Additional Details

The W9864G2IH-5 SDRAM uses a double data rate (DDR) architecture to achieve high bandwidth. This means that data is transferred on both the rising and falling edges of the clock signal, effectively doubling the data transfer rate compared to single data rate (SDR) SDRAM. The device supports programmable burst lengths, allowing the user to optimize the data transfer for their specific application. The auto precharge and all bank precharge options provide flexibility in memory management, while the self refresh and power-down modes help to minimize power consumption when the device is not actively being used. It operates on a single 3.3V power supply and is available in a lead-free package. The specific temperature grade and packaging options may vary; refer to the datasheet for complete details.
