eZ430-Chronos™ Overview

1.1 Overview

The eZ430-Chronos software development tool is a highly integrated, wearable, wireless development

system that is based on the CC430F6137. 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 CC430F6137 sub-1-GHz RF SoC, the eZ430-Chronos is a complete development system

featuring a 96-segment LCD display, an integrated pressure sensor, and a three-axis accelerometer for

motion sensitive control. The integrated wireless interface allows the eZ430-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 custom applications and

includes an eZ430 USB programming interface.

eZ430-Chronos Features

• Fully functional sports watch based on the CC430F6137, an MSP430™ microcontroller with integrated

sub-1-GHz wireless transceiver

• Watch can be reprogrammed for custom wireless applications

• Highly integrated watch includes on-board three-axis accelerometer, pressure sensor, temperature

sensor, and battery voltage sensor

• 96-segment LCD display driven directly by the CC430 microcontroller

• Can be paired wirelessly with heart-rate monitors, pedometers, or other devices based on RF

transceivers such as the CC430 or CC11xx devices

• Includes an eZ430-RF USB emulator that connects the eZ430-Chronos to a PC for real-time in-system

programming and debugging.
