• Multiple low?power modes to minimize standby current and extend battery life in intermittent?wake applications.

Typical Applications

• Battery?powered sensor nodes that require frequent nonvolatile state updates and minimal wake?to?sleep latencies for longer field life.
• Industrial monitoring controllers that need deterministic timing, high write endurance, and robust operation across ?40 to +85 ??C.
• Human?machine interfaces where quick data logging, low standby power, and reliable retention of calibration data are required.
• Portable instrumentation that benefits from compact code size, low operating current at 16 MHz, and nonvolatile configuration storage.

MSP430FR5947IRHAT Advantages vs Typical Alternatives

The device combines FRAM??s fast, high?endurance writes with a 16?bit core and multiple low?power states. Compared to typical flash?based microcontrollers, FRAM provides lower write energy and higher cycle life, which reduces replacement and maintenance costs in fielded systems. The wide 1.8?C3.6 V range and industrial temperature rating make it more versatile than many consumer?grade parts. The architecture favors predictable interrupt latency and compact code, which improves response time and reduces memory footprint versus many 32?bit alternatives in simple control tasks.
