    Kit Overview

    The eZ430-ChronoseZ430-Chronos is a highly integrated, wearable wireless development system based for the CC430 in a sports watch. It may be used as a reference platform for watch systems, a personal display for personal area networks, or as a wireless sensor node for remote data collection.

    Based on the CC430F6137CC430F6137 <1 GHz RF SoC, the eZ430-Chronos is a complete CC430-based development system contained in a watch. This tool features a 96 segment LCD display and provides an integrated pressure sensor and 3-axis accelerometer for motion sensitive control. The integrated wireless feature allows the Chronos to act as a central hub for nearby wireless sensors such as pedometers and heart rate monitors. The eZ430-Chronos offers temperature and battery voltage measurement and is complete with a USB-based CC1111CC1111 wireless interface to a PC.

    The eZ430-Chronos watch may be disassembled to be reprogrammed with a custom application and includes an eZ430 USB programming interface.


    • Small form factor and ultra-low-power consumption
    • Expandable for Personal Area Network applications
    • Based on CC430: MSP430™ MCUs with integrated <1 GHz RF
    • Low cost development system


    Key Applications:  Automotive and Transportation, Communications and Telecom, Consumer Electronics, Energy and Lighting, Industrial, Medical
