REMOTE CONTROLLER WITH FIVE FUNCTIONS

General Description

The TX2C ATS302T/RX2C ATS302R are a pair of CMOS LSIs designed for remote

controlled car applications. TX2C ATS302T is the encoder and RX2C ATS302R is the

decode. They provide five function keys to control forward, Backward, Rightward,

Leftward and Turbo motions. Besides, a combination of these five motions can be played.

And RX2C ATS302R provides the selections of Output Signal Format about FORWARD

function.

TX2C ATS302T is built with auto Power-OFF function. When input key is pulled low,

TX2C ATS302T will wake up, SO and SC will continuously send out the outputs used in

wireless (Non-Carrier) and infrared (Carrier) applications respectively. When a complete

code is sent out and all the keys are open, TX2C ATS302T will automatically go into

power-off mode.

RX2C ATS302R provides two high effective amplifiers and enhancive Signal Input (SI)

recognition circuit for increasing remote control distance.

RX2C ATS302R has an internal, selectable DC-DC converter that makes the application

stable, reliable under lower supply voltage. The input voltage ranges from 0.8v to 3.0V,

where V

_OUT

can be set to about 2.8V. Start-up is guaranteed from 1.0V inputs.

Features

Wide and Low operating voltage range:

1.5V to 5.0V(TX2C ATS302T and RX2C ATS302R No using DC-DC)

1.0V to 3.0V(RX2C ATS302R Using DC-DC)

5-function remote controller controlling forward/ backward/ turbo/ right/ left

Provide two transmissive interface (RF and IR) for different application

Selectable Forward Output Signal Format through MOD pin

Few external components needed and Oscillator with an external resistor and a

capacitance.

Low Standby current and low operating current.

Typical oscillator frequency:

RF: 128KHz

IR: 114KHz(Carrier Frequency: 57KHz)

IR: 76KHz(Carrier Frequency: 38KHz)

Auto Power-OFF function for TX2C ATS302T

Internal, Selectable DC-DC converter which need few external components

Provide two high effective amplifiers and enhancive signal input (SI) recognition

circuit for very weak signal for increasing remote control distance.

Absolute Maximum Ratings

Comments*

Never allow a stress to exceed the values listed under "Absolute Maximum Ratings", otherwise the device would suffer from a permanent damage. Nor is a stress at the listed value be allowed to persist over a period, since an extended exposure to the absolute maximum rating condition may also affect the reliability of the device, if not causing a damage thereof.
