Additional Details

The W9425G6DH-4 typically operates at a voltage of 1.8V. The '-4' denotes a specific speed grade usually related to DDR2-800 operation. Specific timing specifications (CAS latency, tRCD, tRP, tRAS) should always be verified using the official Winbond datasheet for the specific part number. This DDR2 SDRAM usually comes in a FBGA (Fine-pitch Ball Grid Array) package for surface mount assembly. The device incorporates an on-chip DLL (Delay-Locked Loop) that meticulously aligns the data (DQ) and data strobe (DQS) signals with clock transitions. This precise alignment effectively minimizes timing skew, subsequently optimizing signal integrity at elevated operating speeds. This makes the W9425G6DH-4 a good choice for implementations where high-speed, dependable memory performance is paramount.
