MSP430FR5989IRGCT Technical Specifications

MSP430FR5989IRGCT Key Features

• 16-bit MSP430 core with deterministic instruction timing for precise control tasks and quicker interrupt response.
• FRAM non-volatile memory offering faster writes and higher endurance than typical flash, which matters for frequent data logging and parameter storage.
• Ultra-low-power modes that reduce standby energy draw, improving battery life in portable or remote systems.
• Integrated mixed-signal peripherals (ADC, timers, eUSCI serial modules) that reduce external components and simplify board layout.

Typical Applications

• Battery-powered sensor nodes and wireless endpoints where lower sleep currents extend field lifetime and reduce maintenance cycles for electronics used in industrial monitoring.
• Smart meters and utility metering that require frequent non-volatile data writes and reliable long-term data retention with high endurance memory.
• Human-machine interfaces and touch control panels that benefit from fast non-volatile state updates and integrated serial connectivity for system control.
• Portable medical instruments and handheld diagnostic tools where deterministic 16-bit processing and low-power operation meet strict power and size constraints.

MSP430FR5989IRGCT Advantages vs Typical Alternatives

The device leverages FRAM to provide faster, lower-energy non-volatile writes than typical flash-based MCUs. Compared with similar 16-bit controllers, it offers comparable performance at up to 16 MHz while lowering write latency and increasing endurance. Integrated ADC and multiple serial interfaces reduce the need for external ICs, cutting BOM by multiple components. The broad voltage range (1.8?C3.6 V) and compact 64-pin package make it easier to design for a wider set of systems where power, size, and reliable non-volatile storage are key.
