The PT8A977P/977W has five input pins corresponding with the five function buttons i.e, forward, backward, rightward, leftward and turbo. The encoding circuit in the PT8A977P/977W 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. The PT8A978P (or 978LW) has five output pins corresponding with the five actions. 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 PT8A977P/977W and 978P/978LW 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 PT8A977P/977W and PT8A978P/978LW 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. .oNtraP.oNtraP .oNtraP .oNtraP.oNtraPegakcaPegakcaP egakcaP egakcaPegakcaP P779A8TPPIDnip-41 W779A8TPCIOSnip-41 P879A8TPPIDnip-61 WL879A8TPCIOSnip-61 Ordering Information Data Sheet PT8A977P/977W/978P/978LW 5-Function Remote Controller PT0074(10/01) Ver:1 2 ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||| Block Diagram of 978P/978LW OSCI OSCO Right Turbo Forward Backward Oscillator Timing Generator Decoding Circuit Latch Output Circuit Signal Sample & Fault-Tolerant Amp.
