Additional Details

The W942516CH-75 operates at a voltage of 1.8V. The '-75' indicates a speed grade corresponding to DDR2-667 specifications. Precise timing specifications (CAS latency, tRCD, tRP, tRAS) must be obtained from the official Winbond datasheet for accurate configuration and operation. The device is available in FBGA packaging. The integration of on-chip DLL (Delay-Locked Loop) facilitates accurate alignment of data (DQ) and data strobe (DQS) signals with the clock signals, mitigating timing skew and enhancing signal integrity at high operating speeds. This makes the W942516CH-75 a suitable choice for applications that necessitate high-speed and reliable memory performance. Auto refresh function allows for low power operations while retaining data. The data mask feature allows users to write to specific bytes without disturbing other data.
