• Wide supply range (1.8?C3.6 V) for compatibility with lower?voltage batteries and more robust tolerance to supply variations.
• 20?pin TSSOP package enabling denser PCB layouts and fewer board layers compared with larger packages.
• Multiple low?power modes to minimize standby current and extend battery life in portable or energy?harvesting systems.
• Up to 16 general-purpose I/Os to interface directly with sensors, indicators, and drivers without external expander ICs.

Typical Applications

• Battery?powered sensor nodes that require low active current and multiple standby modes to maximize lifetime while maintaining periodic wakeups for measurements and transmission.
• Simple industrial controls that need a reliable 16?bit core with small flash for firmware and predictable behavior under wide voltage ranges and temperature extremes.
• Consumer handheld devices with limited space where a 20?pin package and integrated I/O reduce board area and BOM cost while delivering responsive control.
• Threshold monitoring and alarm systems where deterministic wake times and low power consumption ensure long unattended operation and quick response to events.

MSP430G2102IPW20 Advantages vs Typical Alternatives
