Design based on the Ember EM250 or the STMicroelectronics SN250 Integrated RC oscillator (10 kHz) for low power operation Less than 3uA current consumption in Deep Sleep mode Pins available for non-intrusive debug interface (SIF) Wide input voltage range (3.4 9 VDC) (alternate configuration for 2.2-3.6VDC) FCC Compliant Applications Sensor networks Remote monitoring and security Industrial and Lighting controls Home automation and control Description Ciphers URMA-2450 is a high power output, low power consumption ZigBee module based on the EM250 or SN250 ZigBee Network Processor which integrates a 2.4 GHz, IEEE 802.15.4-
compliant transceiver with built-in PHY and MAC, along with an adjustable Power Amplifier (PA) and Low Noise Amplifier (LNA). This ZigBee module enables OEMs to easily add wireless networking capability to their electronic devices, providing a comprehensive solution to create sensor and control networks with meshing and self healing capabilities. A 24 MHz high stability crystal provides the timing requirements as per ZigBee specifications. An internal RC oscillator allows low power operation. The Deep Sleep mode, with power consumption less than 3 A, allows applications where the battery life is a key point. An on board regulator (LDO) allows input voltage up to 9VDC. For applications supplying power at less than 3.6V, an alternate configuration of the module (without the regulator) allows for input supply voltage as low as 2.2VDC with minimal reduction in output power. The URMA-2450 module includes an integrated 2.45 GHz PCB Inverted-F antenna. 128 kB Flash and 5 kB of static RAM are available for data and program storage. To support user defined applications, a number of peripherals such as GPIO, UART, I2C, ADC and general purpose timers are available and user selectable. The module can be controlled by means of a standard serial interface allowing the connection to a variety of host microcontrollers.
