SM5902AF
The SM5902AF operates from a 3 V supply volt-
age, but a built-in level shifter is provided for use
with external 5 V DRAM ICs. There are, therefore, 2
supply pins. VDD1 is the internal 3 V IC supply, and
VDD2 is the external DRAM interface supply.
If, however, the DRAM also operates from a 3 V
supply, VDD1 and VDD2 can be connected to the
same supply.
The SM5902AF incorporates a digital audio inter-
face output from pin DIT. Leave open circuit if not
used.
The SM5902AF supports additional function exten-
sions. Also, the UC6 pin has been removed, which
means that UC6-related commands have been
redefined.
