Neuchtel, Switzerland XEMICS ' TrueRF XE1283 is a powerful combination of a full-featured ISM-band transceiver together with an ultra-low-power RISC microcontroller. This combination of high-power transmitter and sensitive receiver means the link budget exceeds 128 dB. Ranges of up to several kilometers can be achieved at low data rates, with an optimized RF layout and without external transmitter PA or receiver LNA, and with minimal power consumption. XEMICS is also introducing the DP1283 drop-in RF module based on the XE1283 circuit. The compact module (23 x 33.5 mm) is pre-certified to conform to ETSI/FCC regulations and is available in three frequencies. Both circuits are intended for low-power sensing networks with an emphasis on battery-powered (down to 2.4V) applications where outstanding battery life can be achieved if full use is made of the controller's power-saving modes. For example it would be suitable for automated meter reading (AMR), home automation and access control as well as voice and data over RF. Xemics , Neuchtel, Switzerland. www.xemics.com.
