You also have the option to use a stand alone transceiver and MCU alternative to provide additional design flexibility. For example, the block diagram below is Freescale’s 13192 sensor application reference design for sensing, monitoring and control subsystems. Completed boards based on this design are included in our 13192DSK-A0E (developer’s starter kit) and 13192EVK-SFTE (evaluation kit) development kits.
Supporting files for the above reference designs are available via web download. The download folder includes schematics, bill of materials, gerber files and other necessary documentation for complete reference design implementation.

MC13211/212/213 ZigBee™- Compliant Platform -2.4 GHz Low Power Transceiver
for the IEEE® 802.15.4 Standard plus Microcontroller
The MC1321x family is Freescale’s second-generation ZigBee platform which incorporates a low power 2.4 GHz radio frequency transceiver and an 8-bit
microcontroller into a single 9x9x1 mm 71-pin LGA package. The MC1321x solution can be used for wireless applications from simple proprietary point-to-point connectivity to a complete ZigBee mesh network. The combination of the radio and a microcontroller in a small footprint package allows for a cost-effective solution.
The MC1321x contains an RF transceiver which is an 802.15.4 Standard compliant radio that operates in the 2.4 GHz ISM frequency band. The transceiver includes a low noise amplifier, 1mW nominal output power, PA with internal voltage controlled oscillator (VCO), integrated transmit/receive switch, on-board power supply regulation, and full spread-spectrum encoding and decoding.
The MC1321x also contains a microcontroller based on the HCS08 Family of Microcontroller Units (MCU), specifically the HCS08 Version A, and can provide up to
60KB of flash memory and 4KB of RAM. The onboard MCU allows the communications stack and also the application to reside on the same system-in-package (SIP).
The MC1321x family is organized as follows:
The MC13211 has 16KB of flash and 1KB of RAM and is an ideal solution for low cost,
proprietary applications that require wireless point-to-point or star network connectivity. The MC13211 combined with the Freescale Simple MAC (SMAC) provides the foundation for proprietary applications by supplying the necessary source code and application examples to get users started on implementing wireless connectivity.
The MC13212 contains 32K of flash and 2KB of RAM and is intended for use with the Freescale fully compliant 802.15.4 MAC. Custom networks based on the 802.15.4 Standard MAC can be implemented to fit user needs. The 802.15.4 Standard supports star, mesh and cluster tree topologies as well as beaconed networks.
The MC13213 contains 60K of flash and 4KB of RAM and is also intended for use with the Freescale fully compliant 802.15.4 MAC where larger memory is required. In addition, this device can support ZigBee 2006 applications that use Freescale’s BeeStack.
