8A9701 - PT8A9701

Pericom Semiconductor Corporation

Description

The PT8A9701 and PT8A973/973L is a pair of CMOS LSIs designed for remote controlled toy car application.

They have seven control keys for controlling the corresponding motion (forward, backward, left, right, turbo and 2 functional keys) of the remote controlled car.

Features

The PT8A9701 works as the encoder and the PT8A973/973L works as the decoder.
Seven output pins, 5 for forward, backward, left, right and turbo functions, and 2 functional keys.
Operation power supply for PT8A9701: 3V to 12V (with series resistor).
Auto power-off if no key pressed (PT8A9701).
Motor current limit to meet toy safety standard HD271 (PT8A973/973L).
Low operating current.
On-chip oscillator with an external resistor.
