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
