GS –702

Flexible Remote Control (FRC) Technology ™ Transmitter

GENERAL DESCRIPTION

The GS 702 transmitter controller has been designed in order to meet the requirements of

replacement remote control makers. It’s structure is based on Application Specific Programmable

Micro-controller with a super parallel architecture implemented by means of CMOS EPROM

technology.

GS 702 replaces most of the original transmitter ICs, used nowadays. Additionally, many

parameters and functional features have been dramatically improved. A typical remote control

implementation, shown on Fig 1 uses only four external components, and power consumption

in stand-by mode is in the range of 100nA.

In order to facilitate application project design for different type of protocols, a FRC CAD system

and Chip Programmer are available. The CAD library contains more than 30 of most popular

protocols, at present, and new ones could be developed and added by the user.
