Table 1.3 Pin Functions Classification Symbol I/O Name Function VCCR I Power supply for internal step- down circuit Power supply pin for the internal step-down circuit. This pin must be connected to the system power supply. This LSI does not operate correctly if this pin is left open. VSSR I Ground for internal step- down circuit Ground pin for the internal step- down circuit. This pin must be connected to the system power supply (0 V). This LSI does not operate correctly if this pin is left open. VCL I Capacitor connected pin for internal step- down circuit Pin for connecting an external capacitor for the internal step-down circuit. This pin should be connected to the VSS via the external capacitor (place closer to this pin). VSS I Ground for internal step- down circuit Ground pin for the internal step- down circuit used for stabilize internal step-down power supply. This pin should be connected to the VCL via the external capacitor (place closer to this pin) PVCC I Power supply for I/O circuits Power supply pins for I/O pins. All the PVCC pins must be connected to the system power supply. This LSI does not operate correctly if there is a pin left open. Power supply PVSS I Ground for I/O circuits Ground pins for I/O pins. All the PVSS pins must be connected to the system power supply (0 V). This LSI does not operate correctly if there is a pin left open. |
