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

²S2², 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 ²S1² and return to the count-up/down

mode by releasing ²S1².

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

before set time and 8 alarm sounds at 5 minutes

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.
