• 12?bit ADC and multiple timers that simplify mixed?signal acquisition and precise event timing in sensor and control nodes.

Typical Applications

• Sensor nodes and data loggers that require frequent nonvolatile writes and long retention for sensor calibration and event history storage.
• Battery?powered industrial controllers where low supply voltage operation and low active power consumption extend operating life between charges.
• Human?machine interfaces and feature?rich control panels that need reliable serial interfaces for display, touch, or keypad communication.
• Portable medical and measurement instruments that demand accurate ADC readings, stable timing, and nonvolatile storage for logs and parameters.

MSP430FR5964IZVWR Advantages vs Typical Alternatives

The device combines a 16?bit MSP430 core with FRAM to deliver faster, more durable nonvolatile writes compared with flash?based microcontrollers. It supports wide supply voltages and a low operating temperature range, which improves system compatibility versus parts limited to higher voltage rails. Integrated 12?bit ADC and multiple serial interfaces reduce the need for external components. Overall, the part offers a smaller BOM, longer write endurance, and simpler data logging compared with typical flash MCU alternatives.
