2.2 Featured products
This demo consist of several Freescale products whose main features are listed below.
2.2.1 Triple Axis Accelerometer MMA7260Q
The ZSTAR board is a demonstration tool for the MMA7260Q, a 3-Axis Low-g accelerometer. The
MMA7260Q has many unique features that make it an ideal solution for many consumer applications,
such as freefall protection for laptops and MP3 players, tilt detection for e-compass compensation and
mobile phone scrolling, motion detection for handheld games and game controllers, position sensing for
g-mice, shock detection for warranty monitors, and vibration for out of balance detection.
Features such as low power, low current, and a sleep mode with a quick turn on time, allow the battery
life to be extended in end applications. The 3-axis sensing in a small QFN package requires only a 6mm
x 6mm board space, with a profile of 1.45mm, allowing for easy integration into many small handheld
electronics.
There are several other derivatives of the MMA7260Q:
• MMA7261Q with a selectable 2.5g to 10g range
• MMA6270Q is an XY dual axis accelerometer
• MMA6280Q is an XZ dual axis accelerometer
All members of this sensor family are footprint (QFN package) compatible which simplifies evaluation and
design of the target application.
2.2.2 Microcontroller MC9S08QG8
The MC9S08QG8 is a highly integrated member of Freescale’s 8-bit family of microcontrollers based on
the high-performance, low-power consumption HCS08 core. Integrating features normally found in larger,
more expensive components, the MC9S08QG8 MCU includes a background debugging system and
on-chip in-circuit emulation (ICE) with real-time bus capture, providing a single-wire debugging and
