Does not output the internal system clock. • Selectable source clock: external clock input and crystal resonator [External clock] On-chip PLL to provide higher operation clock (60 MHz max.) than the external clock. Variable multiple rates (1, 2, 3, 4, 8) by mask option. [Crystal resonator] Oscillation frequency corresponds directly to the system clock frequency (Sure to specify the mask option frequency multiple as "1"). • ON-CHIP PERIPHERAL • I/O port: 4 bits • Serial I/O (16 bits): 2 channels • Host I/O (8 bits): 1 channel • CMOS • +3 V single power supply ORDERING INFORMATION Part Number Package µPD77018AGC-×××-9EU 100-pin plastic TQFP (FINE PITCH) (14 × 14 mm) µPD77019GC-×××-9EU 100-pin plastic TQFP (FINE PITCH) (14 × 14 mm) Remark ××× indicates a code suffix. |
