LC66306A 데이터시트(HTML) 7 Page - Sanyo Semicon Device |
7 / 26 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. 5486-7/26 LC66E2316 Pin I/O Overview Output driver type Options State after a Standby mode reset operation PC2/CE PC3/DASEC PD0/INV2I PD1/INV2O PD2/INV3I PD3/INV3O PE0 PE1 OSC1 OSC2 RES/VPP/ OE TEST/ EPMOD VDD VSS I/O ports PC2 to PC3 • Output in 2-bit or 1-bit units • PC3 is also used as the control CE and DASEC pin in EPROM mode. Dedicated input ports PD0 to PD3 Dedicated inverter circuits (option) Dedicated input ports 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. • This pin is also used as the VPP/OE pin in EPROM mode. CPU test pin This pin must be connected to VSS during normal operation. Setting this pin to +12 V switches the LC66E2316 to EPROM mode. Power supply pins I I I I O I I • Pch: CMOS type • Nch: Intermediate sink current type • When the inverter circuit option is selected. • Pch: CMOS type • Nch: Intermediate sink current type CMOS or Nch OD output Inverter circuits Ceramic oscillator or external clock selection H Normal input Inverter I/O goes to the output off state. Option selection Hold mode: Port output off Hold mode: Inverter Output off Halt mode: Inverter output continues Hold mode: input disabled Hold mode: oscillator stops Halt mode: inputs accepted Halt mode: oscillator continues Halt mode: Port output retained |
