光碁科技股份有限公司 Ceramate Technical Co., Ltd. CP8110 General Description： CP8110 IC is the control IC of fan without remote, built-in ON/OFF, SPEED/ L-RHY, TIME 3 keys, and 6 LEDs to display the status of speed & timer. Features： l 2 Winds: Normal, L-RHY l 3 Keys: ON/OFF, SPEED/L-RHY, TIME l 3 Speeds available: Low (L), Medium (M), Strong (S) ) l 2 Timer setting: timer hours can be selected by OPTION, 1H, 2H, 4H or 2H, 4H, 8H mode l 6 LEDs: display speeds: L, M, S ; time setting: 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 Block Diagram : OSCI OSCO 32KHZ OSC COUNTER S RHY ROM SPEED CONTROL M L / L - RHY ON/OFF KEY CONTROL MEMORY TIMER TIMER CONTROL 1/2H 2/4H 4/8H Rev 1.0 July 14 ,2000 1/6 光碁科技股份有限公司 Ceramate Technical Co., Ltd. CP8110 Function : A. ON/OF key : 1ST pressing on ON/OFF is ON, and 2nd pressing is OFF. B. SPEED/L-RHY control : 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 LED M to LED S, and the following from LED S to LED L. The action Là M à S à L-RHY àL à M, accompaning with LED blinking , makes a circulation. C. TIME key : When TIME pressed, LED 1H(2H) lights on as 1hr (2hrs) setting. When TIME pressed again, LED 1H (2H) light off & LED 2H(4H) light on as 2 hrs (4hrs) setting. Timer action, as same as LED display moves in circles as OFF à 1H(2H) à 2H(4H) à 4H(8H) à OFF. LED displays the remaining time. For example, when 2 (4) hrs later, timer setting at 4 (8) hrs, LED 2H (4H) lights on & LED 4H (8H) lights off. That is, there is only 1 (2) hrs remaining. Then, the last 1 (2) hr later, all the LED light off & fan off. D. Oscillation frequency: 32.768KHZ. Rev 1.0 July 14 ,2000 2/6 光碁科技股份有限公司 Ceramate Technical Co., Ltd. CP8110 L-RHY Mode : In L-RHY mode, LED L blinking displays the present status in L-RHY. LED displaying the speed simultaneously changes with SPEED.
