Figure 1. MC1321x 系統(tǒng)級(jí)方框圖

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.
