ZSTAR3 Wireless Sensing Triple Axis Reference Design
Introduction
2.1
The Wireless Sensing Triple Axis Reference Design (ZSTAR3) was designed as a new generation of the
previous ZSTAR (RD3152MMA7260Q) demo. A 2.4 GHz Radio Frequency (RF) link is also used in this
new demo and its based on the new solution modem and microcontroller in one package MC13213 family.
It’s used for connection between the sensor and PC, allowing visualization of key accelerometer
applications as in the previous demo.
The demo consists of two boards (a new one and an older one with new software):
Both sides communicate over the RF medium utilizing the freely available lightly modified software stack
Simple Media Access Control (SMAC) from Freescale.

Sensor Board (or remote board) is a new board designed for demonstrating Freescale’s new 3-axes
accelerometer solution for digital (MMA7455L, MMA7660FC) and analog (MMA7361LT)
accelerometric data sensing, and the 2.4 GHz RF modem with an HCS08 microcontroller in a one
package solution as an easy design for remote sensors.
USB stick, with the MC13191 RF front-end, and the HC08 family MCHC908JW32 for the USB
communication. This board is used from the older ZSTAR demo, but with new software.
