Summary

The IEEE 802.15.4 standard is the fourth task group of the IEEE 802.15 working group, which defines Wireless Personal Area Network (WPAN) standards. The IEEE 802.15.4 market has the following advantages; low power consumption, low cost, low offered message throughput, supports large network orders up to 65k nodes, low to no QoS guarantees, and flexible protocol design suitable for many applications. The purpose for this standard is to empower simple devices with a reliable, robust wireless technology that could last for years on standard primary batteries. It is designed to allow developers to effectively use and benefit from radios based upon the standard.


This reference design is a low cost System-on-Chip (SoC) solution for the IEEE 802.15.4 standard that incorporates a complete, low power, 2.4GHz radio frequency transceiver with TX/RX switch, an 8-bit HCS08 CPU, and a functional set of MCU peripherals into a 48-pin LGA package. This product targets wireless RF remote control and other cost-sensitive applications ranging from home TV and entertainment systems to medical and supports all ZigBee node types. The Freescale's MC13237 is a highly integrated solution, with very low power consumption. The MC13237 contains an RF transceiver that is an 802.15.4 standard 2006 compliant radio that operates in the 2.4GHz ISM frequency band. The transceiver includes a low noise amplifier, 1mW nominal output Power Amplifier (PA), internal Voltage Controlled Oscillator (VCO), integrated transmit/receive switch, on-board power supply regulation, 12-bit ADC and full spread-spectrum encoding and decoding.


This design is not only limited for remote controls. It can also be used as the basis for wireless devices and other sensor-controlled application that used IEEE 802.15.4 standard. The IEEE 802.15.4 radios have the potential to be the cost-effective communications backbone for simple sensory mesh networks that can effectively carry data with relatively low latency, high accuracy, and the ability to survive for a very long time on small primary batteries.
