GS 鈥?02
Flexible Remote Control (FRC) Technology 鈩?Transmitter
GENERAL DESCRIPTION
The
GS 702
transmitter controller has been designed in order to meet the requirements of
replacement remote control makers. It鈥檚 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.
