6 Dot Animation 4 Digit Alarm Clock With Calendar

Features: (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 pr ess 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 : /square6 One by one[off, 1, 2, 3, 4, 5, 6, off, 1, 2, 3, ….] . /square6 Accumulated[off, 1, 1+2, 1+2+3, 1+2+3+4, …. 1+2+3+4 +5+6, off, 1, ..]. /square6 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 i s based on a 32768Hz quartz crystal controlled oscillator. An oscillator capacitor is b uild in the chip. An external 32768Hz quartz crystal is required to complete the oscillat or circuit. The operation of the basic timekeeping functions is controlled via two keys. W hen 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 capaci tors. Only one 1.5V battery is required to power the entire circuit.

(a) After the power on, it switch into clock state and shows “12:00”(12 hour format). The default value “1 Jan 12:00:00”. (b) It shows 12 hour format and four group of “Hour/minute”, “Alarm time”, “Month/date”, and “second”. In clock state, “Hr : Min” is shown with colon flashing 0.5 sec on and 0.5 sec off. Press “M” key to indicate the “Alarm time” (if no key is pressed for 5 seconds, it will auto return to clock state “Hr : Min”), press “M” key again to indicate the “Month/date” (if no key is pressed for 5 seconds, it will auto return to clock state “Hr : Min”). Press again to show the “second”. It can be clear by pressing “S” key. It will stay in second indication until return to clock state by pressing “M” key (the colon always on and not flash in second state, it only flash in clock state “Hr : Min”). (c) In normal state, press “S” key into the clock setting state. The first setting is alarm option (alarm on/off or chime on/off), it can be change by pressing “M” key. Press “S” key to alarm hour setting, it can be set cycling from “12: A”(12 hour format) to “11: A”(12 hour format), “12: P”(12 hour format) to “11: P”(12 hour format) by pressing “M” key. Hold(2 sec) the “M” key will have auto advance. Press “S” key to alarm minute setting, it can be set from 0 to 59 by pressing “M” key. Hold (2 sec) the “M” key will have auto advance. Press “S” key to return normal mode (with alarm setting) or month setting (without alarm setting), it can be set from 1 to 12 by pressing “M” key. Hold (2 sec) the

“M” key will have auto advance. Press “S” key to date setting, it can be set from 1 to 28/30/31(depend the month) by pressing “M” key. Hold (2sec) the “M” key will have auto advance. Press “S” key to hour setting, it can be set cycling from “12: A”(12 hour format) to “11: A”(12 hour format), “12: P”(12 hour format) to “11: P”(12 hour format) by pressing “M” key. Hold (2 sec) the “M” key will have auto advance. Press “S” key to minute setting, it can be set from “:00” to “:59” by pressing “M” key. Hold (2 sec) the “M” key will have auto advance. Press “S” key to return normal mode (without minute setting) or hold mode(with minute setting). In the hold mode, press “M” key only to retu rn normal mode.
