Features

General Description

• The PT8A990P works as the encoder and the

PT8A991P works as the decoder

The PT8A990P/991P is a pair of CMOS LSIs designed

for remote controlled toy car application. They have nine

control keys for controlling the corresponding motion (i.e.

forward, backward, left, right, turbo and 4 functional keys)

of the remote controlled car. They also have ‘Forward

(Backward)’ and ‘Turbo’ combination application.

• Nine output pins, 5 for forward, backward, left,

right and turbo functions, and 4 functional keys

• Operation power supply: 3.0V to 5.5V

• Auto power-off if no key pressed within 2s

(PT8A990P)

• Auto shut-down if keep pressing a key for more

than 4 minutes (PT8A990P)

• Auto shut down if no signal input for more than 5

minutes (PT8A991P)

• Low operating current

• On-chip oscillator with an external resistor

• On-chip receiving amplifiers

• Few external components needed
