UTC RCR02
Decoder For Remote Controller
With Five Functions
DESCRIPTION
The chip can be used with the encoder RCT02 to provide a
complete control functions to the remote-controlled toy. The
RCR02 has five output pins corresponding with the five
function actions i.e, forward, backward, rightward, leftward
and turbo. The received signals are amplified by the
three-stage amplifier, and then the appropriate amplified
signals are sampled, fault-tolerantly checked and decoded to
control the actions of the remote-controlled toy.
There is an internal oscillator in the RCR02.By adding an
external resistor conveniently, the oscillator will be
constructed. The oscillator frequency can be adjusted by the
external resistor.The relative error between the frequencies of
the two on chip oscillators in the RCT02 and RCR02 must be
less than ±25%.
FEATURES
*Five output pins for control functions
*Operating power-supply voltage range: 2.5 to 5.0V
*On-chip reversing amplifiers
*On-chip oscillator with an external resistor
*Low operating current
*Few external components needed
