Our design team was asked to develop a wireless system to demonstrate a triaxial accelerometer (Freescale MMA7260QT). The goal was to replace the serial cable of the original RD3112MMA7260Q (STAR) demo by a wireless connection using the latest Freescale technology to transfer accelerometer values from sensor to PC in real time.
Key features of the wireless demo include:
- Very small footprint (both hardware and software)
- Low power
- Battery powered
- 20 meter wireless range
- Printed wire antenna
- Real-time response
- Low cost
- May be used as a reference design

Latest additions to KA MCU family designed to enhance integration and performance for consumer and industrial applications
Freescale Semiconductor has added two devices to its ultra-low-end 8-bit RS08KA microcontroller (MCU) family. Freescale’s MC9RS08KA8 (KA8) and MC9RS08KA4 (KA4) MCUs are designed for applications with space and price constraints, such as home appliances and portable medical equipment.
The MC9RS08KA8/4 devices offer a robust support environment and a pin-compatible route into MC9S08QG/SH and MC9S08QA4/2 devices for designers who need to add new functionality to their designs. Shared peripherals and a common set of development tools help make the KA8/4 devices easy for engineers to leverage for their design investment.
The KA8/4 devices feature standard on-chip modules including a very small and highly efficient RS08 CPU core, up to 254B RAM,, up to 8KB flash and an analog-to-digital (ADC) converter (available on the KA8), providing customers with a higher level of integration.
