MSP430FR5958IRHAT Key Features

• FRAM nonvolatile memory provides fast, low?energy writes and high endurance for frequent logging and calibration storage.
• 16?bit RISC core gives efficient code density and predictable execution for real?time control tasks.
• Low operating voltage operation from 1.8 V to 3.6 V supports battery and energy?harvesting designs with lower power budgets.
• Multiple low?power modes enable ??A?class standby and rapid wakeup to balance responsiveness and energy efficiency.
• Rich peripheral set integrates timers, ADC, and serial interfaces to reduce external component count and improve reliability.

Typical Applications

• Battery?powered sensor nodes requiring frequent nonvolatile logging and long operational life with low standby current draw.
• Industrial control panels that need deterministic behavior, nonvolatile parameter storage, and operation across standard industrial temperature ranges.
• Smart metering devices where repeated writes, long endurance, and low energy per write reduce maintenance and prolong field life.
• Consumer or portable instruments that benefit from compact MCU integration, fast FRAM writes, and multiple on?chip peripherals to lower BOM cost.

MSP430FR5958IRHAT Advantages vs Typical Alternatives

The device uses FRAM instead of flash, offering far faster write speeds and higher write endurance. That reduces latency for runtime logging and eliminates complex flash erase cycles. Compared with similar 16?bit MCUs, it typically lowers energy per write and simplifies nonvolatile data management. The broad operating voltage range and multiple low?power modes make it more suitable for battery and energy?harvesting designs. Integrated peripherals also reduce the need for external components and improve overall system reliability.
