General Description
The PT8A977B and PT8A9781 provide a complete
control functions to the remote-controlled toy. The
PT8A9781 has four output pins corresponding with
the four actions i.e, forward, backward, right, left.
The received signals are amplified by the three-stage
amplifier, and then 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 PT8A9781. By
adding an external resistor and capacitor conveniently,
the oscillator will be constructed. The external resistor
and capacitor can adjust the oscillator frequency. The
relative error between the frequencies of the two on-
chip oscillators in the PT8A977B and PT8A9781 must
be less than
±
25%.
Part No.
