RCR02

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%.
