MSP430FR5738IRGET Key Features

• Single 16?bit MSP430 core with deterministic instruction timing for predictable control-loop latencies and tighter real-time response.
• FRAM nonvolatile memory for high?speed, byte?wise writes that reduce write latency and extend data-logging lifetime compared to flash.
• Wide supply range and ultra?low active/standby currents for longer battery life in portable and energy?harvesting designs.
• Integrated 12?bit ADC and multiple serial interfaces to simplify sensor interfacing and reduce external component count.

Typical Applications

• Battery-powered sensor nodes requiring frequent nonvolatile data logging and low sleep current for years of unattended operation.
• Industrial monitoring controllers that need deterministic timing, reliable nonvolatile settings, and robust analog measurement capability.
• Portable medical devices where fast nonvolatile writes, low power draw, and precise ADC measurements improve responsiveness and patient safety.
• Embedded user interfaces and control panels that benefit from multiple serial ports, low standby consumption, and rapid firmware configuration storage.

MSP430FR5738IRGET Advantages vs Typical Alternatives

The device delivers clear advantages versus standard flash?based microcontrollers. FRAM enables orders?of?magnitude faster nonvolatile writes and higher endurance, so systems can log data or update parameters without long write delays or wear?out concerns. The MSP430 core and low supply current yield lower active and standby power than many 32?bit alternatives, making it more efficient for battery and energy?harvesting applications. Integrated analog peripherals and multiple serial interfaces reduce external components and system cost while improving integration and reliability.
