    NXP Mini ARM7/LFPAK

    motion-control
    development kit

    Quick, cost-effective development of


    brushed/brushless DC motor controllers
    Use this plug-and-play kit to develop high-performance motor controllers for brushed or
    brushless DC motors. The modular design supports power boards with various power ratings.

    Key features
    Ñ ARM7-based microcontroller with 8-/10-bit A/D converter The Mini ARM7 microcontroller is a high-performance solution
    and onboard PWM that has four timers generating up to 12 PWM signals.
    Ñ Pre-programmed for brushed or brushless motor control The onboard A/D converters can also be used to interpret
    Ñ Adjustable PWM output frequency feedback from the motor, which in turn can be used to
    Ñ Input: 12 to 24 VDC accurately control motor speed.
    Ñ Output with brushed motor: 10 A at 12 V
    Ñ Output with brushless motor: 15 A at 12 V A full bridge of PH20100S MOSFETs controls motor speed
    Ñ Separate power boards available for higher-power and direction. Each MOSFET has a 100-V rating, suitable for
    applications motors up to at least 24 V DC. MOSFETs in LFPAK enable
    Ñ RS-232, JTAG, and USB ports a superior thermal design in an SO8 footprint, thus reducing
    Ñ Modular design the size of the PCB. The MOSFETs are suitable up to 10 A at
    12 V for brushed motor designs and up to 15 A at 12 V for
    The NXP Mini ARM7/LFPAK motion control development kit is brushless designs. Integrated discrete MOSFET drivers deliver
    a cost-effective tool for quickly designing high-performance significant cost and performance benefits.
    motor controllers for brushed and brushless DC motors.
    The kit includes software that enables plug-and-play
    The kit is based on a modular concept that lets the designer operation. As a result, the board can sense the type of power
    use a single control board with a selection of NXP power board being used and prevents damage from attempting to
    boards to achieve various output powers. use incompatible boards.

    As shipped, the kit uses a 10-A, 12-V power board with LFPAK. A series of LEDs and LED tables indicate circuit functionality.
    A range of other boards, with different power ratings, are also
    available on request.
    The user manual provides step-by-step instructions for
    operation and includes detailed instructions for implementing
    software changes such as PWM frequency or the control of
    dead time.

    Development support is provided on a case-by-case basis.
