UTC RCT2E

CMOS IC

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).
