Typical Applications

• Smart meters and energy monitoring where fast, frequent non?volatile logging and low energy per write are needed to store usage data reliably over years.
• Industrial control nodes that require deterministic state retention during power interruptions and a mix of analog inputs plus real?time timers for process control.
• Portable medical devices that rely on low supply voltage, long battery life, and secure retention of calibration or patient data between sessions.
• Motor control and power conversion front ends that benefit from multiple 16?bit timers, PWM outputs, and integrated analog measurements for closed?loop control.

MSP430FR5994IRGZT Advantages vs Typical Alternatives

The FRAM?based MCU offers faster non?volatile writes, lower energy per write, and higher write endurance than EEPROM or NOR flash alternatives. The 16?bit core delivers more compact code compared with many 32?bit options for simple control tasks, and the integrated analog and timer peripherals reduce BOM and board area. For low?voltage systems, the device runs from 1.8?C3.6 V and supports deep low?power modes, yielding longer battery runtimes versus typical microcontrollers with higher quiescent currents.
