Encoder / Decoder IC’s
RF803
Transmitter Encoder RF803E
Functional Description
The RF803E is a simple device to use. As shown in the application circuit below, it requires only the
addition of input switches and RF circuitry for use as the transmitter in the end application.
Transmission is automatic without user intervention.
On detecting a switch closure The RF803E will wake up transmit a secure data packet on the TX
output.
The RF803E uses a fully balanced Manchester encoded data protocol designed for optimum use of
the radio transmission path.
Each RF803E is programmed at the time of manufacture with a unique 16-bit serial number, which
provides a secure way of addressing RF800 series devices. This provides up to 65,536 possible
addresses.
Compatibility with RF Solutions Receivers
The RF803 series are compatible with the FireFly/FireBlade series and 210-433/525/458 series of
ready to operate receiver decoder units.
This enables a designer to easily integrate a remote control function into an application using a
ready made receiver
