GS8342Q18BGD-357I

Memory IC Overview

The GS8342Q18BGD-357I is a 36 Mbit Static Random Access Memory (SRAM) manufactured by GSI Technology Inc. It features a memory organization of 2M x 18 bits and supports a maximum clock frequency of 357 MHz. The device operates on a parallel interface with power supply voltages ranging from 1.7 V to 1.9 V. It is housed in a 165-pin FBGA package designed for surface mount technology. The component supports an extended industrial operating temperature range from -40°C to +100°C.

Memory IC Feature Summary

• Integrates a built-in delay-locked loop for precise timing control
• Includes boundary scan capabilities via JTAG interface for testing
• Features a built-in write inhibit function for data protection

Memory IC Applications

• High-speed digital signal processing systems
• Network infrastructure equipment requiring large buffer memories
• Industrial control systems operating in extended temperature environments

Memory IC Procurement Notes

Verify the specific suffix 'I' confirms the extended industrial temperature range (-40°C to +100°C). Confirm the 165-pin FBGA footprint matches your PCB design constraints. Ensure voltage levels align with the 1.7V to 1.9V specification. Check for RoHS compliance documentation if required by your manufacturing standards.

Memory IC Selection Notes

Select this component when high-density 18-bit wide memory is required at speeds up to 357 MHz. The industrial temperature rating makes it suitable for harsh environments where standard commercial parts would fail. Consider the BGA package size and pin count during layout planning to ensure adequate thermal and electrical performance.

Memory IC Part Context

This part belongs to the SigmaQuad-II+ family of SRAMs, designed for high-performance applications. The GS8342 series offers various density and speed options. The Q18 variant specifically provides 18-bit data width, distinguishing it from 8-bit or 16-bit configurations within the same product line.

Memory IC Replacement Considerations

Check for other variants in the GS8342Q series with different speed grades or temperature ratings. Verify pin compatibility before substituting with similar 165-pin FBGA SRAMs from other manufacturers.
