MSP430FR2311IPW16 Key Features

• Single 16?bit core with deterministic instruction execution, enabling efficient control code and compact ISR routines.
• Embedded FRAM memory that allows fast, low?energy non?volatile writes, reducing write latency versus flash and improving data-logging cycles.
• Ultra-low supply operation across 1.8?C3.6 V for extended battery life in portable and remote deployments.
• Integrated serial peripherals (UART/SPI/I2C) that simplify sensor, display, and comms integration without external interface ICs.

Typical Applications

• Battery-powered sensor nodes that require frequent non-volatile logging and long standby lifetimes while keeping system size and cost low.
• Portable measurement instruments that need fast, repeated FRAM writes for calibration data and event storage with minimal power overhead.
• Industrial control interfaces where deterministic 16-bit processing and a small 16-pin footprint enable compact boards and simple control loops.
• Consumer user-interface controllers for small appliances, handheld devices, and wearables requiring UART/SPI/I2C and low-power sleep modes.

MSP430FR2311IPW16 Advantages vs Typical Alternatives

The device combines FRAM memory with a 16-bit MCU core for faster non-volatile writes and higher endurance than standard flash-based microcontrollers. It operates across a wider low-voltage range and in a smaller 16-pin package than many alternatives, making it more suitable for space-constrained designs. The integrated serial interfaces and low-power timers reduce external component count and system power, improving overall BOM cost and battery runtime.

FAQ

What is the core architecture?

The device uses a 16-bit RISC CPU core. This architecture delivers compact code, efficient control-flow, and deterministic timing for real-time and low-power embedded tasks.

What non-volatile memory does it use?

This MCU uses embedded FRAM (ferroelectric RAM). FRAM enables fast, low-energy, and high-endurance writes compared with conventional flash memory, which benefits frequent logging and calibration storage.

Which serial interfaces are available?

On-chip serial peripherals include a USCI module supporting UART, SPI, and I2C modes. These enable direct connections to sensors, displays, and communication transceivers without extra interface chips.

What supply voltage range does it support?

The device supports operation across a low-voltage range from 1.8 V up to 3.6 V. This range supports common battery chemistries and single-cell systems while preserving robustness in 3.3 V systems.

Is this MCU suitable for harsh environments?

The specified ambient range covers industrial temperatures from ?40 ??C to +85 ??C. The small VQFN package and low-pin count also support rugged board designs with minimal footprint and thermal mass.
