6 Dot Animation 4 Digit Alarm Clock With Calendar
LS 3263
(a) Single 1.5V operating voltage.
(b) Directly driving 2x14 segment LCD.
(c) 3 display functions: Clock(12 hour format), date and second.
(d) 32768 Hz quartz crystal provide the time base, and machine cycle = 4KHz.
(e) Power on reset: When the power up, all LCD segments and the alarm sound
are turned on for one second.
(f) 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..
(g) Low power dissipation.
(h) Key tone : It will generate a sound signal (tone) when only one key is pressed.
(i) Bonding option to select total numbers of dots(3, 4, 5 and 6 dots)
(j) Animation of dots with 3 bonding option :
One by one[off, 1, 2, 3, 4, 5, 6, off, 1, 2, 3, ….].
Accumulated[off, 1, 1+2, 1+2+3, 1+2+3+4, …. 1+2+3+4+5+6, off, 1, ..].
Special pattern[off, 1+2, 2+3, 3+4, 4+5, 5+6, off, 1+2, …]
(k) Keys: “ M ” --- Mode (mode and adjust), “ S ” --- setting.
General Description
The LS3263 is a single chip CMOS timer circuit with new animation watch I.C. It is
designed to direct drive a LCD. 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.
