SM3015
REMOTE FAN MCU
GENERAL DESCRIPTION
SM3015 is a multi-function Fan Controller
CMOS IC that can be applied to a variety of
con s u m e r p r o d u c t s . I t h a s a n e l a s t i c
function like MCU but does not need
programming, user can just write a MASK
form.
SM3015 has three or four wind modes;
normal, rhythm and sleep-rhythm wind or
normal, rhythm, sleep-normal and sleep-
rhythm, the operation pattern of rhythm and
sleep modes can be set by user.
Many kinds of timer setting and two swing
head control that include micro-swing output
can be chosen by user to tune the swing
head angle.
Memory or non-memory function is
available; the Speed, Mode, Swing functions
will operate as last state in memory type.
Supports two-bit customer codes to
distinguish different models.
FEATURES
* High performance CMOS technology.
* Rhythm wind or Normal wind for SLEEP
mode can be chosen.
* Two to three-wind grade control in wind
modes.
* Memory start-up function option.
* Many types of timer setting on three or four
steps and ladder adder or non-ladder
adder.
* Two swing head control, micro-swing output
can be chosen by MASK option.
* SPEED or ON/OFF key can enable fan
controller.
* 16 or 32 patterns per cycle of rhythm/sleep
mode, each pattern has 2.5 sec.
* Panel control or pair with SM5021B for an
infrared Remote Fan Controller.
* 16/18/20/22/24 pin plastic DIP package.
* Three types of sleep hold time by SLT key:
0.5hr/1hr/2hr.
* 32.768KHz/455KHz oscillator option.
APPLICATIONS
* Electronic Fan
* Heater Fan
* Air-Cleaner
* Dehumidifier
* Humidifier

REMOTE FAN MCU
FUNCTION DESCRIPTION
SM3015 has two control types : panel keypad and infrared remote control.
There are four to eight control signal operations :
* Start-up by SPEED key
a. function turn off (OFF key)
b. wind mode select (MODE key)
c. start-up function and wind speed select (SPEED key)
d. timer setting (TIMER key)
e. swing head or tuner for swing angle (SW1 and SW2 key)
f. lighting control (LIGHT key)
* Start-up by ON/OFF key
a. function control (ON/OFF key)
b. wind mode select (MODE key)
c. wind speed select (SPEED key)
d. timer setting (TIMER key)
e. swing head or tuner for swing angle (SW1 and SW2 key)
f. lighting control (LIGHT key)
All functions can be planned by user like an MCU for more product application.
Only SPEED or ON/OFF key can enable the fan controller, except for the light control. Wind mode,
timer and swing head inputs can not be accepted when fan is not activated. The fan controller will be
turned off by timer and OFF (ON/OFF) key inputs.
When more than one key are pressed, controller will not accept the multi-key's control signal, if the
panel keys are pressed more than six seconds, controller will generate a " BI-BI-BI-BI" warning sound.
When fan is enabled by SPEED or ON/OFF key, the initial state of fan controller is as follows:
* Memory function available
If Fan controller is OFF on sleep mode, all memory functions will be returned to the LAST TURN
ON STATE.
a.Grade as last state but with starting medium wind for three seconds (MASK option)
b. The wind mode as last state except sleep mode
c. Swing function as last state
d. Timer setting off
e. Light is independent
* Non-memory function (Bonding option)
a. Grade is low wind function but with starting medium wind for three seconds (MASK option)
b. Normal wind mode operation
c. Timer setting and swing head off
d. Light is independent
