MC1321x Introduction
The MC1321x family is Freescale’s second-generation ZigBee platform which incorporates a low power
2.4 GHz radio frequency transceiver and an 8-bit microcontroller into a single 9x9x1 mm 71-pin LGA
package. The MC1321x solution can be used for wireless applications from simple proprietary
point-to-point connectivity to a complete ZigBee mesh network. The combination of the radio and a
microcontroller in a small footprint package allows for a cost-effective solution.
The MC1321x contains an RF transceiver which is an 802.15.4 Standard-compliant radio that operates in
the 2.4 GHz ISM frequency band. The transceiver includes a low noise amplifier, 1mW nominal output
power, PA with internal voltage controlled oscillator (VCO), integrated transmit/receive switch, on-board
power supply regulation, and full spread-spectrum encoding and decoding.
The MC1321x also contains a microcontroller based on the HCS08 Family of Microcontroller Units
(MCU) 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 applications that use a stack from 3rd party vendors.
The MC13214 is a fully compliant ZigBee platform. The MC13214 contains 60K of flash and 4KB
of RAM and uses the Figure 8 Wireless ZigBee Stack (Z-stack) software. Applications can be
added to develop fully certified ZigBee products
Applications include, but are not limited to, the following:
Residential and commercial automation
— Lighting control
— Security
— Access control
— Heating, ventilation, air-conditioning (HVAC)
