FUNCTIONAL DESCRIPTIONS
MB4214 contains reference voltage circuit, oscillator, divider comparator shown Fig. Oscillator frequency arbitrary controlled external resistor capacitor input voltage. Divider consists stages divider circuit which constructed (Intergrated Injection Logic) technique. expands oscillator period 4096times. About 100hours period achieved small capacitor. Free Running Oscillation (Long period frequency) achieved when OSC/FR connected GND.
START RESISTOR
start resistor which controls zener diode current. Zener current 20mA stability zener voltage 6.2V generated.
RESET FUNCTION
Counter operation interrupted instruction reset (7pin). counter cleared when this connected GND. Power reset available connecting external capacitor CRS. Power reset time tPOR formulated: tPOR
OSCILLATOR PERIOD
kinds oscillator period selecting ways provided. Divide internal reference voltage external resistor, voltage. voltage reference voltage ratio. Oscillator period formulated: tOSC Providing voltage other power supply source. tOSC Note: Conversion value
FREE RUNNING OSCILLATION
Free running oscillation achieved when OSC/FR connected GND. outputs 4096times long fundamental oscillator frequency. After voltage applied reset released, keeps 2048times long fundamental period. When OSC/FR left open, first divider data output.
