PIN DESCRIPTION
Name VDD VDD1,2 RESET TESTA CUP1,2 COM1~4 SEG1-9 IOC3 I/O P P I O O O I/O Description Positive power supply. Connect a 0.1u capacitor to GND. LCD supply voltage, and reference power supply voltage. Both pins have to connect a 0.1uf capacitor to GND. Input pin for chip reset request signal, with internal pull-down resistor. Test signal input pin. Switching pins for supply the LCD driving voltage. Connect the CUP1 and CUP2 pins with a 0.1uf non-polarized electrolytic capacitor, Output pins for driving the common pins of the LCD panel. Output pins for driving the LCD panel segment. 1. Input / Output port C, can use software to define internal pull-low / low-level-hold Resistor and Chattering clock to reduce input bounce. 2.ROUT in Ext-R option mode , in the mode IOC function no used. 1 input pin and 2 output pins for RFC application. Output port for alarm, frequency or melody generator Negative supply voltage. RIN in Ext-R option. For testing Input pin Input pin Input pin Input pin
