LSI LSI-6015 Rotating Clock Features * * * * * * 4 digit LCD display (rotating) Hour:Minute or Month:Date Display Rotate in 4 direction 12/24 hour display format 3 key operation Direct drive 1/2 bias 1/3 duty LCD * Very low power consumption * 32768 Crystal oscillator * Single 1.5V operation. 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. LSI LSI-6015 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 down/up/left/down position. 2 LSI LSI-6015 Pin Assignment DESIGNATION TYPE DESCRIPTION BD [0:1] OUTPUT Buzzer output F512, VCAP VEE T1, T2 E1,E2,E3,E4 COSCO COSCI VDD GND UP/DOWN/LEFT/RIGHT 12/24 MODE/SET/ADJ C[1:3] S[1:16] OUTPUT OUTPUT INPUT INPUT OUTPUT INPUT POWER POWER INPUT(PH) INPUT(PH) INPUT(PH) OUTPUT OUTPUT Doubler output -1.5V TEST pin TEST pin 32KHz oscillator output 32KHz oscillator input +1.5V power supply Ground Input key Bonding option Input key LCD Common output LCD Segment output Note: (PH) - pull high 3 LSI LSI-6015 Absolute Maximum Ratings Supply voltage Vdd - Vss..........................0 to 5V Input voltage Vin.................................Vss to Vdd Operating temperature Top .............-10°C to 60°C Storing temperature Tst ...................-40°C to 70°C Comments Stress above those listed under absolute Maximum Ratings” may cause permanent damage to the device.
