• Integrated mixed?signal peripherals including a 12?bit ADC and multiple serial interfaces for straightforward sensor interfacing and system integration.

Typical Applications

• Battery?powered sensing and data logging systems that require frequent nonvolatile writes and long-term data persistence in constrained power budgets.
• Industrial control nodes that need deterministic 16?bit control performance plus reliable nonvolatile firmware and configuration storage across power cycles.
• Human?machine interface controllers where fast write FRAM enables frequent parameter updates and robust retention for touch or key scanning systems.
• Low?power wireless gateways or edge devices that combine ADC inputs, serial comms and persistent state storage for reliable field operation.

MSP430FR59941IRGZT Advantages vs Typical Alternatives

The device delivers tangible benefits versus many flash?based microcontrollers. Its FRAM provides far higher write endurance and faster write cycles, which reduces system latency and simplifies data?logging designs. The 16?bit core offers smaller code size and lower dynamic power for equal control tasks compared with some 32?bit parts. Broad peripheral integration and multiple low?power modes mean fewer external components and longer battery life, which lowers system cost and improves reliability in industrial and portable applications.

FAQ

What memory type does it use?

The device uses ferroelectric RAM (FRAM) as its main nonvolatile memory. FRAM offers faster write times and much higher write endurance than conventional flash, enabling frequent in?field data storage without endurance concerns.

What is the supply voltage range?

Rated operation spans a low voltage range suitable for battery systems. Designers can operate the MCU across typical 1.8 V to 3.6 V rails to support single?cell lithium and multi?rail industrial supplies.

Which communications are supported?

On?chip eUSCI modules implement common serial protocols including I2C, SPI, and UART. These interfaces enable simple connection to sensors, memory devices, and radio modules without external protocol converters.

How does FRAM improve reliability?

FRAM tolerates many more write cycles than flash and completes write operations far faster. This reduces wear?out risk for frequently updated parameters and improves system robustness in logging and calibration tasks.

What temperature range is supported?

The MCU is specified for standard industrial operation from ?40 ??C to +85 ??C. This range suits most factory, field, and outdoor electronics in non?extreme environments.
