W9725G8KB25I TR

Memory IC Overview

The W9725G8KB25I TR is a 256 Mbit DDR2 SDRAM manufactured by Winbond Electronics. It features an organization of 32 Meg x 8 bits and operates within a supply voltage range of 1.7 V to 1.9 V. The device supports industrial temperature operation from -40°C to +85°C. It is housed in a 60-pin WBGA package with surface mount installation. The component utilizes a reel packaging format for automated assembly processes.

Memory IC Feature Summary

• Supports double data rate synchronous dynamic random access memory architecture
• Includes self-refresh mode for low-power standby operations
• Utilizes differential clock inputs for improved signal integrity

Memory IC Applications

• Embedded systems requiring moderate density memory
• Industrial control modules
• Consumer electronic devices

Memory IC Procurement Notes

Verify current manufacturing status directly with the manufacturer, as lifecycle information may be incomplete. Confirm moisture sensitivity level handling requirements prior to PCB assembly. Ensure the specific reel quantity matches production needs. Cross-reference the exact suffix to confirm temperature grade and package variant compatibility with existing designs.

Memory IC Selection Notes

Select this component when a 256 Mbit capacity with an 8-bit bus width is required. The industrial temperature rating makes it suitable for environments exceeding commercial limits. The 60-pin WBGA package offers a compact footprint for space-constrained layouts. Verify system timing constraints align with DDR2-800 specifications.

Memory IC Part Context

This part belongs to the W9725G8KB series of DDR2 SDRAMs. It shares architectural similarities with other members of the family but differs in organization and package type. The series is designed for general-purpose memory applications where power efficiency and moderate speed are prioritized over high-bandwidth performance.

Memory IC Replacement Considerations

Check for direct pin-to-pin replacements with identical electrical characteristics. Verify that any substitute maintains the same 32M x 8 organization and 60-pin WBGA package. Ensure the replacement supports the required industrial temperature range and voltage specifications.
