Additional Details

The W9864G6IH-5 DDR2 SDRAM utilizes a double data rate architecture, enabling data transfer on both the rising and falling edges of the clock signal. This significantly enhances the data transfer rate compared to single data rate (SDR) SDRAM. The On-Die Termination (ODT) feature minimizes signal reflections and improves signal integrity, especially at higher frequencies. The device supports programmable burst lengths, allowing users to optimize memory access for specific application requirements. Self-refresh mode allows for low power consumption during idle periods. The '-5' likely denotes a specific speed grade or set of timing parameters. Please refer to the Winbond datasheet for detailed specifications, including voltage requirements, timing parameters, and operating temperature ranges.
