Encoder / Decoder ICs RF803 Encoder / Decoder ICs RF803 Features 3 digital I/O Serial Data output Connects directly to RF Modules Easy Enc / Dec Pairing Function Minimal External Components Required Performs all encoding/decoding of data for Reliable Operation. Achieves Maximum Range From RF Modules Fast Activation / Deactivation Time Up to 15 Transmitter Pairings Compatible with FireFly, FireBlade and 205 series Transmitters 1 6 Sleep mode, for battery saving RF803E 2 5 One to many / many to one relationship. 3 4 1 8 Applications Remote control 2 7 RF803D Radio Telemetry 3 6 RFID 4 5 Description The RF803 series are encoder and decoder devices. When combined with a Radio transmitter/receiver they may be used to create a remote control system with up to 3 I/O lines. The decoder IC incorporates an easy learn pairing procedure to create a relationship between encoder and decoder. RF800 Series ICs perform all the necessary data manipulation and encoding/decoding of data for an optimum range reliable radio link whilst providing a simple user interface. In addition all RF800 series chipsets compatible with the RF Solutions range of remote control transmitter or receiver meaning that custom designs using any RF800 part can be used with an off the shelf counterpart.

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 DDSS880033--77 AApprriill 0044 22000088 RRFF SSoolluuttiioonnss LLttdd,, wwwwww..rrffssoolluuttiioonnss..ccoo..uukk PPaaggee 22 TTeell 0011227733 889988000000 FFaaxx 0011227733 448800666611
