GS8673EQ18BGK-675I

Memory IC Overview

The GS8673EQ18BGK-675I is a 72 Mbit synchronous static random-access memory (SRAM) manufactured by GSI Technology Inc. It features a 4M x 18 organization with a parallel interface and supports a maximum clock frequency of 675 MHz. The device operates within a supply voltage range of 1.25 V to 1.4 V, with a maximum power current of 1.77 A. It utilizes QDR-III storage technology and is housed in a 260-pin BGA package suitable for surface mount installation. The component functions reliably across an operating temperature range from -40°C to +100°C.

Memory IC Feature Summary

• Data center switching systems

Memory IC Procurement Notes

Verify the specific suffix 'I' indicates industrial temperature rating compliance before ordering. Confirm the 260-BGA pinout matches your PCB footprint design. Ensure voltage regulators support the 1.25V to 1.4V operational window. Check for moisture sensitivity level requirements during assembly. Validate that the 675 MHz timing parameters align with your system clock constraints.

Memory IC Selection Notes

Select this model when a 4M x 18 word width is required for wide data paths. Choose over narrower variants if system bus width dictates 18-bit alignment. Consider the 675 MHz speed grade for latency-sensitive applications. Evaluate the BGA-260 package for space-constrained board layouts. Compare against DDR-III alternatives if quad-port throughput is not strictly necessary.

Memory IC Part Context

This component belongs to the SigmaQuad-IIIe family of SRAMs designed for high-performance embedded systems. It complements other GS8673 series parts like the ED36BGK variant which offers a 2M x 36 organization. The family shares common packaging and thermal characteristics while differing in data width and access speed grades.

Memory IC Replacement Considerations

Direct substitutes include GS8673EQ18BGK-500I for lower speed requirements or GS8673ED36BGK-675I for wider data interfaces. Verify pin compatibility and electrical specifications before swapping. No generic cross-model replacements are confirmed without specific datasheet validation.
