UTC RCR02

The chip of the UTC RCR02 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 of the UTC RCR02 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%.
