光碁科技股份有限公司 Ceramate Technical Co., Ltd. CP8112B-L8SN24 General Description : CP8112B-L8SN24 IC is the control IC of remote fan, built-in ON/OFF, SPEED, TIME, RHY/SLP,OSC 5keys, and 7 LEDs to display the status of speed & timer. Features : l 3 Winds : NORMAL, RHY, SLP l 5 Keys : ON/OFF, SPEED, TIME, RHY/SLP, OSC l 3 Speeds available: Low(L), Medium (M), Strong(S) l 7 LEDs : display speeds: L, M, S ; Time setting: 2H, 4H, 8H; SLP l 4 outputs : 3 speeds: L, M, S & OSC l ON/OFF KEY : memorize the last status, except timer l 47 seconds RHY circulation l SLP for at longest 4 Hrs time setting l ON/OFF, SPEED, TIME, RHY/SLP, OSC also controlled by remote l Co-operation remote control IC: CP8223R l w/buzzer output Block Diagram : OSCI OSCO 32KHZ OSC COUNTER/TIMER BUZZER OUTPUT BUZZER OUTPUT CKT S M L REMOTE DECODER CODE LED SPEED CONTROL LED LED LED LED LED LED LED SLP 2H 4H 8H S M L ON/OFF SPEED TIME RHY/SLP OSC KEY/ROMOTE CONTROL OSCILLATING RHYROM OSC OUTPUT Rev 1.0 July 15,2000 1/8 光碁科技股份有限公司 Ceramate Technical Co., Ltd. CP8112B-L8SN24 Function : A. ON/OFF key : 1ST pressing on ON/OFF is ON, and 2nd pressing is OFF. Each pressing makes buzzer bi a sound. B. SPEED key : When fan works, it will automatically start at SPEED L and LED L lights on. 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. C. TIMER key : When TIME pressed, LED 2H lights on as 2hr setting. When TIME pressed again, LED 2H lights off & LED 4H lights on as 4 hrs setting. Timer action, as same as LED display makes a cycle as OFF à 2H à 4H à 8H à OFF. Buzzer bi also sounds with each pressed key. LED displays the remaining time. For example, when 6 hrs later, timer setting at 8 hrs, LED 2H lights on & LED 4H lights off. That is only 2hrs remained. Then, the last 2hr later, all the LED light off & fan off. D. RHY/SLP key : Fan is ON, in the normal wind. Upon RHY/SLP key pressed, it turns to RHY and the LED displaying the speed blinks. RHY/SLP key pressed again, LED SLP, and LED 8H light on. Time set automatically at 8 hrs. TIME key offers the selection of time setting. But in the SLP, timer automatically starts to set at 8H. Each pressing makes buzzer bi a sound. E. OSC KEY : When OSC key is pressed, in fan’s working, OSC works. The key pressed again, OSC stops. Each pressing makes the buzzer bi a sound. F. BUZZER bi: 4KHz. G. Oscillation frequency: 32.768KHZ. H. Function of remote controller keys: same as above. Rev 1.0 July 15,2000 2/8 光碁科技股份有限公司 Ceramate Technical Co., Ltd. CP8112B-L8SN24 RHY Mode : In RHY mode, LED displays the present status in RHY L, M, or S. When RHY L pressed, LED L blinks; and the same action is with RHY M & S. LED display changes with RHY MODE L, M, or S but not with SPEED. Speed cycle of RHY is as follows: Rev 1.0 July 15,2000 3/8 光碁科技股份有限公司 Ceramate Technical Co., Ltd. CP8112B-L8SN24 SLP MODE : NOTE：A．If SPEED is changed, during SLEEP MODE, SLP will be reset. B．If timer finishes the time counting, it turns to OFF.
