Additional Details:

The V58C2256804SCI-5I operates at a voltage of 2.5V. It is packaged in a standard TSOP package. The data mask (DM) input allows for selective writing of data to the memory array. The auto precharge feature simplifies memory management by automatically precharging the memory cells after a burst operation. The self-refresh mode allows the memory to retain data while consuming minimal power. The part is also compliant with industry standards for DDR SDRAM, ensuring compatibility with a wide range of systems.
