RCT2E
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).
