Using micro machining and integrated circuit technology, Freescale produces highly reliable, capacitive,
acceleration sensors. Freescale's sensor technology can be used in a number of applications including
medical, appliance, consumer, and industrial areas such as washing machines, gaming, LCD projectors,
tracking boards, and robotics. This application note outlines how the Triax demonstration application is
written and configured. Basic demonstration program operating instructions can be found in AN3230,
MC1321x Accelerometer Demonstration Program Quick Start Guide.

The SRB introduces users to the MC13213 2.4 GHz wireless data transceiver and low power, low cost
8-bit MCU integrated into a single package. The SRB includes a USB port configured as a virtual
communications port, background debug module (BDM) for in-circuit hardware debug and programming,
switches, LEDs, 3-axis accelerometers and a buzzer. This provides users with a small, low-cost
development platform for establishing wireless data networks.
The SRB is a 2 inch by 3 inch reference board that can be configured as a network node that contains the
MC13213 transceiver/MCU System in a Package (SiP), a 16 MHz crystal, and a printed circuit antenna.
Also included is a Freescale MMA7260QR2 3-axis accelerometer that has four g-force settings:
The accelerometer also has a power saving enable pin. See the MMA7260Q Data Sheet for more details.
Four switches and four LEDs are available for application and user interaction. The SRB derives its power
from either the USB port or a 2.1 mm power connector that allows an input supply voltage range of 5 to 9
VDC.
For a more in-depth description of the SRB, refer to the MC13213-EVK User's Guide
(MC13213EVKUG).
