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