General Description
The HT1330 is a CMOS fabricated LSI chip de-
signed to drive a standard three and 1/2 digit
biplexed LCD for a count-up/down timer in
watch applications. The watch and timer are
based on a 32768Hz quartz crystal oscillator.
The maximum count-down time is 20 hours
with an accuracy of 1 second. The maximum
count-up period is 20 hours, but the LCD will
normally display a maximum period of 19 min-
utes and 59 seconds. If the user presses switch
S2 , the total count-up time in hours and min-
utes will be displayed. In the count-up/down
mode, the real time can be seen by pressing
switch S1 and return to the count-up/down
mode by releasing S1 .
Once the count-down is finished, the timer can
either automatically recycle the preset time or
manually reset the desired time depending on
the selected bonding-pad option. The forecast
alarm generates 4 alarm sounds at 10 minutes
beforesettimeand8alarmsoundsat5minutes
before set time. The HT1330 can be used as a
parking timer, an alarm timer, a pill box timer,
a kitchen timer, a sports timer, etc.
