pin PLCC package measuring 24.21x24.21 mm. The component functions within an ambient temperature range of 0°C to 70°C.

Feature Summary

• Supports simultaneous independent reads from both ports for the same memory location
• Includes on-chip hardware logic for semaphore signaling between ports
• Features automatic power-down mode controlled by chip enable signals

Applications

• Stand-alone 128K-bit dual-port RAM systems
• Master/Slave dual-port RAM configurations for 16-bit or wider word systems
• Battery backup operation requiring data retention

Procurement Notes

Verify current availability status as this component may be subject to discontinuation notices. Confirm RoHS compliance requirements against specific project standards, as older variants may not meet current environmental directives. Ensure the 68-PLCC footprint matches the target PCB design constraints before finalizing procurement decisions.

Selection Notes

Select this component when true dual-port functionality with simultaneous read access is required. It is suitable for applications needing hardware-based port arbitration and semaphore support. Consider the 35 ns access speed and 5V TTL-compatible interface for compatibility with standard digital logic families.

Part Context
