3 FUNCTION DECODER FOR

REMOTE CONTROLLER

DESCRIPTION

The UTC RCR03 is CMOS LST designed for the remote

controlled toy. The received signal is amplified by the

three-stage amplifier, and then the appropriate amplified

signal is sampled, fault-tolerantly checked and decoded to

control the actions of the remotecontrolled toy. There is an

oscillator in the RCR03. By adding an external resistor

conveniently, the oscillator will be construted. The oscillator

frequency can be adjusted by the external resistor. Pressing

the ON/OFF button can control the output level of the PC pin.

The UTC RCR03,the auto-power-off functionsis achieved by

an internal counter.When the RCR03 is powered on the

counter is reset and begin to count. Any received encoding

signal also reset the counter. The PC output pin will keep on

a high level until the counter counts up to about 6 minutes.

The PC output is used to control on/off state of the external

power supply.

The UTC RCR03 have four output pins corresponding with

the three actions: Forward, Backward and Left.
