Description

SPZB250 is a low power consumption ZigBee module based on SN250 ZigBee Network Processor which integrates a 2.4GHz, 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 sensors with meshing and self healing capability as required in a WSN scenario.

24 MHz high stability Xtal is available aboard the module to perform the timing requirements as per ZigBee specifications. An additional 32.768 kHz Xtal is provided for low power operation.

A single supply voltage is requested to power the module. An integrated 2.5 GHz specific Murata antenna is aboard. The voltage supply also determines the I/O ports level allowing an easy interface with the host system.

128k flash and 5kbytes 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 deep sleep mode with power consumption of less than 1 uA allows applications where the battery life is a key point.
