10-Function Remote Controller  
Features  
Description  
The PT8A992AP works as the encoder and the  
PT8A993AP works as the decoder  
The PT8A992A/993A is a pair of CMOS LSIs  
designed for remote controlled toy car application. They  
have 11 control keys for controlling the corresponding  
motion (i.e. forward, backward, left, right and 7 other  
functions) of the remote controlled car.  
11 output pins, 4 for forward, backward, left and right  
functions, and 7 functional keys  
Operation power supply: 3.0V to 5.5V  
Auto power-off if no key pressed (PT8A992A)  
Low operating current  
On-chip oscillator with an external resistor  
On-chip receiving amplifiers  
Few external components needed
