W631GG6MB15I

Memory IC Overview

The W631GG6MB15I is a 1 Gbit DDR3 SDRAM organized as 8,388,608 words by 8 banks by 16 bits. It supports a maximum operating frequency of 667 MHz (DDR3-1333) with timing parameters of 9-9-9. The device operates at a supply voltage of 1.5V ± 0.075V and features an SSTL_15 interface. It is packaged in a 96-ball VFBGA measuring 7.5 x 13 mm². The industrial temperature grade (-15I) guarantees operation within a case temperature range of -40°C to 95°C.

Memory IC Feature Summary

• Supports double data rate architecture with two data transfers per clock cycle for high-speed performance.
• Features eight internal banks allowing concurrent operations to improve system efficiency.
• Includes programmable on-die termination (ODT) and dynamic ODT modes to enhance signal integrity.
• Provides ZQ calibration capabilities for output driver and ODT using external reference resistors.

Memory IC Applications

• Industrial control systems requiring stable memory performance across wide temperature ranges.
• Embedded computing platforms utilizing DDR3-1333 specifications.
• High-density memory subsystems needing 16-bit data bus interfaces.

Memory IC Procurement Notes

Verify the specific speed grade suffix '15I' corresponds to the required 667 MHz frequency and industrial temperature range during procurement. Confirm package dimensions match the 96-ball VFBGA specification. Check RoHS compliance status and moisture sensitivity levels before assembly. Ensure ordering documentation aligns with the manufacturer's current revision A02 datasheet requirements.

Memory IC Selection Notes

Select this component when a 16-bit data width and 1 Gbit capacity are required for DDR3 applications. The -15I designation ensures compatibility with industrial environments up to 95°C. Consider the 667 MHz limit if higher bandwidth is needed, as other speed grades exist within the same family. Verify power supply constraints match the 1.5V requirement for proper integration.

Memory IC Part Context

This part belongs to the W631GG6MB series of DDR3 SDRAMs manufactured by Winbond Electronics. The series includes various speed grades ranging from DDR3-2133 to DDR3-1333. The '15I' suffix specifically denotes the DDR3-1333 speed bin with industrial temperature support. The device utilizes a standard 96-ball VFBGA package suitable for surface mount technology.

Memory IC Replacement Considerations

Direct substitutes include other W631GG6MB variants with different speed grades such as W631GG6MB12I or W631GG6MB11I, provided the lower frequencies are acceptable. Cross-manufacturer replacements require verification of pinout compatibility and electrical characteristics against the original datasheet specifications.
