PT8A977B/978B/978BL 5-Function Remote Controller Features Description • PT8A977B works as encoder and PT8A978B/ The PT8A977B and PT8A978B (or 978BL) provide 978BL works as decoder complete control functions to the remote-controlled toy. • Five pins for five control functions The PT8A977B has five input pins corresponding with • Operating power-supply voltage: 2.5V to 5.0V (978B), the five function buttons i.e, forward, backward, rightward, 2.0V to 5.0V (978BL), 1.8V to 5.0V(977B) leftward and turbo. The encoding circuit in the PT8A977B • Auto-power-off and oscillation-off if no press on sends digital codes to the two output pins SO and SC. any button (977B) The digital codes correspond to the definite function • Press on any button to wake up (977B) buttons or their combinations. The SO and SC outputs • One output pin used for external power control are used in wireless and infra-red applications (977B) respectively. • On-chip oscillator with an external resistor • On-chip reversing amplifiers (978B, 978BL) The PT8A978B (or 978BL) has five output pins • Low operating current corresponding with the five actions. The received signals • Few external components needed are amplified by the three-stage amplifier, and then the • Package: 14-pin DIP, 14-pin SOIC, appropriate amplified signals are sampled, fault-tolerantly 16-pin DIP checked and decoded to control the actions of the remote- , 16-pin SOIC, die form and wafer form controlled toy.

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 PT8A977B and PT8A978B/978BL must be less than ±25%. The auto-power-off function is achieved by an internal counter (977B). The PC output is used to control on/off state of the external power supply. Press on any function button will wake up the chip promptly.
