RCR2E
Preliminary
DECODER FOR REMOTE
CONTROLLER WITH FIVE
FUNCTIONS
CMOS IC
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
FEATURES
* The UTC RCR2E works as decoder
* RCR2E-A have not ZENER
RCR2E-B built-in 3.6V ZENER
* Five Pins for five control functions
* Operating power-supply voltage:
SOP-16: 2.0V ~ 5.0V, DIP-16: 2.5V ~ 5.0V
* Auto-power-off if no press on any button in 8s or
continuously press on any button over 4 minutes
* Manual-power-off with OFF button
* On-chip oscillator with an external resistor
* On-chip reversing amplifiers
* Low operating current
