XEMICS, represented in Australia by Electronic Development Sales , has released a DP1205 drop-in module operating in the unlicensed 433MHz, 868MHz and 915MHz bands. The DP1205 module is based upon the XE1205 transceiver and offers a simple, cost-effective way to make any wired application wireless.
Using the module is as simple as connecting it to an SPI-bus enabled microcontroller and adding an antenna. The module is fully tested and ETSI/FCC pre-certified and can operate with simple configuration.
Although the module is very simple to use it offers good performance and flexibility. With a 128dB link budget (4.8 kbit/s, 0.1% BER) a pair of modules can communicate over distances in excess of several hundred metres. It offers 15dBm transmit power, 152.34 kbit/s maximum RF data rate, 14mA receive and 45mA transmit typical current consumption.
It also has a 16-byte FIFO data buffer, an SPI-bus data link and an enhanced AFC algorithm, all of which contribute to reduced host-controller overhead and thereby lower system cost.
The DP1205 module meets the requirements for 25kHz channel spacing and adjacent channel power of less than -37dBm and is suitable for applications operating in the 433MHz-868MHz-915MHz band such as alarms, security, automatic metering, services and controls.
The modules are available in a surface-mount, manufacturing-friendly package that supports automated assembly and IR reflow. The overall dimensions of the module are 18.5mm x 30.5mm.
