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).
