9 / 36 page Data Sheet S13918EJ3V0DS 9 µPD72012 (3/3) Pin No. Note 1 Pin Name I/O Signal Name Function 31(37) CLKSEL I CLK SELECT Pin for selecting whether to use 48 MHz oscillator or 4 MHz crystal oscillator (refer to Table 1-1). 32(38) DVDD (Buffer) -DVDD (Buffer) Connect to 3.3 V power supply. (39) DVDD - DVDD Connect to 3.3 V power supply. This pin is used together with pin No. 32 internally in the shrink DIP product. 33(40) PP1 O PORTPOWER#1 Low active open drain output pin that controls downstream port #1 power supply. Input the output of this pin to the power control element of an external circuit. If not using this pin, leave it unconnected. Note 2 34(41) PP2 O PORTPOWER#2 Low active open drain output pin that controls downstream port #2 power supply. Input the output of this pin to the power control element of an external circuit. If not using this pin, leave it unconnected. Note 2 35(42) PP3 O PORTPOWER#3 Low active open drain output pin that controls downstream port #3 power supply. Input the output of this pin to the power control element of an external circuit. If not using this pin, leave it unconnected. Note 2 36(43) PP4 O PORTPOWER#4 Low active open drain output pin that controls downstream port #4 power supply. Input the output of this pin to the power control element of an external circuit. If not using this pin, leave it unconnected. Note 2 37(44) PP5 O PORTPOWER#5 Low active open drain output pin that controls downstream port #5 power supply. Input the output of this pin to the power control element of an external circuit. If not using this pin, leave it unconnected. Note 2 38(1) DVDD -DVDD (TS0) Test pin of µPD72012 (corresponds to TS0 pin in µPD72011). Connect to 3.3 V power supply. 39(2) DGND - DGND Connect to GND. 40(3) PSSEL I Power SW Pin that selects switching between bus power and self-power (refer to Table 1-2). To make high level, pull up to 3.3 V. 41(4) PVSEL I Port Value Pin that selects switching between number (4 or 5) of downstream ports (refer to Table 1-2). To make high level, pull up to 3.3 V. 42(5) DGND - DGND (TS2) Test pin of µPD72012 (corresponds to TS2 pin in µPD72011). Connect to GND. Notes 1. QFP pin numbers are shown in ( ). 2. For details, refer to Table 1-4 of 1.2 Tables by Pin Function. |
