• Provides 72 Mbit density through a 2M x 36 bit organization structure
• Operates on dual voltage supplies of 1.8 V or 1.5 V
• Designed for industrial environments with extended temperature tolerance

Memory IC Applications

• High-performance networking equipment requiring fast packet buffering
• Telecommunications infrastructure systems
• Industrial control applications demanding reliable memory access
• Test and measurement instruments

Memory IC Procurement Notes

Verify the specific suffix 'I' indicates the industrial temperature grade (-40°C to +85°C) against the manufacturer datasheet. Confirm the BGA-165 pinout matches the target PCB footprint design. Ensure supply chain sources provide original manufacturer documentation to validate RoHS compliance status. Cross-reference the 357 MHz speed bin requirement with system timing constraints before finalizing procurement orders.

Memory IC Selection Notes

Select this component when a 36-bit wide data path is required for high-throughput applications. The 357 MHz speed grade offers significant bandwidth advantages over lower-frequency variants in the same series. Consider the 1.205 A maximum current draw for adequate power delivery network design. The BGA-165 package requires specialized surface mount assembly processes compared to leaded packages.

Memory IC Part Context

This part belongs to the SigmaQuad-II+ family of QDR SRAM devices from GSI Technology. It shares architectural similarities with other members like the GS8662QT37BGD-200I but differs in maximum clock frequency and associated power characteristics. The series is designed for synchronous operation, distinguishing it from asynchronous SRAM options. It serves as a critical memory solution for latency-sensitive digital signal processing tasks.

Memory IC Replacement Considerations

Direct substitutes include the GS8662QT37BGD-333T and GS8662TT37BGD-333I, which offer similar 36-bit widths but operate at lower clock frequencies of 333 MHz. Verify that the reduced speed grades meet the system timing requirements if substituting these parts.
