.Freesc ale MC13213: 2.4GHz RF transceiver and 8-bit MCU with 60K of Flash for

ZigBeeapplicationsThe

MC1321x

family

is

Freescale’s

second- generation

ZigBee

platform whichincorporates a low power 2.4GHz radio frequency transceiver and an

8-bitmicrocontroller

into

a

package.

The

for

wireless

applications

from

simple

proprietary

point-to- pointconnectivity

to

a

complete

The

MC1321x

also

contains

a

microcontroller

based

on

the

HCS08

Family

ofMicrocontroller

Units

(MCU),

specifically

the

HCS08

Version

A,

and

can

provide

upto

60KB

of flash memory and 4KB

of

RAM. The onboard MCU

allows thecommunications stack

and also the application to reside on the samesystem-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 lowcost, proprietary applications that require wireless

point-to-point

or

star

networkconnectivity.

The

MC13211

combined

with

the

Freescale

Simple

MAC (SMAC)provides the foundation for

proprietary applications

by supplying

the
