UTC UNISONIC TECHNOLOGIES CO., LTD. 1 Q W - R 5 0 2 - 0 2 6 , A 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 V OUT 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). DIP-16
