Applications

SPZB250

ZigBee® module

Description

SPZB250 is a low power consumption ZigBee® module based on EM250 ZigBee chip which integrates a 16 bit processor together with a 2.4 GHz, IEEE 802.15.4-compliant transceiver as well as IEEE 802.15.4 PHY and MAC. It enables OEMs to easily add wireless networking capability to any electronic device. Such a module is a very comprehensive solution to build wireless sensors with meshing and self healing capability as required in a WSN scenario.

24 MHz high stability crystal is integrated in the module to perform the timing requirements as per ZigBee

specifications. An additional

32.768 kHz crystal is provided for low power operation.

To support user defined applications, a number of peripherals such as GPIO, UART, I general purpose timers are available and user selectable.

■ Industrial controls

■ Sensor networking

■ Monitoring of remote systems

■ Home applications

■ Security systems

■ Lighting controls

The deep sleep mode with power consumption less than 2 μA (typ) allows the use in applications where the battery life is a key constraint.

For other information and details, please refer to EM250 datasheet available at the Ember Corporation website.
