REMOTE FAN MCU
GENERAL DESCRIPTION
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.
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.
