LC66358A Fiches technique(HTML) 6 Page - Sanyo Semicon Device |
6 / 21 page Continued from preceding page. Note: Pull-up MOS type: The output circuit includes a MOS transistor that pulls the pin up to VDD. CMOS output: Complementary output. OD output: Open-drain output. No. 5484-6/21 LC66354C, 66356C, 66358C Pin I/O Overview Output driver type Options State after a reset P60/SI0 P61/SO1 P62/SCK1 P63/PIN1 PC2/VREF0 PC3/VREF1 PD0/CMP0 PD1/CMP1 PD2/CMP2 PD3/CMP3 PE0/TRA PE1/TRB OSC1 OSC2 RES TEST VDD VSS I/O ports P60 to P63 • Input or output in 4-bit or 1-bit units • P60 is also used as the serial input SI1 pin. • P61 is also used as the serial output SO1 pin. • P62 is also used as the serial clock SCK1 pin. • P63 is also used for the event count input to timer 1. I/O ports PC2 and PC3 • Input or output in 2-bit or 1-bit units • PC2 is also used as the VREF0 comparator comparison voltage pin. • PC3 is also used as the VREF1 comparator comparison voltage pin. Dedicated input ports PD0 to PD3 • These pins can be switched in software to function as comparator inputs. • The comparison voltage for PD0 is provided by VREF0. • The comparison voltage for PD1 to PD3 is provided by VREF1. • Pins PD0 and PD1 can be set to the comparator function individually, but pins PD2 and PD3 are set together. Dedicated input ports These pins can be switched in software to function as three-value inputs. System clock oscillator connections When an external clock is used, leave OSC2 open and connect the clock signal to OSC1. System reset input When the P33/HOLD pin is at the high level, a low level input to the RES pin will initialize the CPU. CPU test pin This pin must be connected to VSS during normal operation. Power supply pins I/O I/O I I I O I I • Pch: CMOS type • Nch: Intermediate sink current type • Nch: +15-V handling when OD option selected • Pch: CMOS type • Nch: Intermediate sink current type CMOS or Nch OD output CMOS or Nch OD output Use of either a ceramic oscillator or an external clock can be selected.
