MSP430FR4133IG56 Technical Specifications

MSP430FR4133IG56 Key Features

• Single 16?bit core optimized for deterministic control and compact code density, reducing cycle counts versus 8?bit alternatives.
• FRAM nonvolatile memory enables near?instantaneous writes and extremely high endurance, improving reliability where frequent data logging is required.
• Low operating voltage (1.8?C3.6 V) and multiple low?power modes deliver better energy efficiency for battery?powered systems compared with higher?voltage controllers.
• Integrated mixed?signal peripherals such as a 12?bit ADC and multiple timers simplify system design and reduce the need for external components.

Typical Applications

• Battery?powered sensors and data loggers that require frequent nonvolatile writes and long operational life, minimizing power consumption between samples.
• Industrial control nodes that need deterministic timing, reliable nonvolatile state retention, and compact package options for tight PCB layouts.
• Consumer portable devices with frequent configuration changes and calibration data storage, benefiting from fast FRAM writes and high endurance.
• Smart metering and energy monitoring endpoints that require accurate ADC readings, low standby current, and robust nonvolatile memory for transactional logs.

MSP430FR4133IG56 Advantages vs Typical Alternatives

The device stands out when compared to similar microcontrollers by combining FRAM with a 16?bit core and low supply voltage. This yields faster, more energy?efficient writes and far higher endurance than flash?based parts. In many applications the lower active and standby energy improves battery life by measurable percentages. The compact 56?pin package and integrated mixed?signal peripherals reduce system BOM count and board area versus solutions that require external memory or ADC components.
