RCR2E

DESCRIPTION 

The UTC RCR2E provides a complete control 

functions to the remote-controlled toy. 

The UTC RCR2E has five output pins corresponding 

with the five actions. The received signals are amplified by 

the three-stage amplifier, and than 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 UTC RCR2E

respectively. 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 UTC RCR2E must be less than ±25%. 

The auto-power-off function is achieved by an internal 

counter. The PC output is used to control on/off state of 

the external power supply. Pressing OFF button can also 

shut down the power supply. Press on any function button 

will wake up the chip promptly
