The device operates within a voltage range of 1.7 V to 1.9 V, with a maximum power supply current of 490 mA. It utilizes a parallel interface and is housed in a BGA-165 package suitable for surface mount technology. The component is rated for an industrial operating temperature range from -40°C to +85°C.

Memory IC Feature Summary

• Supports high-speed data transfer via a parallel DDR interface architecture
• Operates on low voltage power supplies ranging from 1.7 V to 1.9 V
• Designed for industrial environmental conditions with extended temperature tolerance

Memory IC Applications

• High-performance networking equipment requiring fast buffer memory
• Telecommunications infrastructure systems
• Industrial control systems demanding reliable synchronous memory

Memory IC Procurement Notes

Verify the exact part number suffix against official manufacturer documentation, as variations such as -300 or -167 indicate different speed grades. Confirm availability status directly with authorized distributors, as some listings may indicate restricted supply or end-of-life notifications. Ensure the specific revision matches the design requirements for voltage and timing parameters.

Memory IC Selection Notes

Select this component when a 18 Mbit capacity with a 18-bit data width is required at 400 MHz speeds. Compare against other speed grades like -300 if lower performance is acceptable for cost reduction. Ensure the PCB layout supports the BGA-165 footprint and that the system power supply can handle the peak current draw specified in the datasheet.

Memory IC Part Context

This part belongs to the SigmaQuad-II+ family of synchronous static RAMs from GSI Technology. These devices are engineered to provide high bandwidth and low latency for complex digital signal processing and buffering applications. The series typically offers various density and speed options within the same package form factor to simplify design-in processes across different product generations.

Memory IC Replacement Considerations

Check for compatible parts within the same GS8182D19BGD series, such as the GS8182D19BGD-300I, which shares the same pinout and organization but operates at a lower 300 MHz frequency. Verify electrical compatibility before substitution.
