MICROPROCESSOR
The primary component of the FreeStar Pro module is Freescale’s third generation ZigBee platform. It incorporates a
complete, low power, 2.4 GHz radio frequency transceiver, 32-bit ARM7TDMI-based microprocessor, hardware acceleration
for both IEEE 802.15.4 MAC and AES security plus a full suite of processor peripherals.
The MC1322xV architecture offers superior processing power for ZigBee applications. The core operates up to 26 MHz.
An 80 kByte ROM is utilized for the low level IEEE 802.15.4 MAC and PHYsical layer commands. This off loads the Flash
memory, leaving more space for the end user application. The MC1322xV supports 128 kBytes of Flash memory. The
program code is mirrored in 96 kBytes of RAM for faster execution by the processor core. A full set of peripherals and Direct
Memory Access (DMA) capability for transceiver packet data are also included.
In addition, the MC1322xV provides extensive power savings options, including low current sleep modes allowing for
maximum operating life when battery-powered.
The MC1322x family is available as two part numbers. These device types differ only in their ROM contents, all other
device hardware, performance, and specifications are identical:
ANTENNA
FreeStar Pro modules include an integrated PCB trace antenna. An optional MMCX connector can be specified, enabling
connection to a 50-ohm external antenna of the user’s choice. See Ordering Information on page 1.
The PCB antenna employs an F-Antenna topology that is compact and supports an omni-directional radiation pattern.
To maximize antenna efficiency, an adequate ground plane must be provided on the host PCB. Correctly positioned, the
ground plane on the host board under the module will contribute significantly to antenna performance.
The position of the module on the host board and overall design of the product enclosure contribute to antenna perfor-
mance. Poor design affects radiation patterns and can result in reflection, diffraction, and/or scattering of the transmitted
signal.
Here are some design guidelines to help ensure antenna performance:
•
•
•
•
•
•
•
Never place the ground plane or route copper traces directly underneath the antenna portion of the module.
Never place the antenna close to metallic objects.
In the overall design, ensure that wiring and other components are not placed near the antenna.
Do not place the antenna in a metallic or metallized plastic enclosure.
Keep plastic enclosures 1cm or more from the antenna in any direction.
MC13224V - this is the original version and is the generic part type.
MC13226V - this is a more recent version and is provided specifically for ZigBee-2007 Profile 2 (Pro)
applications. Only the onboard ROM image has been changed to optimize ROM usage for the ZigBee Pro profile
and maximize the amount of available RAM for application use.
- The MC13224V is intended for most IEEE 802.15.4 applications including MAC-based,
- It has a more complete set of peripheral drivers in ROM.
- The IEEE MAC/PHY functionality has been streamlined to include only that functionality
- For a typical application, up to 20 kbytes more of RAM is available versus the M13224V
- Some drivers present in the MC13224 ROM have been removed and these include the ADC,
- The Low Level Component (LLC) functionality has also been streamlined for the ZigBee Specification.
