MSP430FR59691IRGZR Technical Specifications

MSP430FR59691IRGZR Key Features

• FRAM nonvolatile memory: enables fast, frequent writes with higher endurance and lower energy per write than flash.
• 16?bit CPU: delivers efficient integer math and control for embedded tasks while keeping code size compact.
• Ultra?low power modes: reduce standby energy for longer battery life in portable and remote systems.
• Mixed?signal integration: on?chip ADC, timers, and eUSCI serial modules reduce BOM and simplify PCB routing.

Typical Applications

• Battery-powered sensor nodes that require frequent nonvolatile logging and write cycles while maintaining multi?year standby times.
• Industrial control panels where reliable nonvolatile configuration storage and deterministic real?time timers speed commissioning.
• Portable medical devices that need low power draw, frequent state saves, and deterministic ADC measurements for signal capture.
• Smart metering and energy monitoring where repeated data writes, robust temperature range, and compact integration reduce total system cost.

MSP430FR59691IRGZR Advantages vs Typical Alternatives
