光碁科技股份有限公司 Ceramate Technical Co., Ltd. CP8109 General Description : CP8109 IC is the control IC of fan without remote , built-in ON/OFF, SPEED, TIME, RHY 4keys, and 8 LEDs to display the status of speed & timer. Features： l 2 Winds : Normal, RHY l 4 Keys : ON/OFF, SPEED, TIME, RHY l 3 Speeds available : Low ( L ), Medium ( M ), Strong ( S ) l 2 timer setting：timer hours can be selected by OPTION, 0.5H, 1H, 2H, 4H or 1H, 2H, 4H, 8H mode l 8 LEDs : display speeds : L, M, S, RHY ; time setting : 0.5/1H, 1/2H, 2/4H, 4/8H l 3 outputs : 3 speeds: L, M, S l ON/OFF KEY : memorize the last status, except timer l 47 seconds RHY circulation l W/buzzer output Block Diagram : OSCI OSCO 32KHZ OSC COUNTER BUZZER OUT BO RHY S RHY ROM ON/OFF SPEED RHY TIME SPEED CONTROL M L KEY CONTROL 0.5/1H MEMORY TIMER 1/2H CONTROL 2/4H 4/8H Rev 1.0 July 14,2000 1/7 光碁科技股份有限公司 Ceramate Technical Co., Ltd. CP8109 Function : A. ON/OF key : 1ST pressing on ON/OFF is ON, and 2nd pressing is OFF. Each pressing makes buzzer bi B. SPEED key : When fan works, it will automatically start at SPEED L with the light of LED L. Once SPEED key pressed again, from SPEED L to SPEED M, LED L lights off & LED M lights on. The next pressing is from SPEED M to SPEED S, and the following from SPEED S to SPEED L. The action Là M à S à L à M, accompaning with LED display & buzzer bi, makes a circulation. Each pressing makes buzzer bi a sound. C. TIME key : When TIME pressed, LED 0.5H (1H) lights on as 0.5hr (1hr) time setting. Pressed again, LED 0.5H (1H) lights off & LED 1H (2H) lights on as 1 (2) hrs time setting. Timer action as same as LED display, OFF→0.5H(1H)→1H(2H)→2H(4H) →4H(8H)→OFF, makes a cycle. Each pressing makes the buzzer bi a sound. LED displays the remaining time. 2 (4) hrs later, if timer is set at 4H (8H), LED 2H (4H) lights on & LED 4H (8H) lights off. It means 2 (4) hrs left. Then, after 1(2) hr, LED 1H (2H) lights on & 2H (4H) off; It means 0.5 (1) hr left. After the last 0.5 (1) hr, fan and all LEDs light. D. RHY key : When fan is ON, it is in status of Normal wind. When RHY key pressed, it turns to RHY status, accompanied with RHY LED light ON. When pressed again, it turns to OFF & RHY LED lights OFF. Each pressing makes the buzzer bi a sound. E. BUZZER bi: 4KHz F. Oscillation frequency: 32.768KHZ。 Rev 1.0 July 14,2000 2/7 光碁科技股份有限公司 Ceramate Technical Co., Ltd. CP8109 RHY Mode : In RHY mode, LED RHY ON displays the present RHY status. LED displaying the speed simultaneously changes with SPEED. Speed cycle of RHY is as follows: Rev 1.0 July 14,2000 3/7 光碁科技股份有限公司 Ceramate Technical Co., Ltd.
