RCR2C
CMOS IC
DECODER FOR REMOTE
CONTROLLER WITH FIVE
FUNCTIONS

DESCRIPTION
The UTC RCR2C can be used with the encoder UTC
RCT2E to provide a complete control functions to the
remote-controlled toy. The UTC RCR2C is the receiver. It is
provide five function keys to control forward, Backward,
Rightward, Leftward and Turbo motions. Beside, a
combination of these five motions can be played. And UTC
RCR2C provides the selections of Output Signal Format.
UTC RCR2C provides two high effective amplifiers and
enhancive Signal Input (SI) recognition capacity for incresing
remote control distance.
UTC RCR2C has an internal, selectable DC-DC converter
that makes the application stable, reliable under lower supply
voltage. The input voltage ranges from 0.8v ~ 3.0V, where
VOUT can be set to 3.0V. Start-up is guaranteed from 1.0V
inputs.

FEATURES
* Wide and Low operating voltage range:
1.8V ~ 5.0V(No DC-DC)
1.0V ~ 5.0V(Use DC-DC)
* 5-function output pins for control forward/ backward/ turbo/
right/ left.
* Provide two transmissive interface (RF and IR) for different
application.
* Selectable Output Signal Format through MOD pin
* Internal, Selectable DC-DC converter which need few
external components
* Provide two high effective amplifiers and enhancive signal
enput (SI) recognition capacity for very weak signal for
increasing remote control distance.

* Few external components needed and Oscillator with
an external resistor.
* Low operating current.
* Long distance Remote Control to 100M in UTC
RCT2E and UTC RCR2C pairing.
* Typical oscillator frequency:
RF: 116~140KHz.
IR: 114KHz(Carrier Frequency: 57KHz).
IR: 76KHz(Carrier Frequency: 38KHz).
