ACU7505 chip MP3 player memory circuit - schematic

chip work when large data storage capacity requirements, set up in memory of the two of maple. Both constitute the memory circuit is completely consistent, are made K9KIG28UOM chip and peripheral circuits, the memory of the main pin functions shown in the figure. Since the case of a semiconductor memory device, also need DC power supply (vcc) Thus when working.
