Additional Details

The W9412G2CB-6 operates at a voltage of 1.8V. It is packaged in a FBGA (Fine-pitch Ball Grid Array) package. The specific speed grade of '-6' indicates a maximum clock frequency capability, usually associated with timings relevant to DDR2-800 operation. Detailed timings (CAS latency, tRCD, tRP, tRAS) should be confirmed via the official Winbond datasheet for this specific part number. This DDR2 SDRAM chip ensures high reliability and performance in various applications, contributing to a superior user experience in multimedia and gaming applications. The device also features on-chip DLL to align DQ and DQS transitions with clock transitions. The auto refresh function provides a convenient way to maintain data integrity without external intervention.
