Cautions 1.
2.
The recommended connection of the unused pins in the PROM programming mode are
indicated in parentheses.
L
: Connect each pin to VSS via a resistor.
G
: Connect the pin to VSS.
Open : Leave the pin unconnected.
Connect NC pins to VSS for measures against noise (can leave open).
The µPD78P322K does not maintain planned reliability when used in mass-produced products. Please use only
experimentally or for evaluating functions during trial manufacture.
