FerretTronics FT639 Servo
Controller Chip
Data Sheet
General Description:
The FT639 is an RC servo controller chip. The FT639 will
control five radio-controlled servos through one 2400 baud
serial line. It has a footprint of only eight pins. The only
external components required are two resistors and a diode for
an normal RS232 line such as the one found on a personal
computer. No components are needed for a 0-5 volt serial line
such as those found on the Parallax Basic Stamp . Just
connect the servo control lines directly to the chip and connect
the serial in line from a 2400 baud, No parity, 1 stop bit serial
source, and five RC servos can be controlled, (see circuit
setup).
Applications:
Radio control servo motors are used in remote control model
airplanes, cars, and boats. They are widely available and can be
used in robotics, automation, animation, and many other tasks.
The problem with using RC servo motors in the past was the
ability to control them. With the FT639 this is no longer a
problem. It is possible now to control five RC servo motors
with just one 2400 baud serial line. Each of the five RC servos
is independently controlled.
