General Description
The LSI6015 is a rotating clock which the clock can be placed in four direction (up/down/left/right)
and the LCD display the correct time/date information. It has a 3 key operation : SET, MODE, ADJ. It
has 4 direction input to detect the display mode. The LSI6015 can be selected to operate in 12 hour/24
hour format depending on bonding option.
The LSI6015 directly drive a 1/2 duty 1/3 bias LCD. It has a very low current consumption and is
suitable for timer application.

Functional Description
Power up
At power up, the LSI6015 turns on all LCD and starts the clock from 1:00am (Time Mode).
Key operation
The LSI6015 has three key operation MODE, SET, ADJ.
At Time Mode, press MODE key display the current date (Date Mode), press MODE again goes back
to Time Mode and display the current time.
SETTING TIME
At Time Mode, press SET over 2 seconds enter Hour Setting Mode.
At Hour Setting Mode, press ADJ to adjust the hour, press MODE key goes to Minute Setting Mode.
At Minute Setting Mode, press ADJ to adjust the minute, press MODE key goes back to Time Mode.
SETTING DATE
At Date Mode, press SET over 2 seconds enter Month Setting Mode.
At Month Setting Mode, press ADJ to adjust the current month, press MODE key goes to Date Setting
Mode.
At Date Setting Mode, press ADJ to adjust the current date, press MODE key goes back to Date Mode.
12HOUR/24HOUR OPTION
When 12/24 is connected to VDD, the LSI6015 display the clock in 12 hour format.
When 12/24 is connected to GND, the LSI6015 display the clock in 24 hour format.
ROTATE THE CLOCK
When DOWN/UP/LEFT/RIGHT is connected to GND, the LSI6015 display the clock/date in
