Freescale Semiconductor's MC13226V platform is pin-for-pin compatible with the MC13224, but has a new ROM firmware version 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 to maximize the amount of available RAM for application use.
-
The IEEE® MAC/PHY functionality has been streamlined to include only that functionality required by the ZigBee specification. The MAC functionality is 802.15.4 compatible.
-
Some drivers present in the MC13224 ROM have been removed. These include the ADC, LCD font and SSI drivers. These drivers are still available as library functions, but now compile into the RAM space.
-
The low level component (LLC) functionality has also been streamlined for the ZigBee specification.
Note: The MC13226 requires BeeKit 1.9.17 or later and IAR Embedded Workbench 5.5
