UTC UNISONIC TECHNOLOGIES CO., LTD. 1 QW-R502-027,B ENCODER FOR REMOTE CONTROLLER WITH FIVE FUNCTIONS
DESCRIPTION
The UTC RCT2E can be used with the decoder UTC RCR2C to provide a complete control functions to the remote-controlled toy. The UTC RCT2E is the transmitter. 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. UTC RCT2E is built with auto Power-OFF function. When input key is pulled low, UTC RCT2E will wake up, SC and SO will continuously send out code in RF format (Non-Carrier) and IR format (Carrier). However, when a complete code is sent out and the key is released, UTC RCT2E will automatically go into powered-off mode.
FEATURES
- Wide and Low operating voltage range: 1.8V ~ 5.0V * 5-function remote controller controlling forward/ backward/ turbo/ right/ left. * Provide two transmissive interface (RF and IR) for different application. * Auto Power-OFF function * Few external components needed and Oscillator with an external resistor. * Low Standby current and 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-14
