General Description
The LS6032 is a 4 digit timer with a real time clock. It is three keys operation : KH, KL and KST. It
is very universal such that the user can tailor to the specific application as needed by bonding option.
There are 8 bonding options :
1.
2.
3.
4.
5.
6.
7.
8.
BUP : enable/disable count up function.
BDN : enable/disable count down function.
BMMSS : Hour/Minute or Minute/Second timer.
B99 : Maximum is 99Hour/Minute or 19Hour/Minute.
BNCLOCK : enable/disable clock function.
BSET : enable/disable timer setting in PAUSE mode.
BNREP : enable/disable count down repeat function.
BOFF : enable/disable LCD off function.

Functional Description
Power up
At power up, the LS6032 turns on all LCD for 1 second.
If BNCLOCK == VDD, the LS6032 display timer.
If BNCLOCK == GND, the LS6032 display clock “am 1:00”.
Clock Mode
In Clock Mode, press KH enters clock setting mode.
The setting sequence is : Clock Mode Set Clock Hour Set Clock Minute Clock Mode.
Press KL to set the corresponding value.
Press KST enters Timer Mode.
Timer Mode Operation
The operation of the LS6032 depends on the 8 bonding option .
(Note : All bonding option input has a pull high resistor, therefore, floating == VDD).

Description
Count up enable.
Press KST will count up if the timer value is 0:00.
Count up disable
Press KST will have no function is the timer value is 0:00.
Count down enable.
Press KL, KH sets the timer value for count down.
Count down disable
Press KL,. KH has no function for setting (no count down).
Minute Second mode.
Press KL sets second value, KH sets minute value.
Hour Minute mode.
Press KL sets minute value, KH sets hour value.
Maximum range for hour setting is 99Hours.
Maximum range for hour setting is 19Hours.
No Clock
Enable clock. In timer mode, press KL,KH, KST simultaneously enters clock
mode.
Enable setting in PAUSE mode.
While the timer is counting, press KST enters PAUSE mode.
No setting in PAUSE mode.
No repeat function.
Repeat function enabled.
The timer will restart from the setting value by the end of count automatically.
The alarm will last for 1 minute
If clock is selected (BNCLODK==GND), the timer return to clock mode after 1
minute of idle state.
If clock is not selected (BNCLOCK==VDD), the timer will be off.
If clock is selected (BNCLODK==GND), the timer return to clock mode after 1
minute of idle state.
If clock is not selected (BNCLOCK==VDD), the timer will be permanently on.
