MSP430FR4132IG56 Technical Specifications

MSP430FR4132IG56 Key Features

• Single 16-bit MSP430 core with deterministic instruction timing, enabling precise real-time control and lower code size compared to 32-bit alternatives.
• FRAM nonvolatile memory that supports fast, byte-wise writes and high endurance, which reduces firmware design complexity and improves data logging reliability.
• Low-voltage operation down to 1.8 V, which enables longer battery life and broader compatibility than many higher-voltage controllers.
• Compact 56-pin package that integrates multiple I/O and peripheral functions, simplifying board layout and saving PCB area.

Typical Applications

• Battery-powered sensor nodes that require frequent nonvolatile data logging and long operational life while minimizing energy per write.
• Industrial metering and control systems that need deterministic timing and nonvolatile parameter storage across power cycles and brownouts.
• Human-machine interfaces where compact packages and integrated serial peripherals reduce component count and improve reliability on small PCBs.
• Consumer devices requiring low-power modes, rapid wake-up, and durable nonvolatile memory for settings and usage counters over many years.

MSP430FR4132IG56 Advantages vs Typical Alternatives

The MSP430FR4132IG56 combines FRAM memory and an ultra-low-power 16-bit core to deliver lower energy per write and faster nonvolatile updates than standard flash-based MCUs. Compared to many 8-bit and 32-bit alternatives, it often yields smaller code size and lower active power for similar control tasks. The 56-pin package packs more I/O and peripheral options into a smaller footprint than larger DIP or QFP solutions. These factors make it a strong choice where energy efficiency, endurance, and compact integration matter.
