MC12311 Development Platform Overview and Description
2.1 Introduction
The MC12311 development platform is an evaluation environment based on the Freescale MC12311
device. The MC12311 is a highly-integrated, cost-effective, system-in-package (SIP), sub-1GHz wireless
node solution with an FSK or OOK modulation-capable transceiver and low-power QE32 8-bit
microcontroller. This configuration allows users to minimize the use of external components.
The MC12311 is targeted for the following low-power wireless applications:
• Automated Meter Reading
• Wireless Sensor Networks
• Home and Building Automation
• Wireless Alarm and Security Systems
• Industrial Monitoring and Control
• Wireless MBUS Standard (EN13757-4:2005)
Freescale supplements the MC12311 with tools and software that include hardware evaluation and
development boards, software development IDE and applications, drivers, custom PHY usable with
Freescale’s IEEE 802.15.4 compatible MAC, and an available wireless MBUS solution.
The MC12311 development platform is comprised of two boards:
• 12311-Modular Reference Board (12311-MRB) - this board contains the MC12311 device with 32
MHz reference oscillator crystal, RF circuitry including antenna, and supporting circuitry. The
board can be used as a simple standalone evaluation platform or as a daughter card to the other
MC12311 development platform boards or to a custom, application specific motherboard.
— Provides compact reference design for device footprint and RF layout
— Provides pre-designed MC12311 hardware (device and function)
— Provides access to the MC12311 full set of GPIO
— Provides MCU BDM debug port
— Provides optional local 2 Mbit serial FLASH, 32.768 kHz oscillator crystal, IR “blaster” LED
and power management.
• TWR-RF Board . The TWR-RF board is a motherboard for the MC12311 and 12311-MRB
daughter boards, to enable its use within the Tower system. The TWR-RF board is a Tower
Controller Module compatible with the Freescale Tower System. The 12311-MRB + TWR-RF can
run standalone, outside the Tower system. The following list summarizes the features of the
TWR-RF Module:
