MSP430F2131IRGET Technical Specifications

MSP430F2131IRGET Key Features

• One 16-bit MSP430 core for compact code and efficient control in small embedded systems.
• Integrated Flash memory enabling in-system program updates and rapid firmware changes.
• Multiple low-power modes that reduce active and standby currents for longer battery life.
• 16-bit Timer_A for precise timing, PWM generation, and capture/compare tasks in motor or sensor control.

Typical Applications

• Battery-powered sensor nodes requiring multi-year operation with duty-cycled sensing and low-power sleep between measurements.
• Portable medical instruments where compact code size, low standby current, and reliable timing are essential for patient monitoring.
• Handheld instrumentation that needs a small footprint MCU with accurate timing and on-chip nonvolatile memory for firmware updates.
• Industrial control endpoints that require robust operation across -40 ??C to +85 ??C and deterministic timer-based control loops.

MSP430F2131IRGET Advantages vs Typical Alternatives

The device offers a compact 16-bit core combined with a small Flash footprint, which reduces BOM cost and board area versus larger 32-bit MCUs. Its low-power modes provide lower standby current than many 8-bit alternatives, making it ideal for battery-driven systems. The integrated 16-bit Timer_A delivers higher-resolution timing than basic 8-bit timers, and the industrial temperature rating supports harsher environments while retaining simple programming and fast wake-up.
