7005S17J

Overview

The Renesas 7005S17J is a high-speed, asynchronous dual-port static random-access memory (SRAM) with a density of 64 kilobits. It features an 8k x 8 organization and supports simultaneous independent access from two ports. The device operates on a single 5V power supply within a range of 4.5V to 5.5V. It provides a maximum access time of 17 nanoseconds and functions within a commercial temperature range of 0°C to 70°C. The component is housed in a 68-pin Plastic Leaded Chip Carrier (PLCC) package.

Feature Summary

True dual-ported memory architecture enabling simultaneous reads of the same location
On-chip hardware support for semaphore signaling between ports
Automatic power-down feature controlled by chip enable signals
TTL-compatible inputs and outputs

Applications

Stand-alone 64K-bit dual-port RAM systems
Master/Slave dual-port configurations for 16-bit or wider word systems
Battery-backed data retention applications

Procurement Notes

Verify the specific suffix 'J' against official Renesas documentation to confirm the PLCC-68 package type and commercial temperature rating. Confirm current production status as this series may be subject to discontinuation notices. Ensure compatibility with existing PCB footprints for 68-pin PLCC components during procurement planning.

Selection Notes

Select this component when simultaneous independent port access is required without external arbitration logic. It is suitable for systems needing fast parallel interface speeds with 17ns latency. Consider the 68-pin PLCC package constraints for board layout. Verify that the 5V TTL I/O levels match the system voltage requirements.

Part Context

This part belongs to the Renesas 7005 series of dual-port SRAMs. The series offers various speed grades and package options including PGA and TQFP. The 7005S17J specifically denotes the 17ns speed grade in a PLCC package. This family is designed for applications requiring high-speed data sharing between processors.
