1.2 Applications
• Home Automation
• Security
• Sensor Management
• Data Acquisition
CAUTION These products use FRAM nonvolatile memory technology. FRAM retention is sensitive to extreme temperatures,
such as those experienced during reflow or hand soldering. See Absolute Maximum Ratings for more information.
CAUTION System-level ESD protection must be applied in compliance with the device-level ESD specification to prevent
electrical overstress or disturb of data or code memory. See the application report MSP430™ System-Level ESD
Considerations (SLAA530) for more information.
