The MC12311 is a highly-integrated, cost-effective,
system-in-package (SIP), sub-1GHz wireless node
solution with an FSK, GFSK, MSK, or OOK
modulation-capable transceiver and low-power HCS08
8-bit microcontroller. The highly integrated RF
transceiver operates over a wide frequency range
including 315 MHz, 433 MHz, 470 MHz, 868 MHz, 915
MHz, 928 MHz, and 955 MHz in the license-free

Software Solutions
Freescale will support the MC12311 platform with several software solutions:
• SMAC (Simple Media Access Controller) - This codebase provides simple communication and
test apps based on drivers/PHY utilities available as source code. This environment is useful for
hardware and RF debug, hardware standards certification, and developing proprietary applications.
• IEEE 802.15.4 MAC with custom PHY layer - The Freescale MAC is a robust, mature codebase
useful for developing networking solutions. Freescale is implementing an IEEE 802.15.4
MAC-compatible custom sub-1 GHz PHY template that can be used across different frequency
bands. This capability allows users to build powerful networking solutions on a known, stable
codebase.
• Wireless MBUS stack - Freescale is porting an existing wireless MBUS codebase to the MC12311
platform which will be available through an external partner.
The Freescale MC12311 solutions are provided through a powerful software environment called the
Freescale BeeKit Wireless Connectivity Toolkit. BeeKit is a comprehensive codebase of wireless
networking libraries, application templates, and sample applications. The BeeKit Graphical User Interface
(GUI), part of the BeeKit Wireless Connectivity Toolkit, allows users to create, modify, and update various
wireless networking implementations. The MC12311 products are available as codebases within BeeKit;
for the wireless MBUS stack, BeeKit will have simple demo apps only.

System-in-Package Sub-1 GHz Wireless Node
The MC12311 brings together a transceiver chip and an MCU chip on a single substrate to provide a small
footprint, cost-effective sub-1 GHz wireless node. The transceiver is controlled by the MCU through a
dedicated SPI interface. The SPI bus interface and some status signals are connected onboard the substrate
to eliminate the need for external connections.
4.1
RF Transceiver
The transceiver (see
Figure 2)
is a single-chip integrated circuit ideally suited for today's high performance
ISM band RF applications. Its advanced features set, including state of the art packet engine, greatly
simplifies system design while the high level of integration reduces the external RF component bill of
material (BOM) to a handful of passive de-coupling and matching components. It is intended for use as a
high-performance, low-cost FSK and OOK RF transceiver for robust, frequency agile, half-duplex
bi-directional RF links.
The MC12311 is intended for applications over a wide frequency range, including the 433 MHz and 868
MHz European and the 902-928 MHz North American ISM bands. Coupled with a link budget in excess
of 135 dB, the transceiver advanced system features include a 66 byte TX/RX FIFO, configurable
automatic packet handler, listen mode, temperature sensor and configurable DIOs which greatly enhance
system flexibility while at the same time significantly reducing MCU requirements. The transceiver
complies with both ETSI and FCC regulatory requirements.
Figure 2. MC12311 Transceiver Block Diagram
The major RF communication parameters of the MC12311 transceiver are programmable and most can be
dynamically set. This feature offers the unique advantage of programmable narrow-band and wide-band
communication modes without the need to modify external components. The transceiver is also optimized
for low power consumption while offering high RF output power and channelized operation.
