Additional Details

The W9412G2IB-5 operates at a voltage of 1.8V. The speed grade '-5' indicates the device is suitable for DDR2-1066 speeds. It is crucial to refer to the official Winbond datasheet for the complete and accurate timing parameters (CAS latency, tRCD, tRP, tRAS) specific to this part number. The device is usually available in a FBGA package. The integration of on-chip DLL (Delay-Locked Loop) ensures precise alignment of data (DQ) and data strobe (DQS) signals with the clock signals, reducing timing skew and improving signal integrity at high operating speeds. This makes the W9412G2IB-5 an excellent choice for applications where high-speed, reliable memory performance is critical.
