LS3262 single chip CMOS timer circuit
■The LS3262 is a single chip CMOS timer circuit with calendar. It is designed to drive a LCD(4 digits). The timer circuit is based on a 32768Hz quartz crystal controlled oscillator. An oscillator capacitor is build in the chip. An external 32768Hz quartz crystal is required to complete the oscillator circuit. The operation of the basic timekeeping functions is controlled via two keys. When power up reset, the clock will be reset to 1.1 12:00 and 00 seconds(12 hour format). The circuit has a built-in voltage doubler (to drive the LCD ) which needs two external capacitors. Only one 1.5V battery is required to power the entire circuit. It has a trigger output to drive external I.C. Direct drive buzzer output.
●Features:
■Single 1.5V operating voltage.
▲Directly driving 2x14 segment LCD.
▲4 display functions: Clock(12 hour format), daily alarm, date and second.
▲External trigger function in daily alarm output.
▲Daily Alarm - It generates a sound (4KHz x 8Hz x 1Hz) with external trigger function for 60 seconds. Pressed any key to stop it. Chime Function - Every hour on the hour, beep sound (4KHz x 4Hz x 1Hz) for 1 second.
▲32768 Hz quartz crystal provide the time base, and machine cycle = 4KHz.
▲Power on reset: When the power up, all LCD segments and the alarm sound are turned on for one second.
▲Programmable reset: When “ M ” key and “ S ” key press together, all LCD segments and it generates a sound(4KHz x 8Hz x 1Hz)with external trigger function. It will be stop and return to normal clock mode until release all keys..
▲Low power dissipation.
▲Keys: “ M --- Mode (mode and adjust), “ S --- setting.
