Additional Details:

The W986432DH-6 SDRAM uses a synchronous interface, meaning that data transfers are synchronized with a clock signal. This allows for higher data transfer rates compared to asynchronous memory. The device supports various operating modes, including burst mode, which allows for transferring multiple data words in a single operation. The SDRAM also features auto precharge and controlled precharge functions to simplify memory management and improve performance. The refresh rate of 8K cycles/64ms ensures data integrity. The device is available in different package options to meet various space and mounting requirements. This SDRAM is specifically designed for applications where higher performance, higher density, and lower power are required.

It operates at 3.3V and has LVTTL compatible inputs and outputs, making it easy to interface with a wide range of microprocessors and microcontrollers.
