LR/WPAN PAN802154HAR Application Notes
Doc Number: Rev A3

Q15: What kind of battery life is expected?
A: The battery-life for the PAN802154 is entirely dependent on the application. In applications that only
require only a few transmissions per hour, batteries may last several years, alternately, in applications
that require continuous transmissions batteries may only last a few months.
Q16: How big is the Freescale ZigBee stack?
A: Version 1.0 stack size is dependent on the device type. Below is a simple table for current sizes of
ZigBee stack + 802.15.4 MAC, including security. More code-size reduction efforts are taking place.
Coordinator: 54,714 bytes
Router: 51,705 bytes
Node: 43,053 bytes
Note that with this code size, for the GT60 MCU a fair amount of ROM (equals to 60Kbytes minus the
amount used above for each type) is still available from the Flash to store the application program. The
above code size is expected to be substantially smaller in future releases.
Q17: Can I use the PAN802154 with another protocol stack other than the Freescale ZigBee
stack?
A: Yes. As long as the replaceable stack is compatible with the Freescale provided 802.15.4 PHY /
MAC; and it is also compiled for the GT60 MCU and MC13193 Transceiver.
Q18: Can I use the PAN802154 with the SMAC only for my simple legacy system?
A: Yes. For simple legacy application program, you can just use the SMAC only.
