7005S17G

Overview

The Renesas Electronics Corporation 7005S17G is a high-speed, asynchronous dual-port static random access memory with a storage capacity of 64 kbit. The device features an 8 k x 8 organization and supports parallel interface communication. It operates within a supply voltage range of 4.5 V to 5.5 V, with a maximum power consumption of 310 mA. The component provides a typical access time of 17 ns and functions reliably across an industrial temperature range from 0°C to +70°C. It is housed in a 68-pin PGA package designed for through-hole mounting.

Feature Summary

• True dual-ported memory architecture enabling simultaneous independent reads and writes from two distinct ports without conflict.
• Integrated on-chip hardware support for semaphore signaling and port arbitration logic to manage data integrity between master and slave operations.
• Automatic power-down feature controlled by chip enable signals, allowing the internal circuitry to enter a low standby power mode when inactive.

Applications

• Stand-alone 64K-bit dual-port RAM systems
• Master/Slave dual-port configurations for 16-bit or wider word systems
• Industrial control applications requiring asynchronous data buffering

Procurement Notes

Verify current availability status as this component may be subject to discontinuation notices. Confirm that the 68-pin PGA package aligns with existing PCB footprints and manufacturing processes. Ensure compliance with RoHS directives if required for specific regional regulations. Validate moisture sensitivity level handling procedures during assembly to prevent damage.

Selection Notes

Select this part when simultaneous independent access to shared memory is required without external arbitration logic. The 17 ns access speed suits moderate-speed asynchronous interfaces. Consider the PGA package constraints for through-hole assembly versus surface-mount alternatives like TQFP or PLCC variants within the same series.

Part Context

The 7005S17G belongs to the Renesas 7005 series of dual-port SRAMs, originally developed by IDT before acquisition. This series is characterized by its TTL-compatible 5V operation and robust hardware-based synchronization features. It serves as a legacy solution for applications needing simple, reliable dual-port memory without complex software management.

Replacement Considerations

IDT7005S17G is a confirmed equivalent part number representing the same functional specifications and pinout compatibility.
