W971GG8KB25I TR

Memory IC Overview

The W971GG8KB25I TR is a 1 Gbit DDR2 SDRAM organized as 16M words x 8 banks x 8 bits. It supports speeds up to DDR2-800 compliant with the 5-5-5 or 6-6-6 specification. The device operates within a voltage range of 1.7 V to 1.9 V and functions at temperatures from -40°C to +95°C. It utilizes a 60-ball WBGA package (8x12.5 mm) and is supplied in tape and reel format.

Memory IC Feature Summary

• Supports double data rate architecture for high-speed data transfers
• Includes differential clock inputs and source-synchronous data strobes
• Features on-die termination and off-chip driver impedance adjustment
• Provides auto-precharge, self-refresh, and power-down modes

Memory IC Applications

• Embedded systems requiring volatile memory storage
• Industrial control modules operating in wide temperature ranges
• Communication equipment utilizing parallel interface protocols

Memory IC Procurement Notes

Verify the specific speed grade suffix against the datasheet to ensure compliance with required timing parameters. Confirm that the industrial temperature rating (-40°C to +95°C) matches the operational environment requirements. Check for RoHS compliance status and moisture sensitivity level before procurement.

Memory IC Selection Notes

Select this component when an 8-bit data bus width is required for system integration. Ensure the design accommodates the 60-ball WBGA footprint dimensions. Verify that the controller supports the necessary initialization sequence including DLL reset and mode register programming.

Memory IC Part Context

This part belongs to the Winbond W971GG8KB family of DDR2 SDRAM devices. It shares architectural similarities with other grades like -18 and -3 but is specifically optimized for industrial temperature stability. The 'TR' suffix indicates the standard tape and reel packaging method used for automated surface mount assembly.
