RCR2E
DESCRIPTION
The UTC RCR2E provides a plete 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
