Description
Power source VDD-VSS: Supply voltage internal logic VDD-VEE: Supply voltage display tube driving circuit logic Microcontroller Input display data shift register Input from (positive logic). Shift clock shift register. Data shifted falling edge SCLK. Latch clock input display data. When this level, data latched pass through latch circuit. When level, data when level latched. Internal logic reset input upon power-on. During reset, 18-bit internal latch, duty cycle register, digital register, register, write/read address register reset, outputs SEGA SEGP(*a), (*b), LED1 LED5 off. Connecting external capacitor allows poweron reset. Input oscillation circuit When external resistor capacitor connected, oscillation circuit formed. C=100pF, R=47kW fOSC=235kHz±20%
