W9751G6NB-18

Memory IC Overview

The W9751G6NB-18 is a 512 Mbit DDR2 SDRAM organized as 32M x 16 bits. It supports DDR2-1066 speeds with a CAS latency of 7 and operates at 1.8V ± 0.1V. The device uses an 84-ball VFBGA package (8x12.5 mm) and functions within a commercial temperature range of 0°C to +85°C.

Memory IC Feature Summary

• Supports double data rate architecture for high-speed data transfers up to 1066 Mbps.
• Features differential clock inputs and source-synchronous data strobes for signal integrity.
• Includes programmable additive latency, OCD impedance adjustment, and on-die termination.
• Provides auto-precharge, self-refresh, and power-down modes for efficient operation.

Memory IC Applications

• Consumer electronics requiring volatile memory storage
• Industrial control systems utilizing standard voltage interfaces
• Embedded computing platforms needing parallel DRAM connectivity

Memory IC Procurement Notes

Verify the specific speed grade suffix matches the required system timing parameters. Confirm that the operating temperature range aligns with the intended application environment. Ensure the VFBGA-84 package dimensions are compatible with the target PCB layout constraints.

Memory IC Selection Notes

Select this component when a 512 Mbit capacity with a 16-bit interface is required. Choose based on the need for DDR2-1066 performance levels. Consider the commercial temperature range suitability for the deployment location.

Memory IC Part Context

This part belongs to the Winbond W9751G6NB series of DDR2 SDRAMs. It shares architectural similarities with other speed grades in the family but is specifically optimized for the -1066 operational profile. The device utilizes standard SSTL_18 signaling protocols common to its generation.

Memory IC Replacement Considerations

W9751G6NB-25 offers identical physical characteristics but operates at lower DDR2-800 speeds. W9751G6NB-3 provides further reduced frequency capabilities while maintaining the same pinout and organization.
