MSP430FR2032IG48 Technical Specifications

MSP430FR2032IG48 Key Features

• Single 16-bit MSP430 core that delivers deterministic code execution and compact instruction density for smaller firmware footprints.
• Integrated FRAM nonvolatile memory that enables faster writes and higher endurance than typical flash, which matters for frequent logging and calibration tasks.
• Wide 1.8 V?C3.6 V supply range to support common battery chemistries and regulated supplies in portable and industrial systems.
• Multiple low-power modes and very low standby leakage to extend battery life in sensor nodes, metering, and handheld controls.
• Two 16-bit timers and up to 32 GPIOs for flexible timing, PWM generation, and direct control of external power stages or LEDs.
• Compact 48-pin VQFN package that reduces board area while keeping enough pins for complex peripheral routing.

Typical Applications

• Battery-powered sensor nodes that require frequent nonvolatile data updates and long sleep intervals to maximize battery life over months or years.
• Smart metering endpoints where fast nonvolatile writes and high write endurance simplify event logging and energy data retention across power cycles.
• Industrial control panels and simple HMIs that need deterministic 16-bit control, multiple I/Os, and low standby current for always-on availability.
• Portable medical devices and handheld instruments needing low-voltage operation, compact packaging, and reliable nonvolatile storage for calibration data.

MSP430FR2032IG48 Advantages vs Typical Alternatives

The device combines FRAM with an MSP430 core to offer faster nonvolatile writes and vastly higher endurance versus typical flash-based MCUs. It operates across a wider low-voltage span (1.8?C3.6 V) and delivers lower active and standby power in many modes, making it a stronger choice for battery-backed and energy-harvesting designs. The 48-pin package gives more I/O per area than many pin-limited chips, while integrated timers and analog support reduce external components.
