TI’s new eZ430-Chronos revolutionizes the design of wireless networking applications

Customizable development environment within a sports watch propels development based on TI’s CC430 MCU

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

Based on the CC430F6137 <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 CC1111 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. Add to Cart!
