Description
Power Back-up pin(+).
. At Li Mode, connect a 0.1u capacitor to GND.
LCD supply voltage and positive supply pins.
. In Ag power mode, connect positive power to VDD1.
. In Li or ExtV power mode, connect positive power to VDD2.
Input pin for external reset request signal, built-in internal pull-down resistor.
. Reset cycle time can be defined as “PH15/2” or “PH12/2” by mask option.
. Reset Type can be defined as “Level reset” or “Pulse reset” by mask option.
Input pin for external interrupt request signal.
. Falling edge or rising edge triggered is defined by mask option.
. Internal pull-down or pull-up resistor is defined by mask option.
Test signal input pin.
Switching pins for supply the LCD driving voltage to the VDD1,2,3 pins.
. Connect the CUP1 and CUP2 pins with non-polarized electrolytic capacitor when chip
operated in 1/2 or 1/3 bias mode.
. In no BIAS mode application, leave these pins opened
Time base counter frequency (clock specified. LCD alternating frequency. Alarm signal
frequency) or system clock oscillation.
. 32KHz Crystal oscillator.
. In FAST ONLY mode option, connect an external resistor could compose a RC
oscillator.
Output pins for driving the common pins of the LCD or LED panel.
Output pins for driving the LCD or LED panel segment.
