MSP430FR2355TRSMR Key Features

• Low-power core ?? reduces standby and active energy use for longer battery life compared with many 8? or 32?bit alternatives.
• FRAM nonvolatile memory ?? enables faster, frequent writes with higher endurance than typical flash, simplifying data-logging and calibration storage.
• Mixed-signal integration ?? includes a 12?bit ADC and analog peripherals to cut external component count and speed prototype-to-production transition.
• Flexible serial I/O ?? dual eUSCI modules support UART, SPI, and I2C, enabling multiple peripheral links and more compact system designs.

Typical Applications

• Battery-powered sensor nodes that require very low standby current and frequent nonvolatile storage of measured data and calibration parameters.
• Industrial transmitters where higher write endurance and fast nonvolatile writes reduce downtime and simplify firmware-controlled logging tasks.
• Handheld measurement instruments that need a 12?bit ADC, compact peripherals, and FRAM for quick settings saves and frequent parameter updates.
• Smart metering or utility devices that use multiple serial links and reliable nonvolatile memory for counters, timestamps, and event records.

MSP430FR2355TRSMR Advantages vs Typical Alternatives

The device offers clear advantages versus many flash-based microcontrollers. Its FRAM gives faster write speeds and far greater write endurance, which reduces system complexity for frequent data logging and calibration. The ultra-low-power MSP430 core lowers both active and standby consumption compared with higher?clocked 32?bit parts, improving battery life. Dual serial modules and integrated 12?bit analog blocks support denser I/O and fewer external components, enabling smaller, lower-cost boards and faster time-to-market.
