UTC RCR03
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.
