DECODER FOR REMOTE

CONTROLLER WITH FIVE

FUNCTIONS

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
