MSP430FR2476TRHAT Key Features

• Single 16-bit MSP430 core delivers efficient instruction throughput for control loops and real-time tasks.
• FRAM-based non-volatile memory reduces write energy and increases endurance versus conventional flash, enabling frequent logging and configuration updates.
• Low-power operating modes extend battery life in portable and remote systems through multiple low-power states.
• Integrated 12-bit ADC and analog peripherals simplify sensor interfacing and reduce external component count for smaller BOMs.

Typical Applications

• Battery-powered sensor nodes where frequent data logging is required and FRAM endurance supports thousands to millions of writes without wear-out.
• Industrial control panels that need robust non-volatile parameter storage, low standby current, and reliable analog measurements across temperature ranges.
• Portable medical devices that demand low energy consumption, fast non-volatile writes for patient data, and compact MCU footprints to meet size constraints.
• Smart metering and energy monitoring where frequent updates, precision ADC readings, and durable non-volatile storage reduce maintenance and increase long-term reliability.

MSP430FR2476TRHAT Advantages vs Typical Alternatives

The FRAM-based device offers more write cycles and faster write speeds compared with flash-based microcontrollers, resulting in lower energy per write and better long-term data logging reliability. With a 16-bit MSP430 core and multiple low-power modes, it provides a more power-efficient choice for duty-cycled and always-on applications. The integrated analog and serial peripherals reduce the need for external ICs, delivering a smaller BOM and more compact PCB area compared to typical MCU-plus-memory alternatives.

FAQ

What is FRAM and why use it?

FRAM, or ferroelectric RAM, is non-volatile memory that supports fast, low-energy writes and very high endurance. It is useful when applications need frequent configuration storage or continuous logging without flash wear-out concerns.

Can this MCU run from a coin cell?

The device supports ultra-low-power modes and a wide operating voltage range, which helps conserve energy in battery-powered systems. Battery suitability depends on system duty cycle and external peripherals.

Which serial interfaces are available?

The microcontroller includes enhanced USCI peripherals that can be configured for UART, SPI, and I2C, enabling flexible communications with sensors, displays, and other ICs.

Is the ADC suitable for sensor measurements?

The integrated 12-bit ADC provides sufficient resolution for many analog sensors; designers should consider input conditioning and reference stability to meet measurement accuracy requirements.

How does FRAM improve product reliability?

FRAM tolerates many more write cycles than flash and writes without erase cycles, which reduces failure modes related to memory wear and simplifies firmware update strategies in long-life deployments.
