ER400TRS

LPRS Prelimina ry Data Sheet Easy -Radio ER400TRS Transceiver The Easy-Radio ER400TRS intelligent radio transceiver incorporates Easy-Radio technology to provide a high performance, simple to use radio device that can bi-directionally transfer serial data over a range of up to 250 metres Line Of Sight (LOS). The transceiver operates on the Pan-European 433MHz frequency band from a 3.6V supply and is housed in a space saving Single-In-Line (SIL) package. Serial input and output simplify interface to host systems and the embedded software reduces design and development time significantly. This data sheet describes the electrical and physical characteristics of the device. Operation of the software is described in the ‘Easy-Radio Software Guide’, which should be read in conjunction with this data sheet. Features Crystal controlled synthesiser for frequency accuracy Highly selective front -end, 175KHz improves range 10mW Transmit RF power output, -105dBm sensitivity Serial Input & Output for transparent data transmission Low operating voltage - 3.6 Volts – Single Lithium Cell Low power consumption: <23mA in Transmit mode 17.0mA in Receive mode User programmable: Frequency of operation Data Rate Output Power Description The Easy-Radio 400 Transceiver is a complete sub-system that combines a high performance very low power RF transceiver, a microcontroller and a voltage regulator. (Figure 1) The microcontroller programmes the functions of the RF transceiver and provides the inter...
