capture, output compare, or buffered edge- or center-aligned PWM on each channel;

– RTC — (Real-time counter) 8-bit modulus counter with binary or decimal based prescaler;

external clock source for precise time base, time-of-day, calendar or task scheduling

functions; free running on-chip low power oscillator (1 kHz) for cyclic wake-up without

external components; runs in all MCU modes

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.
