RCT02
CMOS IC
ENCODER FOR REMOTE
CONTROLLER WITH FIVE
FUNCTIONS
DIP-14
DESCRIPTION
The chip can be used with the decoder UTC RCR02 to provide a
complete control functions to the remote-controlled toy. The UTC
RCT02 has five input pins corresponding with the five function
buttons i.e, forward, backward, rightward, leftward and turbo. The
encoding circuit in the UTC RCT02 sends digital codes to the two
output pins SO and SC. The digital codes correspond to the definite
function buttons or their combinations. The SO and SC outputs are
used in wireless and infra-red applications respectively.
SOP-14
There is an internal oscillator in the UTC RCT02. 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 RCT02 and UTC RCR02 must be less than ±25%.
The auto-power-off function is achieved by an internal counter. When the UTC RCT02 is powered on, the counter
is reset and begin to count. Any action of push down or release the function button also reset the counter. The PC
pin will keep on a high level until the counter counts up to about 4 minutes. 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.
FEATURES
*Five input pins used for five control buttons
*Operating power-supply voltage range: 2.5 ~ 5.0V
*One output pin used for external power control
*Press on any button as wake up
*Auto-power-off if no press on any button in 4 minutes or *On-chip oscillator with an external resistor
continuously press on any button over 4 minutes
*Manual-power-on/off with ON/OFF button
*Low operating current
*Few external components needed
