REMOTE FAN MCU
GENERAL DESCRIPTION
FEATURES
SM3015 is a multi-function Fan Controller CMOS
IC that can be applied to a variety of consumer
products. It has an elastic 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.
* 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 pin plastic DIP package.
* 32.768KHz/455KHz oscillator option.

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

fan controller is on, press SPEED key on panel or remote control handset and wind grade changes as follows:
OFF
LOW
MEDIUM
STRONG

E. TIMER KEY SETTING
SM3015 has many types of timer setting, mode A is ladder-adder and mode B is non-ladder adder for three or
four steps. Timer key will not activate when fan controller is off. These types of timer may be chosen by
bonding option.

:The SWING key pressed
* MASK OPTION :
a. SHO1 and SHO2 output can be enabled when fan controller is off.
b. SHO1 and SHO2 output functions can be chosen as a continuous outputs respectively like a
micro-swing switch to tune the swing angle.

G. MEMORY FUNCTION
Memory of speed, mode(except sleep mode) and swing functions can be set independently. Memory function
can be cancelled by Bonding option. When memory function is available, wind speed mode and swing functions
will operate as last state; if last state is sleep mode, press SPEED or ON/OFF key enable fan controller while
memory functions(Speed/Mode/Swing) will be returned to the last state before sleep mode operation.
H. STARTING WIND
Memory or non-memory type, fan controller starts with three seconds starting wind.
I. CUSTOMER CODE
SM3015 provide two-bit customer code to distinguish different product models. There are four
types, that can be set by diode.
a. Set code bit to "0", connect diode to COM1/COM2 and SWING/SW1 terminal
b. Set code bit to "1", open the circuit.
