SC2128A
FAN REMOTE CONTROL DECODER USED TOGETHER WITH SC2268
DESCRIPTION
The SC2128A is a high performance electronic fan controller LSI,
Speed control; off-timer, rhythm wind, sleep mode, head swing
and/or light control are all built into a single chip. Indicator LED
output, buzzer output, key control input, as well as remote control
decoding circuitry are all provided to build a full function electronic
fan with remote control capability having the highest performance
with the least external components. Pin assignment and application
DIP-16-300-2.54
circuit are optimized for easy PCB layout and cost saving for
electronic fan application.
