LS6032 LSI 4 Digit Universal Timer with clock Features * * * * * * 4 digit LCD display. HH:MM or MM:SS Display. Real time Clock. 3 keys operation. 8 bonding option. Direct drive 1/2 bias 1/3 duty LCD. * Very low power consumption * 32768 Crystal oscillator * Single 1.5V operation. 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. LCD Drawing Version 1.2 (29.12.00) LSI LS6032 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). BUP BONDED VDD GND BDN VDD GND BMS VDD GND B99 VDD GND BNCL VDD OCK GND BSET VDD GND BNRE VDD P GND BOFF VDD GND 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. 2 Version 1.2 (29.12.00) LSI LS6032 Mode Demonstration The maximum combinationof LS6032 is 2^8 = 256 different option selected by the 8 bonding option.
