MSP430FR4133IG56R Key Features

• Single 16?bit CPU core delivering predictable, deterministic control while using less code space than many 32?bit alternatives.
• FRAM nonvolatile memory that supports far more write endurance and faster write cycles than flash, reducing write latency and increasing system reliability.
• Integrated 12?bit ADC and multiple timers for precise analog measurement and control without external converters, lowering board count and cost.
• Multiple serial interfaces (UART, SPI, I2C) for flexible peripheral connectivity and simpler integration with sensors, displays, and power management ICs.

Typical Applications

• Battery?powered sensor nodes requiring frequent nonvolatile logging and configuration updates while keeping energy consumption under tight budgets.
• Industrial human?machine interfaces that need reliable nonvolatile storage for calibration data and quick write cycles during setup and servicing.
• Portable medical devices that demand deterministic 16?bit control, multiple analog inputs, and robust nonvolatile memory for safety?critical parameters.
• Energy metering and power management controllers that benefit from low?power sleep modes, integrated ADC precision, and durable FRAM for long write endurance.

MSP430FR4133IG56R Advantages vs Typical Alternatives

The device offers FRAM-based memory that outlives conventional flash in write endurance and speed. That improves reliability for frequent logging and frequent configuration changes. At a 16 MHz clock and a 16?bit core, it delivers simpler code and lower active energy per operation than many 32?bit parts in the same class. The 56?pin package provides more GPIO and peripheral muxing than 20?C28 pin variants, enabling higher integration and fewer external components.
