lsi ls 6032 4 digit universal timer with clock version 1.2 (29.12.00) 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 cloc k. 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 optio n. there are 8 bonding options : 1. bup : enable/disable count up function. 2. bdn : enable/disable count down function. 3. bmmss : hour/minute or minute/second timer. 4. b99 : maximum is 99hour/minute or 19hour/minute. 5. bnclock : enable/disable clock function. 6. bset : enable/disable timer setting in pause mode. 7. bnrep : enable/disable count down repeat function. 8. boff : enable/disable lcd off function. lcd drawing
lsi LS6032 version 1.2 (29.12.00) 2 functional description power up at power up, the LS6032 turns on all lcd for 1 seco nd. 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 bondin g option . (note : all bonding option input has a pull high re sistor, therefore, floating == vdd). bonded description vdd count up enable. press kst will count up if the timer value is 0:00. bup gnd count up disable press kst will have no function is the timer value is 0:00. vdd count down enable. press kl, kh sets the timer value for count down. bdn gnd count down disable press kl,. kh has no function for setting (no count down). vdd minute second mode. press kl sets second value, kh sets minute value. bms gnd hour minute mode. press kl sets minute value, kh sets hour value. vdd maximum range for hour setting is 99hours. b99 gnd maximum range for hour setting is 19hours. vdd no clock bncl ock gnd enable clock. in timer mode, press kl,kh, kst simultaneously enters clock mode. vdd enable setting in pause mode. while the timer is counting, press kst enters pause mode. bset gnd no setting in pause mode. vdd no repeat function. bnre p gnd repeat function enabled. the timer will restart from the setting value by th e end of count automatically. the alarm will last for 1 minute vdd 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. boff gnd 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.
