7005S15J8

Overview

The Renesas Electronics Corporation 7005S15J8 is a high-speed, asynchronous dual-port static random access memory (SRAM) with a storage capacity of 64 kbit. It features an 8k x 8 organization and operates on a single 5V power supply within a voltage range of 4.5V to 5.5V. The component provides a fast access time of 15 ns and utilizes a parallel interface for data transfer. It is housed in a 68-pin PLCC surface-mount package designed for industrial applications operating between 0°C and +70°C.

Feature Summary

• Supports simultaneous independent reads from both ports without conflict
• Includes on-chip hardware semaphore signaling for port arbitration
• Features automatic low-power standby mode controlled by chip enable signals

Applications

• Stand-alone 64K-bit dual-port memory systems
• Master/Slave dual-port configurations for 16-bit or wider word systems
• Battery-backed memory circuits requiring 2V data retention

Procurement Notes

Verify the specific suffix J8 confirms the 68-PLCC package and commercial temperature range. Confirm RoHS compliance status as documentation indicates non-compliance. Check current lifecycle status as the product may be discontinued. Ensure moisture sensitivity level 3 handling procedures are followed during assembly.

Selection Notes

Select this part when a 15 ns access speed is required for dual-port SRAM applications. Compare against other 7005 variants if different access times or package types like PGA or TQFP are needed. Verify that the 5V TTL-compatible I/O levels match the system logic requirements.

Part Context

This component belongs to the Renesas 7005 series of high-speed dual-port RAMs. The series offers various access speeds and packaging options including PLCC, PGA, and TQFP. It is designed for flexible integration into complex digital systems requiring concurrent data access.

Replacement Considerations

Check for IDT7005S15J8 as a potential equivalent identifier. Review other 7005 series members for alternative speeds or packages.
